Breguet Classique Grande Sonnerie Métiers d'Art 1905

Breguet's Classique Grande Sonnerie Métiers d'Art 1905, reference 1905BH/2H, is a rose gold piece measuring 56.5 mm across. The case stands 24.1 mm thick, a scale dictated by the movement it houses. Manual-winding calibre 508 GS drives the watch, offering 56 hours of power reserve and combining grande and petite sonnerie with a minute repeater and a tourbillon. A sapphire crystal covers the champagne dial, its guilloché finish executed by hand, and a sapphire caseback reveals the mechanism at work. Central seconds sit on the dial alongside the chiming functions. Breguet does not fit a strap or bracelet reference here, as this is conceived as a pocket watch. It carries no water resistance rating and is described as not waterproof.
