Tudor Black Bay GMT Ref. 79830RB – Heritage Design, Global Utility

The Tudor Black Bay GMT Ref. 79830RB is the perfect blend of vintage-inspired styling and world-time functionality—offering serious tool watch credentials with unmistakable nods to Tudor's legacy. With its striking "Pepsi" red and blue aluminum bezel, this reference quickly became one of the most recognizable and sought-after GMT watches in the modern Tudor lineup.

This particular example features a rare white dial, a crisp and contemporary contrast to the classic bicolor bezel. The clean surface enhances the visibility of the bold black surrounds on the snowflake hour hand and matching indices, while the vibrant red GMT hand tracks a second time zone against the 24-hour scale. With its robust stainless steel case sized at 41mm, the watch offers a confident presence while maintaining the proportions and curved lugs that make the Black Bay line so wearable.

Powering the watch is the in-house Tudor Caliber MT5652, a COSC-certified automatic movement with a 70-hour power reserve, bidirectional rotor, and full independent GMT function. It's built for reliability and rugged use, featuring a silicon balance spring for enhanced resistance to shocks and magnetism.

The watch comes fitted on a satin-brushed solid-link steel bracelet with a secure folding clasp and safety catch, echoing vintage Rolex and Tudor Oyster styles. A domed sapphire crystal and 200 meters of water resistance make this as capable as it is handsome—ready for jetsetting or everyday adventure.

The Tudor Black Bay GMT 79830RB delivers true GMT function, timeless design language, and bulletproof construction—all wrapped in one of the most appealing vintage-modern packages on the market today. With its polar dial and classic color palette, this is a travel watch with a distinctive character all its own.
