Strap for Carrera Date 36 Stainless Steel / Silver - Diamond

The TAG Heuer Carrera WBN231B.BA0001 features a 20-millimetre lug width. This measurement represents the orthogonal distance between the two attachment pins where the strap connects to the case. Measuring this correctly with a digital calliper is essential to prevent purchasing errors and ensure flawless strap fitment.

The ideal strap depends on your intended use. For daily professional wear, we recommend natural alligator with vegetable tanning, which ages beautifully. For sports and casual contexts, a cotton Jacquard NATO with satin steel buckle maintains the racing heritage. A waffle-textured rubber strap is perfect for weekends. The critical factor is selecting a 20mm strap with precisely engineered lugs and a material that complements the Carrera's refined, lightweight character.

Strap replacement involves gently removing the spring bars from the lugs. Use a dedicated spring bar tool to prevent scratches. Position the upper bar in the small release hole on the inner lug, then extract outward carefully. Repeat on the opposite lug. Insert the new strap by aligning the bars in their sockets and verify they are fully seated before wearing the watch.

Yes, provided the strap is engineered for 20mm lug width. Quality aftermarket straps offer complete mechanical compatibility and often exceed the original strap in design sophistication and craftsmanship. Milano Straps supplies verified 20mm straps for the WBN231B, customisable in material, colour, and stitch thread, with the option of bespoke production at Casati Milano atelier.

A premium leather strap—alligator, calf, or shell cordovan—typically lasts 2–4 years with daily wear, depending on usage intensity and climate conditions. Vegetable-tanned leather develops a richer patina over time. Rubber straps generally endure 3–5 years. Casati Milano provides an 18-month warranty and offers maintenance replacements at reasonable cost. Longevity increases considerably with occasional wear and proper storage in a dry environment.
