  • Catalogue Essay

    Taking inspiration from divers' wristwatches manufactured by the firm in the 1950s, the new Tudor Black Bay iteration of the original ref. 7922 was introduced at Baselworld 2012. Extremely well executed, the case retains its “no crown guard” style with a dial extremely similar to its original model, and became a commercial success when it was launched to the public.

    The present Tudor Black Bay GMT was part of the firm’s novelties introduced in Baselworld 2018. Launched as the first GMT model in the Black Bay lineup, it was widely accepted that it featured a multi-colored “Pepsi” bezel insert paying obvious homage to the Rolex GMT-Master. Maintaining much of an identical aesthetic in case design to its other Black Bay counterparts, the GMT model is slightly larger at 41mm, catering to contemporary demand. The case and dial is balanced with a modernized riveted-style bracelet and the timepiece is without a doubt one of the most perfectly executed modern iterations of a vintage professional diver’s watch.

    The present example is presented in “brand new” condition retaining its full factory protective stickers on the case and clasp. As showcased on the dial and case back, this particular example was specially commissioned by Italian official retailer "Ronchi" for its 90th Anniversary, and is accompanied by the full set of accessories with a guarantee card dated 2020. The present example number 65 of 90 is perhaps the perfect option for a collector seeking for a modern GMT wristwatch.

  • Artist Biography


    Swiss • 1926

    Almost twenty years after Rolex was founded, Hans Wilsdorf established Tudor with the intention of making more affordable watches without compromising the quality for which Rolex was renowned. Tudor was named after the British Dynasty that ruled England from 1485 to 1603, and their symbol came from the "War of Roses." After interchanging Rose and Shield symbols for a number of years, the firm replaced the Rose with the Shield logo from the 1960s until today.

    Some of the most recognized vintage models made by Tudor include the Submariner, a waterproof model first introduced in 1954, the Oysterdate, the earliest versions of which were nicknamed the "Monte-Carlo," the Heritage, which included the date at 6 o'clock, as well as the Pelagos, which translates to "deep sea" in Greek.
