Breguet Classique 5157

Breguet Classique 5157, reference 5157BR/11/9V6, has an extra-flat rose gold case measuring 38 mm across. The case is 5.5 mm thick, a proportion that keeps the profile close to the wrist. A sapphire crystal covers the silver guilloché dial, hand-engraved on a rose engine turning lathe, and the display back is also sapphire. Inside is the self-winding calibre 502.3, which runs with a 45-hour power reserve and drives a central seconds display. The dial keeps to the classic Breguet layout of Roman numerals and blued hollow hands. An alligator leather strap closes with a rose gold pin buckle. The case holds its 30 metre water resistance rating through the non-screwed crown.
