Tudor Black Bay 54

Tudor Black Bay 54 Ref. M79000N-0001

The Tudor Black Bay 54, reference 7900N (M79000N), from 2024 is the purest and most masterfully proportioned tribute to the origins of the brand's diving watch history at Tudor. With its 37 mm case diameter, it exactly reproduces the dimensions of the very first Tudor dive watch – the legendary reference 7922 from 1954. Rather than simply copying a nostalgic design, Tudor combines the authentic vintage feel of the 1950s with the highest standards of modern manufacturing, COSC certification and the innovative T-Fit clasp in this model.

• Perfectly proportioned 37 mm stainless steel case: Crafted from finely brushed and polished 316L stainless steel. The case stands out with its slim profile, prominent polished bevels on the lugs and the omission of crown guards, faithfully echoing the silhouette of the 1950s originals.

• Bezel without five-minute markings: The unidirectional stainless steel bezel with black Aluminium insert deliberately omits the minute graduations for the first five minutes – a historical detail taken directly from Ref. 7922.

• Subtly domed dial with sunburst finish & Gilt Dial aesthetic: The black dial features a subtle sunburst finish and gilt accents (Gilt Dial) on the minute track, the lettering and the hand surrounds.

• Historically accurate “Snowflake” hands & hand design: Equipped with the distinctive Snowflake hands and the delicately designed seconds hand with its round, luminous diamond-shaped marker (Lollipop).

• Manufacture automatic caliber MT5400 (COSC-certified): Powered by Tudor's in-house movement with a robust balance bridge, an antimagnetic silicon balance spring and a frequency of 28.800 beats per hour (4 Hz). It offers a “weekend-proof” power reserve of approx. 70 hours with accuracy, that exceeds COSC requirements (-2/+4 seconds per day when cased).

• Highly domed Sapphire Crystal: Delivers the nostalgic domed effect of classic plexiglass, while offering the absolute scratch resistance of modern Sapphire Crystal technology.

• Screw-down crown with a relief Tudor rose: Oversized winding crown without crown guards, decorated with the embossed historic Tudor rose.

• Guaranteed water resistance (200m / 20 ATM): Offers fully professional diving capabilities and complete reliability for everyday wear and water sports.

• Three-link stainless steel bracelet with “T-fit” quick-adjust clasp: Delivered on the riveted stainless steel bracelet (Rivet-Style) with the patented T-fit clasp from Tudor, allowing precise, tool-free length adjustment in 5 positions across a range of 8 mm.

• Purist Heritage Masterpiece (2024 model): Reference 7900N is the ultimate vintage-inspired timepiece for collectors and lovers of classic proportions - a perfect tribute to 70 years of Tudor diving watch heritage.
