Reference: M79000B-0001 • 37mm • Sapphire Blue Dial • Brand New Full Set
The Tudor Black Bay 54 "Blue" M79000B-0001 represents a fresh interpretation of one of Tudor's most successful modern dive watches. Combining vintage-inspired proportions with contemporary materials and performance, the Black Bay 54 delivers exceptional versatility in a compact and highly wearable 37mm case.
This newly released 2026 model features Tudor's distinctive sapphire-blue sunray-brushed dial paired with a matching blue bezel, creating a striking and refined aesthetic. Drawing inspiration from Tudor's historic dive watches while incorporating modern design elements, the Black Bay 54 offers a balanced combination of heritage, comfort, and everyday practicality.
Powering the watch is Tudor's in-house Manufacture Calibre MT5400 automatic movement, which provides approximately 70 hours of power reserve and COSC-certified performance. The addition of Tudor's T-fit rapid-adjustment clasp further enhances wearability by allowing quick, tool-free bracelet adjustments throughout the day.
Dated August 11, 2026, this example is brand new and unworn and is offered as a complete full set. With its recently introduced sapphire-blue colorway, compact dimensions, and impressive specifications, the Black Bay 54 "Blue" has quickly become one of Tudor's most desirable current-production models.
