🔎 Case Notes

The Tudor Black Bay GMT “Pepsi Opaline” Ref. 79830RB is one of the most striking modern versions of the Black Bay GMT line. It keeps the familiar burgundy-and-blue bezel, 41mm case, and true GMT functionality of the standard model, but the opaline dial changes the entire feel of the watch. The contrast is sharper, the overall look is brighter, and the watch feels more distinctive on the wrist than the original black-dial version.

What makes this reference especially appealing is that it retains all the strengths of the Black Bay GMT platform while adding a dial execution that collectors notice immediately. The opaline surface gives the watch a slightly more contemporary and more expressive presence, but it still stays firmly within Tudor’s core design language. It still has the familiar case shape, snowflake hands, bidirectional 24-hour bezel, and practical travel-ready character that made the Black Bay GMT such a success.

This example dates to 2024 and is presented in like new pre-owned condition. Overall, it presents exceptionally clean. It includes box, papers, and cards and is currently sized to fit approximately a 7.75-inch wrist.

🌍 GMT Heritage

The Black Bay GMT takes Tudor’s vintage-inspired dive-watch language and adapts it for travel use, combining the collection’s familiar snowflake hands, domed dial, and rotating bezel format with true GMT functionality. The result is a watch that still feels unmistakably like a Black Bay, but with the added practicality of tracking multiple time zones.

The opaline version gives that formula a different personality. Where the original black-dial GMT leans more traditional and tool-like, the opaline dial creates more contrast, more brightness, and a more immediately eye-catching presentation. It feels more distinctive without losing the rugged practicality that made the Black Bay GMT such a success in the first place.

🌟 Collector Provenance

The Black Bay GMT has already built a strong following within Tudor’s modern lineup, but the opaline dial has become one of the more desirable executions because it gives the reference a noticeably different look while keeping the same proven platform. For buyers who want the Black Bay GMT experience with a little more presence and more visual distinction, this is one of the easiest versions to gravitate toward.

Examples that include box, papers, and cards remain especially attractive, and this one also benefits from a strong bracelet fit. For someone looking for a modern Tudor GMT with broad everyday utility and more visual character than the standard black-dial version, this is a very compelling example.
