The Tudor Black Bay 39 features a bold yellow domed dial with contrasting black sub-counters and a date display at 6 o’clock, housed in a 39mm stainless steel case with polished and satin finishes. Powered by the COSC-certified Manufacture Calibre MT5813, this self-winding mechanical chronograph movement uses a bidirectional rotor system and offers a power reserve of approximately 70 hours. The fixed stainless steel bezel is fitted with a black anodised aluminium insert and a tachymetric scale with silver markings. A domed sapphire crystal protects the dial, while the screw-down winding crown with TUDOR shield and screw-down pushers at 2 and 4 o’clock ensure water resistance to 200 metres. Completing the design is a 3-link stainless steel bracelet with polished and satin-brushed finishes and a TUDOR “T-fit” rapid adjustment clasp.
