This 2020 Tudor Black Bay Fifty-Eight, reference 79030N, is the original black-and-gilt 39 mm execution of Tudor’s compact heritage diver. It pairs a domed black dial and black aluminium timing bezel with the brand’s COSC-certified MT5402 automatic calibre and rivet-style steel bracelet.
Why It’s Special
Introduced in 2018, the Black Bay Fifty-Eight takes its name from Tudor’s 1958 reference 7924 ‘Big Crown’ diver. Its 39 mm case deliberately returns the Black Bay to proportions closer to Tudor’s mid-century dive watches, while the snowflake hands and gilt details reference historic Tudor design cues. It became a modern collector touchstone by combining that vintage vocabulary with Tudor’s contemporary manufacture movement.
Condition
Black dial is clean and original with crisp printing and no visible spotting or degradation. Lume plots are intact and evenly coloured, with matching handset. Sapphire crystal is clean, with no visible scratches. Stainless steel case remains sharp with light surface wear; no major dents or signs of heavy polishing, with case geometry well preserved. Bezel insert is clean with crisp numerals and minimal wear, while bezel action remains firm and correctly aligned. Crown retains a sharp Tudor rose engraving. Caseback shows light handling marks. Genuine Tudor rivet-style bracelet presents well, with minimal stretch and light desk wear to the clasp; it includes its full links.
Performance
Recently tested on timegrapher at –4 seconds per day. Strong performance for a modern automatic sports watch and suitable for regular daily wear.
