Overview
The Tudor Black Bay Fifty-Eight ref. 79030N is a 39 mm stainless steel dive watch distinguished by its black dial with gilt accents — a colour pairing that directly evokes Tudor's mid-twentieth-century diving references. Introduced in 2018, it occupies a deliberate middle ground within the Black Bay family, offering a slimmer, more wrist-friendly proposition than its larger siblings without sacrificing the line's characteristic depth-rated robustness. The "Fifty-Eight" name itself is a nod to the year 1958, when Tudor produced one of its earliest references rated to 200 metres.
History
Tudor's Black Bay line was conceived as a modern reinterpretation of the brand's long heritage of tool diving watches, drawing on design cues accumulated across several decades of professional-grade references. The Fifty-Eight variant was launched at Baselworld 2018 as a direct response to collector demand for a more compact, vintage-proportioned option within the range. The 79030N specifically pairs the black-and-gold aesthetic with an in-house movement, reflecting Tudor's broader push — accelerated through the 2010s — toward manufacturing its own calibres. Its slim profile and gilt detailing quickly made it one of the most discussed references in the contemporary mid-range dive-watch segment.
Notable points
- The 39 mm case diameter is notably smaller than the standard Black Bay's 41 mm, making the Fifty-Eight a preferred choice for collectors with slimmer wrists or a preference for vintage-era proportions.
- The black dial with gilt (gold-toned) indices and hands references Tudor's so-called 'black bay' references of the 1950s and 1960s, where such colour combinations were common on professional dive watches.
- Power is supplied by the in-house Calibre MT5402, a COSC-certified movement offering a 70-hour power reserve and fitted with a silicon balance spring for improved magnetic resistance.
- The snowflake hour hand — a long-running Tudor design signature first appearing on its dive watches in the 1960s — is retained on the 79030N, anchoring it visually to the broader Black Bay family.
- A fabric strap in a heritage-style weave is included alongside a steel bracelet option, underscoring the vintage-inspired character of the reference.
