Breguet Tonneau Perpetual Calendar

About this reference

The Breguet Classique Perpetual Calendar reference 2516 in 18k white gold was produced during the late 1990s and early 2000s and is no longer in current production. Collectors target this reference for its tonneau-shaped case, which deviates from the brand’s traditional round silhouettes while maintaining signature elements like a hand-guilloché silvered gold dial and blued steel Breguet hands. It is powered by the automatic Caliber 502, an ultra-thin movement featuring an off-center rotor. The dial layout includes a moon phase indicator at 1 o'clock and a leap year indicator at 6 o'clock. On the secondary market, this reference typically trades between $18,000 and $25,000 depending on condition and the presence of original accessories. A notable production detail is the use of a solid case back on most examples, though some later iterations featured sapphire displays to showcase the movement finishing.
