Tudor M79830RB-0001

The Tudor Black Bay GMT is a professional diver's watch that also incorporates a GMT complication, allowing you to track a second time zone. It is part of the popular Black Bay collection and is easily recognized by its red and blue 'Pepsi' 24-hour bezel and signature snowflake hands. It was launched in 2018 and remains in production.

The official retail price (MSRP) for this watch is $4,675. Based on market data from tracked listings, the median pre-owned price is around $3,750, with a typical range from about $2,480 to $4,210. It is generally seen as a more accessible alternative to the Rolex GMT-Master II.

The watch features a 41mm stainless steel case that is 14.6mm thick, offering a substantial wrist presence. It has a 200-meter water resistance rating, a sapphire crystal, and a bidirectional 24-hour 'Pepsi' bezel. It also includes a date function and a 'Rivet' style bracelet.

Many enthusiasts consider it excellent value due to its high-end specifications like COSC certification, 70-hour power reserve, and robust build at its price point. Its market price often trades below its retail MSRP, potentially offering savings on the pre-owned market.

With a 41mm diameter and a 14.6mm thickness, the watch has a substantial, tool-watch feel that may be noticeable on smaller wrists. The combination of its size, the riveted bracelet, and the prominent bezel gives it a bold and robust presence.

The Tudor Black Bay GMT shares the iconic 'Pepsi' bezel theme and GMT function with the Rolex GMT-Master II but at a significantly lower price point. While the Tudor offers its own design language with snowflake hands and a distinct case, it is often seen as the more attainable sibling within the broader Rolex family.

Potential buyers should consider the watch's substantial 14.6mm thickness and 41mm case diameter to ensure it fits their wrist comfortably. On the pre-owned market, verifying the watch's condition and authenticity is crucial, as prices can vary significantly from around $2,480 to over $4,200.

The watch is powered by an in-house automatic movement that is COSC-certified for chronometer-level accuracy. A key technical feature highlighted by Tudor is its 70-hour power reserve, which allows the watch to run for nearly three days when not worn.
