The Tudor Black Bay GMT S&G reference M79833MN-0001 is a compelling fusion of classic dive-watch heritage and modern GMT functionality, designed for travellers and style-conscious collectors alike. Part of Tudor’s celebrated Black Bay family, this model combines robust tool-watch performance with luxurious bi-metal design, making it a standout choice in the world of pre-owned luxury watches.
Offered here in mint condition and supplied with its original box and papers as a full set, this version features a distinguished stainless steel and yellow gold construction. The 41 mm case is finished with both polished and satin surfaces, contributing to a refined yet sporty presence on the wrist while retaining the durability expected from a Black Bay timepiece.
The dial is a striking matte black, accented by gold-tone applied hour markers and the signature “Snowflake” hands, providing excellent legibility and a distinctive visual identity. A bidirectional 48-notch bezel with a complementary black and brown 24-hour insert enables intuitive tracking of a second time zone — an essential feature for global travellers.
At the heart of this timepiece is Tudor’s manufacture calibre MT5652, a Swiss automatic movement with COSC-certified chronometer precision, a 70-hour power reserve, and independent adjustable GMT function, allowing local time to be set without stopping the movement. The combination of rugged build quality, classic design cues and functional GMT complication places this Black Bay GMT S&G amongst the most desirable dual-time sports watches available.
Whether for daily wear or as the centrepiece of a collection, this Tudor Black Bay GMT S&G represents an exceptional opportunity to acquire a certified pre-owned luxury watch that balances performance, aesthetic appeal and mechanical ingenuity.
