2026 Tudor M79000-0001 Black Bay 54 Lagoon Blue Unworn Full Set
M79000-0001 • 37mm • Lagoon Blue Textured Dial • Full Set
OVERVIEW
The 2026 Tudor Black Bay 54 “Lagoon Blue” combines vintage-inspired dive-watch proportions with a distinctive modern colorway and dependable everyday performance.
This unworn example features a compact 37mm stainless-steel case, a domed and textured Lagoon Blue dial, and a mirror-polished stainless-steel bezel. The bright blue dial gives the watch a unique appearance while maintaining the clean, understated design associated with the Black Bay collection.
The watch is powered by Tudor’s Manufacture Calibre MT5400 automatic movement. The COSC-certified movement provides an approximately 70-hour power reserve, allowing the watch to be set aside for a weekend without requiring immediate rewinding.
A five-link stainless-steel bracelet completes the design and is equipped with Tudor’s T-fit rapid-adjustment clasp for improved comfort and convenient sizing.
Offered unworn with its complete original set and 2026 warranty card, this Black Bay 54 is an excellent option for collectors seeking a factory-fresh example of Tudor’s Lagoon Blue configuration.
