The Tudor Heritage Black Bay ref. 79250BM is the bronze-cased iteration of the Black Bay dive watch family, introduced with a distinctive aged bronze case and matching unidirectional rotating dive bezel finished in a weathered brown tone. This 2018 example presents a 43mm bronze case paired with a brown dial, its aged bronze surface developing the natural patina characteristic of this alloy over time. The dial carries applied luminous markers, a snowflake hour hand, and printed chronometer certification text, consistent with the Black Bay's design language, with the rotating 0-60 dive bezel set beneath a domed crystal. Inside the case is the automatic Tudor manufacture caliber MT5601, offering a 70-hour power reserve and displaying hours, minutes, and seconds. The watch is presented on an unworn brown Tudor NATO strap, riding on a case built for daily wear with a screw-down crown typical of the line. This example is in excellent condition and comes as a full set with additional accessories. Excellent with Tudor box and papers dated 2018.
