Perpetual calendar with astronomical moonphase. Power reserve is 5 days. Several technical aspects make this a very interesting watch to collect; first of all a legible perpetual calendar is something not talked about more often enough. Many perpetual calendar on the market are simply impossible to read; this DB17 is very legible with a simplistic approach in dial design. Secondly, the moonphase is not only incredible because of its Astronomical Moonphase ability (meaning its accurate up to 122 years), but also it is a spherical moon, adding even more uniqueness to the watch. Produced in very small quantity in the early days of the brands’ launch.

This is perhaps the most elegant perpetual calendar I can think of. The large aperture at 3 o’clock is the date. The up/down at 9 o’clock is a power reserve. The small arrow hand pointing to an hour is the month. To keep the dial clean, the watch doesn’t tell you the day of the week. However, being a perpetual calendar, it must be able to see the the leap year indicator on the watch and to maintain the spirit of keeping the watch clean and elegant, the leap year indication is hidden away on movement side of the watch. The watch is adjusted via simply only thru the crown, and it can be adjusted forward or backward (unlike many other perpetual on the market which can only be adjusted forward), leap year is adjusted by the corrector on the side of the case at 9 o’clock. The date indicator is a large date display with two discs overlapping each other; and it is an instantaneous jumping display.
