Featuring a deep rich blue dial with diamonds on the indexes, the Black Bay One 31 from TUDOR is an elegant yet powerful Swiss watch. Departing from the traditional Black Bay tool watch aesthetic, the Black Bay One 31 is designed for those wanting to make a statement in the office or at formal occasions.
The watch itself is powered by the MT5201 (COSC) which is a self-winding mechanical movement with a bidirectional rotor system. Alongside this, it has a 50 hour power reserve and is water resistant up to 100m, ensuring that not only will you never miss a second, but it is built to last.
