Unveiled at Watches & Wonders 2026, the TUDOR Black Bay 58 introduces a new chapter in the evolution of the brand’s celebrated diving-watch collection. Combining vintage-inspired styling with advanced Swiss watchmaking technology, this latest interpretation features a slimmer, redesigned case and enhanced performance, while retaining the distinctive character that has made the Black Bay 58 a favourite among watch enthusiasts.

This 39mm model features a stainless steel case measuring just 11.7mm thick, complemented by a unidirectional rotating bezel with a black anodised aluminium insert and bronze-toned graduations. The domed black dial features contrasting off-white luminescent hour markers, TUDOR’s signature Snowflake hands and a distinctive lollipop seconds hand, paying tribute to the brand’s historic diving watches. A domed sapphire crystal protects the dial, while the watch is presented on a black rubber strap with a stainless steel folding clasp incorporating TUDOR’s T-fit rapid adjustment system for exceptional comfort and a secure fit.

Powered by a METAS-certified Manufacture Calibre self-winding mechanical movement, the Black Bay 58 offers an impressive 65-hour power reserve and resistance to magnetic fields of up to 15,000 gauss. Water resistance to 200 metres completes this exceptional timepiece, bringing together Swiss precision, contemporary engineering and TUDOR’s distinguished diving-watch heritage.
