The famous Black Bay family introduced the first TUDOR chronograph, powered by the self-winding Manufacture Calibre MT5813, with a column wheel and vertical clutch. To mark 50 years of its chronographs, TUDOR is relaunching its Black Bay Chrono model in steel with a reworked case. The recognisable characteristics of the Black Bay are preserved in a steel case with a 41-millimetre diameter. A fixed bezel in stainless steel with a tachymetric scale insert in black anodised aluminium completes the distinguished appearance of this sporty new chronograph.
