Editor's Notes
Divers watches with handsome good looks, the TUDOR Black Bay collection brings together sixty years of diving heritage and conjures it into each and every timepiece. Housing TUDOR created movements and ‘snowflake’ hands (a nod to the TUDOR watches used by the French National Navy in the 1970s), function and reliability lie at the core of every watch.
A showstopper on the inside as well as the outside - the self-winding mechanical Manufacture Calibre MT5201 movement with a bidirectional rotor system promises no more late mornings, while the power reserve of 50 hours and 100m water resistance means you can rely on this watch every single day.
