Tudor · Family: Black Bay
The Tudor Black Bay S&G (Steel & Gold) ref. M79733N is the 41mm two-tone execution of the brand's dive watch, introduced in 2017 with a yellow gold rotating bezel, a riveted steel-and-gold bracelet, and the in-house Calibre MT5612. Cazador has no verified price observations yet. Its differential: it's the rotating-bezel, 200m-rated execution, distinct from the fixed-bezel Black Bay 31/36/39/41 S&G dress line Tudor launched later, in 2022.

Tudor introduced the Black Bay S&G — short for "Steel & Gold" — at Baselworld 2017, marking the return of the steel-and-yellow-gold combination to one of the brand's dive watches after years in which two-tone had largely disappeared from sport-watch catalogs across the industry. Reference M79733N keeps the architecture of the standard Black Bay it's built on: a 41mm case, a unidirectional rotating bezel, and a domed sapphire crystal, but with the bezel made in yellow gold with a black insert and a matching gold-capped crown.
The movement is the in-house Calibre MT5612, COSC-certified as a chronometer, with a silicon hairspring and a double bridge stabilizing the balance wheel for improved rate stability. It delivers a 70-hour power reserve at a 4Hz beat rate, with hours, minutes, seconds, and date functions.
The bracelet mixes steel and yellow gold links with visible rivets, a styling nod to vintage Tudor and Rolex bracelets from the 1970s and '80s. The reference also ships with a matching fabric strap option, or an aged-leather strap with a folding buckle depending on retailer and configuration.
At 200 meters of water resistance, the Black Bay S&G keeps the dive-tool intent of the wider Black Bay family, unlike the fixed-bezel Black Bay 31/36/39/41 S&G line Tudor introduced in 2022 as a dressier proposition, with different calibers (MT5201, MT5400, MT5601, and MT5602 depending on size) and only 100 meters of water resistance — a separate line that shares material naming but not case architecture or bezel with the M79733N.
As of this writing, the Tudor Black Bay S&G M79733N remains in the brand's current catalog.
