Strap for Tudor Black Bay 79230DK

The Tudor Black Bay 79230DK features a 22mm lug width, which is the distance between the lugs of the case where the spring bars are positioned. This width is standard for this reference and allows the use of aftermarket straps specifically designed for 22mm, ensuring compatibility and secure assembly.

The choice depends on your intended use. For formal elegance and everyday versatility, black alligator in tight grain remains the most sophisticated solution. For frequent diving, a technically-advanced rubber strap offers superior grip and salt-water resistance. For those seeking a balance between practicality and character, vegetable-tanned leather develops natural patina over time, acquiring aesthetic personality.

Changing the strap requires a dedicated spring bar tool: insert the small lever into the lateral slot of the spring bar to compress the internal spring. Once extracted, the spring bar slides out and you can remove the old strap. Insert the new strap by aligning the holes and reinserting the spring bar until you hear the security click. If you lack the tool, seek professional service.

Yes, all straps with 22mm lug width are compatible with the Black Bay 79230DK. Compatibility is guaranteed by the standardisation of lug width and hole thickness. However, ensure the strap is designed for five spring bars (as the Tudor original) and that the passing end is properly sized to slide smoothly on the wrist.

A quality leather strap, whether vegetable-tanned or alligator, lasts between 3 and 8 years with daily wear, depending on humidity exposure, sunlight and mechanical wear. Leather treated using traditional methods tends to age better, developing patina rather than disintegrating. To extend longevity, avoid prolonged immersion in salt water and occasionally apply protective products specifically formulated for watch leather.
