TUDOR
Ref. M79640-0005
Black Bay One 36mm
Ref. M79640-0005
Powerful and bold, the TUDOR Black Bay One 36 is marked by its deep blue dial and diamond index. The curved case breaks away from the Black Bay's traditional tool watch aesthetic for something more refined.
The watch itself is powered by the MT5400 (COSC) which ensures that you never miss a beat. With a 70 hour power reserve and water resistant up to 100m, it is not only a stunning timepiece, but one that is designed for wearing every day. Moreover, the stainless steel bracelet also features TUDOR's "T-fit" clasp which allows you to make on-the-fly size adjustments up to 8mm.
