Hot on the tail of the launch of the Legacy Machine Perpetual Yellow Gold comes the all new MB&F Legacy Machine Perpetual EVO. While the earlier version was a particularly classical execution of the watch in the regalest of precious metals, the EVO is a decidedly more edgy execution of the watch in Zirconium.

MB&F Legacy Machine Perpetual EVO

Why Zirconium? MB&F states that Zirconium is lighter than steel and more durable than titanium. In fact, Zirconium is said to have similar physical properties as titanium in terms of its durability and corrosion resistance, but with the added advantage of its heightened biocompatibility. Zirconium is, therefore, is often seen used in various medical applications such as dental implants and surgeries.

Aside from the material used, the watch design in itself has also been updated for a more progressive appearance. Take for instance that the domed, bulbous sapphire crystal, it now goes from edge-to-edge on the case of the EVO, sans bezel. Don’t take for granted that this was an easy feat, and it’s not that MB&F just glued the crystal onto case. A thermal bonding process has been used to ensure that the glass and Zirconium of the case are secured to one another, providing ease of mind for regular wear and water resistance of up to 80 meters.

Truth be told, this matter of making the watch easier for regular wear is a serious one for the EVO. First there is the new security measure on the winding stem of the watch’s crown, which disengages the crown from the winding mechanism when it is pushed in and tightened. This prevents against any chance of manual over-winding of the mainspring barrel.

Then we have these protruding pushers for adjustment of the calendar functions of the EVO. In previous LM Perpetuals you would’ve seen these as small round pushers made to sit flush with the surface of the case, which therein requires a pusher pin to manipulate. The new protruding pushers make sure that you are able to adjust the watch no matter where you are, without having to carry the specific pusher pin.

Yet another addition is the FlexRing: a circular dampener placed between the case and movement, which provides shock protection along the vertical and lateral axes — another score for everyday use.

Various fortification and ease of use aside, of course, what’s use to catch the eye first is the dynamic colors used for the EVO. These are applied to the dial plate by means of Chemical Vapor Deposition (CVD) for the orange and blue, and Physical Vapor Deposition (PVD) for the black. The black on the subdials is achieved by means of a galvanic treatment with the etched numerals further treated with Super-LumiNova.
