Breguet Perpetual Calendar Moonphase Ref. 3050 BB crafted in 18k white gold, a rare and highly desirable model created by master watchmaker Daniel Roth for Breguet.

Its silvered dial is finished with finely executed Clous de Paris guilloché and features four subdials indicating the day, date, month with leap year cycle, and moonphase. Completing the display are the iconic blued steel Breguet hands.

The case, with its signature coin-edge, measures 36mm across and just 8mm in thickness, and houses the self-winding calibre.

This example is fitted on a Breguet leather strap with 18k gold tang buckle, and comes accompanied by its distinctive 18k gold setting pin, which can be attached to the watch by the chain. Also includes Breguet service paper from 12/2025. Circa 1980s.
