The Clifton Perpetual Calendar has a mechanical memory of 1461 days, the equivalent of four years, which animates the self-winding Vaucher 5401 movement within the watch, which also happens to be beautifully finished with Côtes de Genève on the bridges and stippling on the bottom plate. A micro-rotor, often the reserve of a select few in the watchmaking world, makes it possible to pare down the movement for a case that is barely 4.2mm thick. You can gaze into the caseback to appreciate the movement which ticks away at 21,600 vibrations/hour and boasts a power reserve of 48 hours. However, the highlight for me is the delightful raised sapphire “chevé” crystal, designed for improved readability which gives a vintage feel to the watch. The dial is silvered opaline with numerals and stamped indexes in red gold and blued hands indicate the watch’s calendar functions. The date appears at 3 o’clock, the days of the week at 9 o’clock while the months and the leap years appear at 12 o’clock.
The Clifton Perpetual Calendar represents the final piece in the collection, ultimately showcasing that Baume & Mercier is ready and able to produce more complex – great looking watches at reasonable prices each and every year.
