Integrated attachment: measurements, the most common questions, and the way to a made-to-measure strap.

Lug width to be confirmed

On this Tudor Black Bay One 79580-0007 the lug width doesn't convince me, and I don't want to give you a number I'm not sure about. Write to me on WhatsApp with the reference or a photo of the watch: I'll check it and tell you myself.

Frequently asked questions

How do you change the strap on a Tudor Black Bay One?

Strap replacement requires simple tools: a spring bar tool and a well-lit work surface. Position the watch with the case facing up, gently insert the spring bar tool between the lug and strap, pressing downward to compress the internal spring. Once the pin is freed, remove the old strap. To install the new one, align the holes with the pins, use the tool to compress the spring, and secure the strap at both ends.

How long does a leather strap last on a Tudor Black Bay One?

The lifespan of a leather strap depends on material quality and frequency of use. A high-quality leather such as alligator or shell cordovan maintains structural integrity for 5–10 years with regular maintenance (gentle cleaning and bi-annual conditioning). Vegetable-tanned leathers develop a natural patina that enhances aesthetics over time. Excessive moisture and prolonged sun exposure accelerate ageing. The 18-month warranty offered by Casati Milano on bespoke straps testifies to construction quality and expected durability.
