Perfecting the Perfect Dive Watch

Part 1: The Watches

It is the year of our Lord Twenty O Six. And upon this day, the first of September, Rolex has unveiled a subtle yet significant evolution to its most iconic model, the Submariner. A watch that is inextricably linked with cinema, worn by some of the most iconic men and women on earth, and has played a role in shaping human history since its launch, in 1953.

What is important to understand is that each time Rolex presents a new version of the Submariner, or any of their near mythological timepieces, it does not do this for the sake of creating novelty. Quite the opposite, each time Rolex launches a new model it forges the next link in an ongoing evolutionary process, characterized by steady improvement to every single dimension of that watch. It does so to incrementally advance every aspect of its timepieces solidifying them as the most reliable and best executed luxury sports watches on the planet.

Today as we look at the all-new Submariner family, comprising of the No-Date Reference 124060, which replaces the 114060, introduced back in 2012, and the Reference 126610, which replaces the revered 116610, launched back in 2010. We will take a look at the details of these watches from the perspective of its case, dial, bezel, movement and bracelet and how they represent functional improvements in the Submariner, all in aid of Rolex’s perennial quest to perfect the already perfect dive watch.

The New 41mm Case

As you have probably just experienced when you saw the statistic “41mm”, initially a wave of apprehension swept through the Revolution office when we first learned that Rolex was increasing the size of the seemingly perfect 116610 case by 1 millimeter. We immediately remarked, “But everyone is going to more classic proportions, why is Rolex making the Submariner bigger.” But rest assured that increase in size is purely a paper statistic. Because the case of the new 124060 and the 126610 actually feels smaller, slimmer and more elegant than its predecessor.

A side by side comparison of the 2020 ref. 126610 with the outgoing 2010 ref. 116610 both in Oystersteel; at 41mm the new Submariner case represents a marginal increase in size from its predecessors 40 mm in diameter and is still a full 2mm smaller than the 43mm diameter of its deep saturation dive sibling the Sea-Dweller.

The case is an all new design. At 41mm the new Submariner case represents a marginal increase in size from its predecessor’s 40mm diameter and is still a full 2mm smaller than the 43mm diameter of its deep saturation dive sibling, the Sea-Dweller. This case, like its predecessor’s, is a Maxi-Style case characterized by its robust shape and distinct crown guards, but somehow more refined.

That’s thanks to a subtle but complete redesign of the case profile of the watch, characterized by two important things. For the “Maxi” style crown guards, these have been reduced significantly in size so that while they still offer the same function of protecting the crown, the area around the crown feels quite a bit less chunky. Second and equally importantly the new case lugs tapers more sharply towards their junction with the bracelet making the case feel svelte and dynamic.

It is still in effect a “Maxi Case” in design but a more svelte and elegant form. On the wrist the difference is immediately apparent making the new Submariner feel more able to slip subtly under the cuff of a shirt, while still retaining some of the muscular presence of the Maxi case, first introduced in 2005 in the GMT Master-II model with ceramic bezel.

The crown is of the Triplock variety launched by Rolex in 1970 to equip the deep diving Sea-Dweller model and that features three sealed zones based on two gaskets within the winding tube and one just under the crown. The Triplock made it way to the Submariner in 1977, in the model 1680, where it has stayed ever since.

However, beyond the design of the case, we should pause to discuss the material it is made from, specifically Oystersteel. While all other brands use the industry standard of 316L stainless steel, it is only Rolex that uses 904L stainless steel. What is 904L steel and how does is it distinguished from 316L steel? Well, it features a much higher corrosion resistance as well as a higher surface hardness than 316L. Since inception, the tradition at Rolex is to always research the way their watches wear over time. And they found that with hard use, their sports watches, like others made from traditional stainless steel, would experience corrosion in the threads of the caseback and the caseback itself, because of the buildup of sweat and moisture. 904L steel was selected as a new material because of its resistance to acids. Further its greater surface hardness not only improved the resistance of the cases but enabled them to be polished to a greater luster.

904L steel is received by Rolex and then scanned with an electron microscope for any imperfections, including any structural or surface defect. After inspection, the steel is re-melted in a vacuum to purify it and remove inclusions that would compromise its corrosion resistance. As you can see, Rolex’s focus is on creating watches that endure forever. Why do other brands not use 904L? Because it is much harder to machine and requires special tools to do so.

The very first Rolex Submariner model to use this material, which Rolex refers to as Oystersteel, is the reference 168000, a transitional model from 1987 that uses the same movement and dial as the 16800, made from 1979-1987 but the case from the 16610 which was launched in 1988.  By 2003 all Rolex steel watches were using 904L based Oystersteel.

The Maxi Dial

The Submariner dial with its combination of round and rectangular markers with an inverted triangle at 12 o’clock is the most iconic sports watch dial in existence. Combined with the “Mercedes” style hour hand and pencil shape minute hand, there is no mistaking a Submariner, whether on land or in the darkest depths of the ocean.

The dials of the new 124060 and 126610 Submariners are gloss dials with applied white gold luminous indexes. They feature slightly larger luminous plots, as well as hands, to aid in visibility particularly underwater than pre-2003 watches and are referred to as Maxi Dials.

Reference 5512 and 5513 were the first Rolex Submariners to feature Maxi Dials in some iterations. These were largely matte dials that had large luminous indexes painted directly onto them. The first Submariner to feature a gloss dial with applied white gold indexes filled with luminous paint was the 16800, starting in 1984, a feature that would be carried over to the 16610 Submariner Date launched in 1999 and the 14060 Submariner No Date launched in 1989. But the first modern Maxi Dial with oversized applied markers and hands on a gloss dial, appeared on the famous Kermit or 16610LV made from 2003-2010. This Maxi Dial was then carried over to the 116610 introduced in 2010 and remains with us today.

Chromalight

From the beginning, the Submariner is a model that required perfect visibility even in the low light conditions underwater. As such, Rolex has used various luminous compounds from radium to tritium to Luminova to create luminous hands and indexes for its sports watches.

Today, while the majority of other watch brands use SuperLuminova to create its luminous indexes, Rolex launched Chromalight back in 2008 with the creation of the Sea-Dweller Deep Sea. Chromalight glows blue in the dark, as opposed to the green of SuperLuminova and instead of glowing very bright and then quickly fading away, it features a much more stable luminous intensity which lasts much longer than conventional alternatives. The 124060 and the 126610 both use Chromalight treated indexes and hands to offer luminous indications that remain bright, more consistently, over a longer duration than most other watches.

In 2008, Rolex launched the Sea-Dweller DEEPSEA ref. 116660, which featured Chromalight as Rolex's choice of lume material for the first time; Chromalight stands apart from the industry standard, SuperLuminova with its blue glow as opposed to the latter's green glow

The Cerachrom Bezel

Like their predecessors, the 124060 and the 126610 Submariners use Cerachrom ceramic bezel inserts, which have now been adopted across all of Rolex’s sports watches. Why ceramic? Because ceramic has the highest Vickers rating for hardness for any material besides diamond. In its ongoing quest to create the most durable and reliable watches, in 2005 Rolex began its transition from aluminum bezel inserts for its various turning bezels to ceramic inserts.

Over the last 15 years Rolex has been at the forefront of ceramic technology creating some of the most beautiful colored bezel inserts for watches such as the white gold and blue bezel Submariner from 2008, the green dial and green bezel Submariner known as the “Hulk” from 2010 and of course the world’s first two color ceramic bezels blue and black for the model known as the “Batman” in 2013  and in blue and red for the GMT Master II model known as the “Pepsi” in 2014. Since its introduction in 2010 the Submariner Date 116610 and the Submariner No Date 114060 in 2012 both featured ceramic bezels.

At the start basic ceramic preparations, are always in powder form; binding agents are added to the powder preparations, which include a mixture of zirconia and color pigments or alumina; the mixture is heated and then injected into molds at high pressure to create a blank; this step gives the piece its shape and molds the numerals, graduations and inscriptions

Let’s take a quick look at the Cerachrom manufacturing process. Ceramic starts out in powdered form made of two materials, Zr02 and Al203. A binding agent is added to it before it is heated and placed in a mold. When it comes out it has not yet achieved the surface hardness of ceramic and so indexes are molded into it. Then the ring is heated to 1500º Celsius in a process called sintering, which eliminates the binding, agent causes the ceramic to harden and shrink by 25 percent. Chemicals are added during sintering to create the color required.

The negative voids for the indexes of these bezels are already present when they come out of the sintering process. Next a layer of PVD in platinum is applied for white text or gold for gold colored text. Then the entire surface of the bezel is diamond polished to remove the excess PVD material and also to render a high gloss finish to the bezel.

The new 124060 uses a ceramic bezel in black. While the new 126610 Submariner Date references include ceramic bezels in blue for a white gold model with a black dial, royal blue for a Rolesor model with a blue dial, green and black for a Oystersteel model with black dial. Note that the capsule for the luminous pearl is made in gold.

Each Cerachrom bezel insert takes 40 hours to manufacture. In addition to a being virtually impervious to scratches, it is also not affected by UV light and will therefore never fade in color, indeed its vibrancy will endure forever.

Sapphire Crystal

It’s funny no one ever really talks about Sapphire crystal in sport watches and the immense advantage they offer. While today Sapphire crystal has become the industry norm, it is important to understand that Rolex was a pioneer in the use of sapphire crystal in their watches.

Sapphire crystal is grown from monocrystalline aluminum oxide. It is far more scratch and shatter resistant than mineral glass and has a Mohs scale hardness of 9, which is exceeded only by diamond, with a Mohs scale hardness of 10.

While a small handful of high luxury watches had begun to adopt sapphire crystal in the 70’s (notably AP with the Royal Oak in 1972), Rolex was the first brand to adopt sapphire over acrylic crystals for its sport range of watches. The integration of sapphire crystals at Rolex began with Beta 21 Quartz watch reference 5100 in 1970, then made its way to the reference 1530 Date watch in 1975, to the Oyster Quartz in 1977, to the Day-Date in 1978 to the Sea-Dweller in 16660 in 1978 and then to the Submariner, namely model 16800, in 1979.

The first Submariner to use a sapphire crystal was the 1979 ref. 16800, which also allowed the watch its new 300m depth rating

Glidelock Bracelet

Since the creation of the Submariner watch back in 1953, it has always been synonymous with the Rolex Oyster link bracelet. It has followed an evolutionary process in keeping with the advances represented by the watch head.

The manufacturing process has gone from riveted (1953), to folded (1967), to folded with solid end links to where it is today with solid links (1975). Similarly, the clasp of the Submariner has also changed with time. In 1969 the Submariner was the first Rolex to receive an extra secure lock on top of the folded clasp system, which also hid a simple but extremely efficient extra link for expansion over a dive suit.

All of the new Submariner range of watches feature Rolex’s Glidelock deployant clasp. The first watch with the incredible Glidelock system for rapidly adjusting the length of your bracelet by up to 2cm was the Rolex DEEPSEA Sea-Dweller, launched in 2008. With this system by lifting up the tip of the clasp that normally fits under the safety lock, you release the bracelet where it is fixed inside of the deployant. Then you can glide the bracelet to make it either smaller of larger by up to 2cm in 2mm increments.

The Glidlock was introduced to the Submariner Date family with the creation of the 116610 in 2010 and the Submariner No-Date with the 114060, in 2012. In precious metal versions of this bracelet there is a ceramic insert for the teeth of the micro adjustment system so as the protect them from wearing out prematurely.

Oyster Perpetual Calibres 3230 & 3235

Increasing water resistance and innovations to the case, dial and bracelet represent only part of Rolex’s focus on technical advancement and progress over the 67 year evolution of the Rolex Submariner.

Over the history of the model reliability, shock resistance and accuracy in time keeping has always been of paramount importance and this comes down to the movement driving the Submariner Date and No Date watches. The movements that have powered the Submariner including the 1575, 3035, 3135, with Date, and the 3000, 3130, without Date, are some of the most beloved in watchmaking history.

By 2010, for the Submariner Date 116610 and by 2012 for the Submariner No Date 114060, Rolex had switched over to truly excellent movements, respectively the 3135 and 3130 calibres, featuring the Parachrom hairspring. Like all 31-series movements, they beat at 4Hz, or 28,800vph, (this vibrational speed was introduced with the 3035, in 1981, in the reference 16800).

They featured a free sprung balance with Microstella adjustments screws, which has been a Rolex calling card since the 30-series movements. They both featured full transverse balance bridges as opposed to balance cocks in the previous 30-series movements, and overcoil hairsprings for more concentric breathing, as opposed to flat spirals. Further, these hairsprings were laser welded to the stud, while hairsprings in the 30-series of movements were glued. Being made from Parachrom these hairsprings were not susceptible the erosive effects of magnetism.

So how do you improve on an already impressive movement? In 2015, Rolex responded with the launch of the Calibre 3235, an automatic movement with date, which represented an incredible leap forward in terms of performance in terms of accuracy, reliability, shock resistance and power reserve. This movement would feature 90 percent new components, an increase of power reserve from 50 to 70 hours, a proprietary escapement that was 15 percent more efficient and 14 patents.

Let’s look at the innovations represented by the incredible 3235 which this year makes its way to the new Submariner Date as well as the all new Calibre 3230 that powers the new Submariner No Date watch.

Chronergy Escapement

The vast majority of the Swiss watch industry relies on the tried and tested Swiss anchor escapement. This escapement however has two vulnerabilities. The first is that the way in which the pallets contact the sliding face of the escapement wheel results in sliding friction. Second is it generally manufactured in traditional materials it is susceptible to becoming magnetized.

The Rolex Chronergy Escapement
The Rolex Chronergy Escapement

The Chronergy Escapement is Rolex’s proprietary design for a better snchor style escapement. What sets it apart? (1) First, the geometry of the lever is offset to better optimize leverage on the pallet fork. (2) Second in the Chronoergy escapement the pallets are 50 percent thinner than on previous units while the contact surfaces on the escape wheel have doubled in size. (3) Third the escapement wheel is made using LIGA (galvanically grown) from nickel phosphorous, which means it is impervious to magnetism as well as significantly lighter than a steel escape wheel, taking less energy to restart each time. Knowing Rolex’s attention to detail pivots and other smaller parts are likely made from non-magnetic material as well. Rolex tells us the Chronergy escapement increases efficiency by 15 percent.

Parachrom Hairspring

The Calibres 3235 and 3230 use hairsprings created from a material patented by Rolex called Parachrom. These hairsprings are easy to spot, thanks to their unique blue color.

Insensitive to magnetic fields, the Rolex Parachrom hairspring offers great stability against temperature variations and is 10 times more precise than a traditional hairspring in case of shocks.
Insensitive to magnetic fields, the Rolex Parachrom hairspring offers great stability against temperature variations and is 10 times more precise than a traditional hairspring in case of shocks.

What’s Parachrom? It’s a proprietary material made from 85 percent Niobium and 15 percent Zirconium. Niobium is a bad ass refractory metal with high heat resistant, wear resistance and an incredible memory. There are images of bike mechanics (in the pre-carbon fiber era) smashing Niobium rims into curves only to have them bounce back into shape. Zirconium is a highly malleable metal extremely resistant to corrosion. The metals are bonded together at 2400 degrees and drawn through a series of dies. Afoot long shaft is pulled into a 2-kilometer-long metal thread that is 1/10th of a millimeter. This is all done in-house at Rolex.

The final spring (1 foot of Parachrom makes 10,000 springs) is 150 microns wide and 45 microns high. It is coiled then separated by hand and has a Phillips terminal curve made by a special machine created by Rolex before being fixed to a balance wheel, where it will beat in your watch — shrugging off shock, temperature variation and all forms of inclemency with total bad-ass reliability. Parachrom has the additional significant advantages of not being affected by magnetism and is up to 10 times more shock resistant than other metal hairsprings.

The first Parachrom hairsprings were placed in the in-house vertical clutch chronograph calibre 4130 for the Daytona back in 2000. The Parachrom hairspring was also used in the 31-series movements, such as the caliber 3186 used for the GMT Master II and was carried over to the 32-series of movements.

Increased 70-Hour Power Reserve

Rolex has also increased the power reserve of the new movements first through the gain in 15 percent efficiency thanks to the new Chronergy escapement. The escape wheel is skeletonized and despite having more surface area is lighter and has less inertia and the escapement design produces less sliding friction. At the same time Rolex reduced the thickness of the barrel walls by 50 percent meaning the mainspring could be longer and hold 10 more hours of charge for a total of 70 hours.

Full Traversing Balance Bridge

This implementation began with the 3130 and the 3135 movements. The 3130 made its appearance in the No Date Submariner reference 14060M, from 1987, while the 3135 made its appearance in the 16610, from 1988. As opposed to the 3000 and the 3035 calibres these movements had full traversing balance bridges fixed on both sides.

The 3230 and 3235 have in-house designed Paraflex shock absorbers that bisect the jewels diagonally and retain it with a rectangular frame. These shock absorbers were designed and patented by Rolex in 2005, and aid in increasing shock resistance by an incredible 50 percent. They are also much easier to service.

There is, also, yellow screw on the balance. This helps to maintain the position of the traversing balance bridge and keeps it stable. It can be used to adjust the height of the bridge n order to ensure the calibre’s chronometric performance.

Other Improvements

Other improvements to the 3200 series movements include a friction fit balance staff, a monobloc one-piece automatic rotor, mounted on ceramic ball bearing for more efficient winding — just to throw a few extras in there.

The Rolex Superlative Chronometer Test

Each 32-series movement undergoes Rolex’s in-house Superlative Chronometer test. As opposed to other tests such as COSC, which only tests movements (the criteria have changed recently) Rolex prefers to test entire watches. Further while COSC certification requires movements to test within -4/+6 seconds maximum deviation per day, Rolex’s criteria is much stricter at -2/+2 seconds. Rolex is the only one of two sports watch brands that subjects its watches to a double certification process.

Since 2018, Rolex has demarcated all of their Superlative Chronometer rated watches with a new coronet printed between the words "Swiss Made" at 6 o'clock; this now also appears on the dial of the 2020 family of Submariner watches (©Revolution)
