About This Watch
Sixty years of Tudor dive-watch mastery, distilled into a single all-steel expression. The Black Bay Steel Ref. M79730-0004 marries the collection's unmistakable heritage silhouette — domed crystal, bold bezel, and the legendary "snowflake" hands first seen on Tudor's professional diving instruments of the 1960s — with the modern convenience of a date function. The result is a timepiece that honours the past without being trapped by it, offering the wearability of a contemporary sports watch and the soul of a horological icon.
At its heart beats the TUDOR Manufacture Calibre MT5612, a self-winding movement developed and produced entirely in-house. The bidirectional rotor system delivers an impressive power reserve of approximately 70 hours, ensuring the watch keeps pace across a long weekend without needing a wind. COSC-level precision standards and Tudor's own stringent testing regime guarantee accuracy that rivals movements costing several times as much, cementing the Black Bay Steel as one of the shrewdest value propositions in modern watchmaking.
Crafted from polished and brushed 316L stainless steel, the case and bracelet strike a balance between understated elegance and tool-watch robustness. The broad, cathedral-style bracelet tapers elegantly toward the clasp, replicating the feel of vintage references that collectors have long prized. Whether paired with a diving suit or a business-casual shirt, the Black Bay Steel Ref. M79730-0004 wears with an authority that belies its accessible price point — a true dare in steel, exactly as Hans Wilsdorf intended when he founded Tudor in 1926.
