Breguet Breguet Expérimentale 1

The Breguet Expérimentale 1, reference E001BH/S9/5ZV, has a 43.5 mm rose gold case. The case measures 13.3 mm thick, with lugs set 22 mm apart. A sapphire crystal covers the blue dial, and the manual-winding calibre 7250 drives the movement, with 72 hours of power reserve. This is the brand's first high-frequency tourbillon built with a magnetic escapement for constant force to the balance wheel. Central seconds and luminous hands round out the display, and the sapphire caseback exposes the movement's finishing. Breguet fits the watch to a rubber strap with a rose gold pin buckle. Water resistance stands at 100 metres.
