About this watch

The latest evolution of Tudor’s iconic diver, the Black Bay 54 Lagoon Blue, brings refined proportions and a striking new dial color to the collection. At 37mm, this stainless steel timepiece recalls the brand’s earliest dive watches from 1954, now enhanced with a vivid lagoon blue dial and bezel insert for a modern twist. Powered by Tudor’s in-house COSC-certified Calibre MT5400 with a 70-hour power reserve, it pairs vintage charm with cutting-edge performance. Water resistant to 200 meters and offered on either a riveted steel bracelet or a sporty rubber strap, the Black Bay 54 Lagoon Blue is a perfect blend of heritage, versatility, and contemporary elegance.
