The TUDOR Black Bay 54 features a 37mm stainless steel case with polished and satin finishes, inspired by historic TUDOR divers’ watches. Its blue domed dial is finished with applied hour markers, Snowflake hands and a classic lollipop seconds hand, all treated with Grade A Swiss Super‑LumiNova®, and protected by a domed sapphire crystal. The watch is powered by the COSC‑certified Manufacture Calibre MT5400, a self‑winding mechanical movement offering approximately 70 hours of power reserve. A 60‑minute unidirectional stainless steel bezel with a blue aluminium insert completes the design. Finished on a blue rubber strap with TUDOR’s “T‑fit” clasp and a screw‑down crown bearing the TUDOR rose, the watch is water‑resistant to 200 metres.
