Tudor Black Bay Fifty Eight 925 79010SG

The Tudor Black Bay Fifty-Eight 925 Ref. 79010SG is one of the most distinctive and innovative dive watches Tudor has ever produced, becoming the first model in the brand's history to feature a solid 925 silver case. Inspired by the original Tudor Submariner Ref. 7924 "Big Crown" from 1958, the watch retains the perfectly balanced 39mm proportions that have made the Black Bay Fifty-Eight collection so beloved among enthusiasts. Its satin-finished sterling silver case develops a subtle character over time while maintaining a refined appearance thanks to Tudor's specially developed alloy, which is engineered to resist excessive tarnishing. Complementing the case is a warm taupe domed dial and matching anodized aluminum bezel insert, creating a sophisticated monochromatic aesthetic unlike any other luxury dive watch on the market. The addition of an exhibition sapphire caseback—another first for the Black Bay collection—offers a glimpse into the beautifully finished manufacture movement within.

Powering the 79010SG is Tudor's COSC-certified Manufacture Caliber MT5400, an automatic movement featuring a silicon balance spring, variable inertia balance, and an impressive 70-hour power reserve. With 200 meters of water resistance, a screw-down crown, domed sapphire crystal, and exceptional everyday wearability, the Black Bay Fifty-Eight 925 remains every bit a professional dive watch despite its luxurious construction. What truly sets this reference apart is its unique combination of precious-metal craftsmanship and vintage-inspired tool-watch design. For collectors seeking something beyond the traditional stainless steel sports watch, the Black Bay Fifty-Eight 925 delivers an extraordinary blend of innovation, heritage, and understated elegance, making it one of the most original and compelling references in Tudor's modern lineup.
