Strap for Carrera Automatic Stainless Steel / Blue / Bracelet

The lug width of the TAG Heuer Carrera WBN2112.BA0639 is 21mm. This measurement corresponds to the distance between the centre points of the two metal pins protruding from the case. Precise measurement is essential before ordering a bespoke strap, as even minor variations will result in straps that do not fit correctly or remain loose during installation.

The ideal strap depends on usage and aesthetic preference. Satin-finished black alligator maintains the dial's austerity and offers discreet elegance. Vegetable-tanned calf in cognac introduces warmth and develops natural patina over time. For a sporty aesthetic, select satured NATO textile or FKM rubber straps. Shell cordovan provides superior hardness and develops a shine with wear. All materials are fully compatible with the 39mm stainless steel case.

To change the strap, use a small tool (spring bar tool) to extract the metal pins connecting the lugs to the case. Insert the flat tip of the tool into the pin's slot, lift gently, and the strap will be released. For the new strap, align the internal passant (width 19-20mm) with the pin and reinsert with steady pressure until it clicks into place. Avoid forcing to prevent case damage.

Yes, aftermarket straps are completely compatible provided they respect the 21mm lug width. Bespoke straps from Casati Milano are constructed with ±0.5mm tolerance for precision. Always verify that the internal passant is calibrated between 19-20mm for correct installation without lateral play or mechanical stress on the case.

Strap longevity depends on material and usage. Alligator and shell cordovan guarantee 5-7 years of daily wear due to their crystalline density. Vegetable-tanned calf lasts 4-5 years, developing visible patina over time. Vegetable-tanned straps age elegantly, meaning wear marks become part of the aesthetic character. FKM rubber straps maintain mechanical properties for 3-4 years before elasticity diminishes.
