Strap for Heritage Black Bay Red Manufacture / Strap

The lug width of the Tudor Black Bay 79230R-0005 is 22 mm. This measurement refers to the distance between the two spring bars that attach the strap to the case. You can verify this yourself by removing the current strap and measuring the distance between the pin holes using a digital calliper. This specification is essential for ensuring compatibility with any aftermarket strap.

The optimal strap choice depends on your lifestyle and aesthetic preferences. For formal elegance, we recommend vegetable-tanned alligator in cognac brown or black, which enhances sophistication whilst maintaining the tool watch character. For daily practicality, soft chromium-tanned leather offers versatility. For water-intensive environments or high humidity, vulcanised rubber provides complete water resistance. For robustness and colour variety, recycled-fibre NATO offers an ecologically conscious solution. Each material communicates a different intended use for your timepiece.

To change the strap, follow these steps: (1) place the watch on a soft surface; (2) locate the two lateral pins securing the strap; (3) using a spring bar tool, press downward on each pin to release the strap from the lug; (4) repeat on the other side; (5) remove the old strap; (6) insert the new 22 mm strap pins into the lateral slots on the case until they click into place. This operation requires precision but is straightforward. Should you need assistance, our Casati Milano atelier offers this service by appointment.

All straps with a 22 mm lug width are compatible. Our online collection includes alligator, calf leather, shell cordovan, textile NATO, and rubber options in numerous colour variations.

The lifespan of a natural leather strap depends on frequency of use, maintenance, and tanning quality. A vegetable-tanned alligator or calf strap, with proper care, typically lasts 3–5 years. The leather develops a natural patina over time, enhancing its aesthetic value. To maximise longevity: avoid prolonged saltwater exposure, clean regularly with a dry cloth, store in well-ventilated spaces, and apply a protective balm every six months. Our Casati Milano atelier offers restoration and regeneration services for worn straps, significantly extending their useful life.
