The Tudor Black Bay GMT ref. 79830RB is stunning in this opaline configuration and the light dial completely changes the character of the familiar “Pepsi” GMT. The domed opaline dial has a subtle silvery-white tone with darkened marker surrounds, contrasted against the matte burgundy and blue 24-hour bezel. The combination gives the watch a very different look from the original black-dial Black Bay GMT.
What separates this reference from a conventional Black Bay is the GMT functionality and Tudor’s Manufacture Calibre MT5652. The automatic movement was developed specifically for the Black Bay GMT and provides approximately 70 hours of power reserve, with an independently adjustable jumping local-hour hand. The bidirectional 24-hour bezel and dedicated GMT hand allow the watch to track multiple time zones.
The burgundy-and-blue bezel is another defining feature of the Black Bay GMT, with the two colors distinguishing daylight and nighttime hours on the 24-hour scale. Combined with the opaline dial, stainless-steel construction, and modern MT5652 movement, this configuration gives the Black Bay GMT a distinctive look that is quite different from the more familiar black-dial version. This particular example is from 2025, is in very good condition, and comes as a complete set.
Please view pictures carefully as I use a very strong macro lens to showcase any and all imperfections. Typically, this will embellish the imperfections and/or lead to the inevitable specks of dust. I am always happy to provide more pictures at different angles, whatever you're unsure of.
I am a full time firefighter and am very involved in my community - my reputation is everything to me. Please feel free to reach out with any questions and I will answer promptly to make sure you are taken care of and we can have a smooth easy transaction.
