Breguet Héritage Chronographe 5400

Breguet's Héritage Chronographe 5400, reference 5400BB/12/9V6, has a tonneau-shaped white gold case measuring 42 mm in height. The case runs 14.5 mm thick, with lugs set at 20 mm apart. A sapphire crystal covers the silver dial, which is worked by hand in guilloché across its various sections. This is a chronograph, and the movement, Breguet's self-winding calibre 550/1, also drives a date function and small seconds. Power reserve stands at 42 hours. The dial is paired with an alligator leather strap on a white gold folding clasp. Water resistance reaches 30 metres, modest for a piece built around such fine dial work.
