DeBethune DB17 Perpetual Calendar (2005)

18k rose gold case in 43mm with a thickness of 12mm. Manual winding movement DB2004, using the inhouse patented 4 spoke titanium balance with platinum weights. 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.
