Strap for Tudor Black Bay 58 79030B

The lug width of the Tudor Black Bay 58 (reference 79030B) is 20 millimetres. This dimension represents the internal distance between the two lateral attachment lugs. It is essential to verify this measurement before ordering an aftermarket strap, as an incorrect width (for example 22mm) would create dangerous play between the strap and case, whilst a smaller width (18mm) would not fit into the Tudor lugs at all.

The choice of strap depends on intended use and personal aesthetics. For formal elegance, polished black alligator delivers minimalist sophistication. For versatile classicism, cognac-brown alligator or vegetable-tanned calf in dark grey ensure supple hand-feel and humidity resistance. For frequent diving, vulcanised rubber or NATO fabric straps provide superior practicality and grip. Oxblood shell cordovan develops a fascinating patina over time that mirrors the behaviour of the brushed case finish.

Strap replacement is a straightforward operation: obtain a spring bar removal tool and position the watch on a soft surface with the lug side facing upwards. Insert the spring bar tool into the lateral groove of the attachment lug, apply gentle pressure to compress the internal spring, and extract the pin. Repeat on the opposite side. Insert the new pins through the strap, align them with the case lugs, and press firmly until you hear or feel the safety click of the spring. Verify that the strap is securely fastened before wearing the watch.

Yes, the 79030B accepts aftermarket straps provided they respect the 20-millimetre lug width and feature standard attachment lugs with 1.8-millimetre diameter pins. High-quality artisanal straps in alligator, calf, shell cordovan and rubber are fully compatible. Ensure that the strap is constructed to precision standards, as the tolerance space between the brushed case and strap is restricted.

The lifespan of a natural leather strap depends on usage intensity, care and construction quality. Premium-grade calf or alligator, with robust stitching, typically lasts 3–5 years in moderate daily use. Frequent water exposure (diving, swimming) shortens lifespan. Shell cordovan resists longer, up to 7–10 years, whilst developing a fascinating patina. Vulcanised rubber straps have similar durability but require minimal maintenance. Strap repair is always possible through specialised craftspeople.
