About this watch

The Tudor Heritage Black Bay Ceramic One for Only Watch is a masterpiece that combines style, functionality, and heritage in one stunning package. With its sleek black ceramic case and 41mm diameter, this watch exudes modern sophistication while being durable and lightweight due to its titanium, ceramic, and stainless steel construction. The PVD coating adds an extra layer of protection without compromising the sleek finish. At the heart of this timepiece is the Tudor caliber MT5602, a certified COSC automatic movement that beats at 4Hz, ensuring precision and reliability. With a power reserve of 70 hours, you can forget to wind it over the weekend and still expect it to tick away come Monday morning. This watch boasts an impressive water resistance of 200 meters, making it suitable for diving as well as everyday wear. The rotating bezel is functional and designed for divers, while the black dial with stick and dot indexes is easy to read in challenging lighting conditions. When you strap on this watch, you'll be pleasantly surprised by its comfort and weight. As a one-of-a-kind piece, it's not just a timepiece but also a piece of history, telling a story and having intrinsic value.
