Tudor Black Bay

Having since expanded into an entire family of timepieces at various materials and sizes, the core Tudor Black Bay model is sized at 41mm, with cases predominantly in steel, and dive-scale bezel inserts made of anodized aluminum. Nowadays, these Black Bay 41mm models contain the in-house Tudor Caliber MT5602, which replaces the ETA calibers used in the very first ones. Most of the dials are matte black, with some notable exceptions, including the champagne-colored dials of the S&G (Steel and Gold) bi-material models.
