Strap for Heritage Black Bay Black S&G / Stainless Steel / Yellow Gold / Champagne / Bracelet

The Tudor Black Bay 79733N-0004 features a lug width of 22mm, measured as the distance between the lugs (spring bar holders) where the strap attaches to the case. This specification is critical for ensuring aftermarket strap compatibility. You can verify the measurement using a digital calliper by measuring the inner distance between both lugs, or refer to Tudor's official documentation. Milano Straps maintains a curated selection of 22mm straps specifically tested for this model.

The optimal strap choice depends on your personal style and intended use. For aesthetic balance and versatility, alligator leather in vegetable tanning with a Havana brown finish is the ideal choice: the irregular grain and developing patina naturally complement the yellow gold 18k case. For formal elegance, anilined calf leather in cognac tone offers uniform surface and refined appearance. For sportive practicality, NATO webbing or FKM rubber in black maintains the model's technical profile while permitting rapid replacement.

To change the strap on the 79733N-0004, you will need a spring bar tool or dedicated lever. Position the strap on a soft support surface, then insert the tool into one of the two lugs to compress the internal spring: once the spring yields, extract the lug pin from its hole. Repeat for the second lug, then remove the strap. For installation, align the new strap's lugs with the case holes and press until you hear a click. If unfamiliar with this procedure, Casati Milano atelier provides professional strap-change service with personalised consultation.

Yes, any 22mm strap is compatible with the 79733N-0004, provided the spring bars are functional and correctly sized. Compatibility is determined strictly by lug width, not by strap brand. Milano Straps offers a comprehensive range of 22mm straps in alligator, calf, shell cordovan, NATO and FKM rubber, all tested and verified. Personalisation in sizing, colours and finishes allows you to tailor the strap to your aesthetic and functional preferences.

The lifespan of a natural leather strap depends on tanning quality, intensity of use and maintenance practices. Premium alligator or calf leather in vegetable tanning, with moderate daily wear, maintains structural and aesthetic integrity for 2-4 years whilst developing a distinctive patina over time. Prolonged exposure to saltwater, excessive humidity and UV radiation accelerates ageing. FKM rubber and woven NATO offer greater resilience in humid environments and aquatic activities. Milano Straps offers an 18-month warranty on bespoke straps, with servicing and replacement available through Casati Milano atelier.
