Tudor · Family: Black Bay
The Tudor Heritage Black Bay Bronze (ref. 79250BM) was, in 2016, the first bronze version of the Black Bay line, with a 43mm case in an aluminum-bronze alloy that ages and develops patina with wear. As of August 2026, Cazador has 0 verified price observations. Its differential trait: it runs Caliber MT5601, the first movement entirely designed, developed, and manufactured in-house by Tudor, COSC-certified as a chronometer.

In 2016, Tudor expanded its Black Bay family with a novelty more about material than design: the Heritage Black Bay Bronze, the line's first reference made from an aluminum-bronze alloy, a direct nod to the metal's use in the instrumentation of historic ships and vintage diving equipment.
Like all bronze watches, this piece starts out with a warm, golden tone that, over time and through contact with skin and the environment, shifts toward the characteristic green of bronze patina, a process that unfolds differently for each watch depending on how its owner wears it. To encourage even aging, Tudor changed the case finish: instead of the polished look of other Black Bay versions, this execution has a uniform brushed finish, even on the lug chamfers.
Since bronze isn't hypoallergenic, the case back is made of stainless steel with a PVD treatment that mimics bronze's tone. The case grows to 43mm in diameter — versus the 41mm typical of the standard Black Bay of that era — with 200 meters of water resistance and a bronze bezel with a brown acrylic insert.
Beneath the brown, aged-effect dial with dateless snowflake hands sits Caliber MT5601, the first movement entirely designed, developed, and manufactured in-house by Tudor under its "Manufacture Tudor" (MT) designation. COSC-certified as a chronometer, it beats at 4Hz with a silicon balance spring and delivers 70 hours of power reserve, figures that in 2016 put Tudor at the technical level of far more expensive manufactures.

It's a natural oxidation process from contact with air, sweat, and water, shifting the original warm, golden tone toward the characteristic green of bronze patina. Each watch ages differently depending on how it's worn.
Because bronze isn't a hypoallergenic material and can irritate skin with prolonged contact. Tudor uses stainless steel with a PVD treatment that visually mimics bronze's tone.
It's the first movement entirely designed, developed, and manufactured in-house by Tudor, COSC-certified as a chronometer, with a silicon balance spring and 70 hours of power reserve.
No. The 2016 bronze execution is a time-only version — hours, minutes, and seconds — with no date window, unlike other Black Bay versions from the same era.
It's rated to 200 meters, suitable for use as a dive watch.
