Breguet 5157BB Classique 18K White Gold Silver Dial

Reference 5157BB/11/9V6 sits within Breguet's Classique line, the collection that most directly carries the house codes established by Abraham-Louis Breguet into modern production. This reference pairs a 38 mm 18K white gold case with an ultra-thin profile of just 5.5 mm, giving it the restrained proportions collectors expect from a formal Breguet dress watch. The silvered dial is hand-guilloche, with Roman numerals, blued open-tipped hands, an individual number, and the discreet secret signature that mark out the brand's traditional dial work. Power comes from caliber 502.3, an extra-thin self-winding movement with an off-center rotor architecture and a silicon balance spring, details that matter in a watch where mechanical refinement is as important as exterior finish. Breguet uses the fluted caseband here, along with a signed crown and sapphire display back, keeping the reference visually anchored in the Maison's long-standing design language. The 5157 is not a limited edition, and I am not able to verify a country or boutique-specific release for this exact reference from public brand data. Its significance lies instead in execution: a modern automatic dress watch that preserves the proportions, guilloche work, and classical hand style that define the best contemporary Breguet Classique references. For collectors focused on ultra-thin precious metal dress watches, this reference offers a notably pure expression of the category, with very little on the dial or case to distract from proportion, finishing, and movement quality. It is a watch for buyers who value traditional horology rendered with modern technical updates rather than reinterpretation. Like New with Breguet travel pouch and undated papers.
