🔎 Case Notes

The Tudor Black Bay GMT Ref. 79830RB is one of the most recognizable modern travel watches in Tudor’s lineup — a piece that combines heritage-inspired design with true GMT functionality.

The defining feature is the red and blue “Pepsi” bezel, a classic colorway long associated with dual-time watches. Paired with the matte black dial and signature snowflake hands, the watch delivers strong contrast and excellent legibility.

At 41mm, the case offers a solid wrist presence while maintaining everyday wearability. The watch carries Tudor’s robust tool-watch construction, making it equally suited for travel, daily wear, and more demanding use.

This example dates to 2021 and is presented in excellent pre-owned condition, showing minimal signs of careful wear. The dial and sapphire crystal remain clean, and the case and bracelet present very well.
