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.

With the Manufacture Calibre MT5652 (COSC) at the helm, you know you’re in good hands. Plus, the 70 hour power reserve means you’ll never be out of time with this timepiece donning your wrist.
