Rolex founder Hans Wilsdorf launched the Tudor Watch Company in 1946 in an effort to offer the public reliable timepieces at affordable prices. Since 2015, Tudor has been manufacturing in-house movements to much acclaim.


This Tudor Black Bay watch for men is a COSC-certified chronometer, so you can count on precision and reliability in every regard. As a self-winding automatic watch, this timepiece is driven by the Manufacture MT5602 caliber, which delivers a fabulous 70-hour power reserve.

With its screw-down winding crown, closed case back, and terrific 200 m / 20 atm water resistance, this is a rugged dive watch that will make a great partner on your next dive mission. Especially helpful is the unidirectionally rotating bezel with a matte black 60-minute graduated insert.

Its stainless steel case measures 41 mm in diameter and it rests upon an aged black leather strap with a stainless steel folding buckle for added safety. The domed crystal is composed of scratch-resistant sapphire. Applied luminous hour markers and hands can be spotted easily in low light, as can the orange minute track, which stands out in lovely contrast to the black-colored dial.

From its precision construction to its sporty stylings, this Black Bay dive watch by Tudor will make a great addition to your collection.
