Overview
The Tudor Black Bay GMT S&G reference 79833MN pairs a 41 mm bi-material case — combining polished yellow gold elements with stainless steel — with a black dial and the in-house calibre MT5652, offering a simultaneous second time zone display. It occupies a distinctive position within the Black Bay family, bringing a dressy warmth to what is otherwise a tool-watch lineage. The S&G designation signals Tudor's considered use of steel-and-gold construction, a combination with deep roots in mid-century Swiss watchmaking.
History
Tudor introduced the Black Bay GMT line as an extension of its heritage-inspired Black Bay collection, drawing on the brand's long association with robust, legible GMT watches. The S&G variant, introduced in 2022, represents Tudor's move toward more formally dressed interpretations of the Black Bay GMT, echoing the two-tone aesthetic that was popular across Swiss sports watches of earlier decades. The calibre MT5652 — developed and manufactured in-house — underscores Tudor's commitment, sustained over the 2010s and into the 2020s, to producing its own certified movements. Collector interest in the reference has been shaped by the relative rarity of steel-and-gold GMT watches at Tudor's market tier.
Notable points
- 41 mm case combines stainless steel with yellow gold accents, giving the watch a two-tone character uncommon in the Black Bay GMT range.
- The in-house calibre MT5652 provides a true GMT complication, displaying a second time zone via an additional hand and a bidirectional 24-hour bezel insert.
- A black dial creates strong contrast against the yellow gold indices and hands, maintaining legibility while reinforcing the dressy character of the S&G execution.
- The Black Bay GMT S&G entered production in 2022, making it among the more recent additions to the broader Black Bay family.
- Tudor's S&G references sit within a long Swiss tradition of pairing steel cases with gold bezels, crowns, and applied elements — a combination historically associated with versatility across formal and casual contexts.
