UNWORN Tudor Black Bay 58 GMT "Coke" Master Chronometer M7939G1A0NRU
A Modern Traveler's GMT in the Perfect Proportions
The Black Bay 58 has become one of Tudor's defining collections thanks to its vintage-inspired proportions, everyday versatility, and exceptional value. With the introduction of the Black Bay 58 GMT, Tudor has expanded the collection into one of its most practical offerings, pairing the beloved 39 millimeter case with true traveler GMT functionality and a METAS-certified Master Chronometer movement. The result is a watch equally at home crossing time zones or serving as an everyday companion.
Originally purchased from an authorized dealer in June 2026, this unworn example remains in like-new condition and includes its complete presentation set.

Why We Like It
The Black Bay 58 GMT succeeds because it delivers exactly what many collectors have been asking Tudor to build for years. Rather than simply shrinking an existing GMT model, Tudor engineered a purpose-built traveler GMT around the Black Bay 58 platform, preserving the collection's comfortable 39 millimeter proportions while incorporating a true independently adjustable local hour hand. The result is a GMT that wears beautifully whether you're traveling internationally or simply appreciating the convenience of tracking another time zone.
Equally impressive is what lies beneath the dial. The MT5450-U is not only a true GMT movement but also carries METAS Master Chronometer certification, meeting rigorous standards for accuracy, magnetic resistance, and overall performance. Paired with the striking black and burgundy bezel, refined five-link bracelet with Tudor's outstanding T-fit clasp, unworn condition, and remaining factory warranty, this reference represents one of the most complete and technically capable luxury GMT watches available anywhere near its price point.
