Technically, the new H. Moser & Cie Endeavour Perpetual Calendar Purity remains identical to the previous editions of the Schaffhausen-based Manufacture’s QP. And to be honest, no complaints, as there’s not much to improve on this movement. Indeed, it certainly one of the most ingenious perpetual calendars of the current production, especially because of its visual simplicity and user-friendly daily use. The display is somehow basic at first, as mainly the date is visible – large and well positioned, but yet rather alone. Still, there’s more, with a tiny hand on the central axis, which displays the months. The leap year, indispensable feature of a QP (but not a useful one on a daily basis) is positioned on the back. This entirely in-house manufactured movement has over 7 days of power reserve and the ‘Double Pull Crown’ feature, which allows a correction of the date by turning the crown (without disturbing the time setting) and set the time precisely (with a hack-second system), as well as an adjustment both forward and backward of the calendar, at any time of the day… More at Monochrome.
Oh my. That is gobsmackingly beautiful.
