Vacheron Constantin Fiftysix self-winding

Vacheron Constantin's Fiftysix self-winding 4600E/000A-B487 is a 40 mm steel watch with a petrol blue dial. The case measures 9.6 mm thick and carries a sapphire crystal, with a date aperture at 3 o'clock and a central seconds hand. Self-winding calibre 1326 drives the watch, offering 48 hours of power reserve, and its finishing is visible through the sapphire caseback. Hour markers and hands are highlighted with luminous treatment for legibility in low light. The dial's opaline centre and sunburst exterior sit against a dark blue alligator leather strap. A steel folding clasp secures the watch to the wrist. Water resistance is rated to 30 metres.
