Reference 3737 stands among the most fascinating and elusive creations of modern Breguet. Introduced after the landmark ref. 3430 of the 1991 Souscription set, the 3737 - made under the aegis of Daniel Roth - combines two of the most revered complications in watchmaking: the minute repeater and the perpetual calendar. Believed to have been produced in only a handful of examples, it is a true rarity within the brand’s contemporary history. Encased in yellow gold, its aesthetic is defined by a solid gold dial with a brushed outer ring and finely guilloché center, brought to life with Breguet’s unmistakable blued steel hands. Furthermore, amongst the few examples known, to the best of our research this example is the only one featuring blued screws on the movement.

At its heart lies the calibre 567, based on the Lemania cal. 399 minute-repeating movement, with a perpetual calendar module integrated on top. Technically captivating and visually distinctive, the movement is adorned with triple finger bridges and lavish Côte de Genève decoration, embodying both mechanical complexity and refined finishing. A grail of 1990s haute horlogerie, the 3737 also underscores Breguet’s enduring role as one of the true guardians of traditional watchmaking excellence—especially poignant as the firm marks its 250th anniversary this year.

Offered with its original self-winding presentation box and certificate of origin, the present example represents an exceptional opportunity to acquire a historically important, extraordinarily rare, and eminently elegant Breguet complication.
