SIGNED BREGUET, CLASSIC COMPLICATION MODEL, REF. 3797, CASE NO. 535 BP, CIRCA 2017

This stunning example of the House of Breguet’s 21st century complicated watches, the reference 3797 semi-skeletonized perpetual calendar tourbillon with retrograde date combines superb aesthetics with classic complications.

In very good overall condition and offered with the full set of accessories, this masterpiece is a fitting tribute to the horological legacy of Abraham Louis Breguet and captures the genius and essence of Breguet’s original ideas.

The manual winding entirely hand-engraved movement features the one-minute tourbillon, a device for equalizing positional errors that was invented and patented by Abraham-Louis Breguet himself in 1801, and a perpetual calendar which self-adjusts for the number of days in the month and the leap-years. A fascinating feature of the calendar is the retrograde date indication at the top of the dial, an ingenious system whereby when the hand reaches either 30 or 31, depending on the number of days in the month, it instantaneously ‘flies’ back to the 1 position. The classic Breguet 42 mm. diam. case with polished bezels, straight lugs and reeded band is glazed on both sides to allow the full beauty and technical virtuosity of the movement to be appreciated.
