Founded in 1926 in Geneva, Switzerland, Tudor is known for its robust tool watches and strong connection to professional diving and exploration history. The Black Bay collection represents the brand’s modern interpretation of classic tool watches, combining heritage aesthetics with contemporary performance.

The Tudor Black Bay GMT with white dial, reference 79830RB, is a versatile travel watch designed for tracking multiple time zones. The watch features a 41 mm stainless steel case paired with a white dial. Applied luminous hour markers, the signature Snowflake hands, and the distinctive red GMT hand ensure excellent legibility. Powered by the Tudor caliber MT5652 automatic movement, it offers a power reserve of approximately 70 hours, a frequency of 28,800 vph, COSC certification, and functions including GMT, hours, minutes, seconds, and date.

A domed sapphire crystal protects the dial, while the bidirectional red and blue aluminum bezel enables tracking of a second time zone. Water resistance is rated at 200 meters. The watch is fitted on a stainless steel bracelet with a folding clasp.

This Black Bay GMT is in near mint condition and comes as a full set.
