Overview

The Tudor Black Bay Fifty-Eight 18K reference 79018V pairs the line's signature 39 mm case with solid 18k yellow gold construction and a richly toned green dial. It represents Tudor's most precious-metal expression of the Black Bay Fifty-Eight, a sub-line defined by its compact, wearable dimensions and mid-twentieth-century diver aesthetics. The green dial variant, introduced as part of the 18K offering from 2021 onward, adds a layer of chromatic depth that plays warmly against the yellow gold case.

History

The Black Bay Fifty-Eight name references 1958, the year Tudor introduced one of its earliest references rated to 200 metres — a lineage the modern collection consciously evokes in its case diameter, snowflake-style hands, and domed crystal. Tudor expanded the Fifty-Eight into precious metals in the early 2020s, marking a notable step for a manufacture historically associated with steel sport watches. The 79018V in yellow gold with a green dial arrived in 2021, broadening the palette of the 18K family and aligning with a broader industry enthusiasm for green dials in fine watchmaking.

Notable points

  • Case crafted entirely in 18k yellow gold, an uncommon material choice for a tool-watch-derived Tudor reference.
  • The 39 mm diameter is deliberately restrained, echoing vintage diver proportions and offering a wearable alternative to larger modern sport watches.
  • Powered by the in-house Tudor calibre MT5400, a COSC-certified movement featuring a silicon balance spring and a 70-hour power reserve.
  • The deep green dial creates a striking tonal contrast with the warm yellow gold case, a combination with strong roots in mid-century dress-sport watch design.
  • Retains functional diver credentials — including a unidirectional rotating bezel and water resistance — despite its precious-metal construction.
