Founded in 1926 by Hans Wilsdorf, Tudor has built its reputation on producing robust, reliable, and stylish tool watches with a strong connection to its sister brand Rolex. The Black Bay line embodies Tudor’s heritage in diving and exploration, blending vintage cues with modern design and manufacturing standards. The Black Bay 39 delivers this aesthetic in a versatile, contemporary size.

The Tudor Black Bay One 39, reference M70663, features a 39 mm stainless steel case with Tudor’s signature polished and satin-brushed surfaces. The elegant dial layout includes luminous hands and hour markers inspired by the brand’s mid-20th-century dive watches. Powered by the in-house Tudor caliber MT5602 automatic movement, it offers a 70-hour power reserve, a frequency of 28,800 vph, a silicon balance spring, and COSC-certified chronometer performance. Functions include hours, minutes, and central seconds.

A sapphire crystal protects the dial, while the smooth fixed bezel gives the watch a more refined and versatile character compared to traditional dive models. With 100 meters of water resistance and a screw-down crown, the Black Bay 39 is suitable for everyday wear. This model is fitted on a stainless steel bracelet with Tudor’s T-fit clasp system, offering precise and tool-free adjustment.

This Tudor Black Bay One 39 is in near mint condition and comes as a full set.
