  • The Manufacture Calibre MT5400 displays hour, minute and second functions. It has the finish typical of TUDOR Manufacture Calibres: Its rotor in tungsten monobloc is openwork and satin-brushed with sand-blasted details, and its bridges and mainplate have alternate sand-blasted, polished surfaces and laser decorations.

  • The Black Bay One models bring a unique aesthetic to the Black Bay line. The curved cases feature a combination of finishes that elevates the watch in a contemporary fashion and offers a design language that slightly departs from the brand’s iconic tool watch spirit to embrace a sophisticated, versatile, unisex chic look and feel. Fitted with Manufacture Calibres these models are at the cutting edge of technical watchmaking refinement.

  • All Black Bay One models are available on a five-link bracelet in 316L steel. It comes complete with a robust clasp in 316L steel with TUDOR "T-fit" rapid adjustment system for on the fly size changes. Easy to use, requiring no tools and offering five positions, this practical system allows the wearer to carry out a fine, instant adjustment of up to 8mm on the clasp.
