About the Tudor Black Bay

Tudor introduced the Black Bay in 2012, taking its design from the brand's dive watches of the 1950s. Today's models use Tudor's own manufacture movements, in several sizes including the 39 mm Black Bay 58.

Check the rotating bezel's action and the bracelet or strap. Sizes vary (for example 39 mm and 41 mm), so compare the reference as well as the name.

We stock 553 Tudor Black Bay watches, from $2,025 to $35,640.
