🔎 Case Notes

The Tudor Black Bay 58 GMT “Coke” Ref. 7939G1A0NRU represents one of the newest and most talked-about additions to the Black Bay lineup — combining the beloved BB58 proportions with Tudor’s modern GMT functionality.

What immediately defines this reference is its black and red “Coke” bezel, a classic color pairing historically associated with dual-time travel watches. The aluminum bezel insert offers a vintage-inspired aesthetic while providing the practical ability to track a second time zone.

Unlike earlier Tudor GMT models with larger case dimensions, this watch brings the complication into the more compact BB58 platform, giving collectors a highly wearable GMT with the familiar Black Bay design language. The watch maintains Tudor’s robust tool-watch build quality while remaining comfortable enough for everyday wear.

This example is presented in excellent pre-owned condition, showing minimal signs of wear. The dial and crystal remain clean and the case retains strong lines. The watch is currently sized for approximately a 7.25-inch wrist.

While the watch itself is offered watch only, it includes a non-Tudor display box suitable for storage and presentation.
