De Bethune DB17 Perpetual Calendar

While De Bethune gets a lot of credit for their flashy, futuristic blue watches, some of their consistently most beautiful pieces have been their perpetual calendars. This DB17 is an absolutely jaw-dropping take on the classic complication. It features a white gold case, ruthenium guilloche dial, signature 3D moonphase with blued star disk that cleverly contains the leap year indicator, and gorgeously formed gold hands. The movement fuses classic and modern: hand-finished plates, wheels and bridges including a deliciously black-polished large balance bridge that forms part of the ingenious DB shock absorption system and holds one of their wild modern balance wheels.
