Strap for Calibre 7 Twin Time Stainless Steel / Silver / Bracelet

The lug width of the TAG Heuer Carrera WAR2011.BA0723 is 20 millimetres. This dimension is measured between the inner shoulders of the two horizontal pins that connect the strap to the case. Compatible straps must measure exactly 20 mm in width to ensure proper insertion without force and without undesirable lateral play.

For the WAR2011.BA0723, we recommend a strap in African alligator of watchmaker quality or calf leather from vegetable tanning in dark brown tones. Alligator maintains regular texture and a patina that evolves over time, enhancing the elegance of the stainless steel case. Vegetable-tanned calf offers initial softness and natural aging that creates uniqueness. For sporting use, vulcanised natural rubber is the most robust and versatile choice.

Strap replacement is performed by removing the horizontal pins (spring bars) that attach the previous strap to the case lugs. Use a dedicated tool (spring bar tool) to push the pin from one side, releasing the tension of the internal spring. Extract the pin and the old strap, then insert the new strap aligning it with the lugs. Reinsert the pin ensuring that the springs lock correctly on both sides. The procedure requires precision to avoid damaging the lugs.

Yes, it is possible to use aftermarket compatible straps provided they respect the 20-millimetre lug width and are manufactured by qualified artisans. High-quality leather straps (alligator, cordovan, calf) maintain aesthetic coherence with the watch and can amplify the perceived value of the piece. Ensure that the strap has appropriate thickness and construction to support the weight and bulk of the 41 mm stainless steel case.

A quality leather strap has an average lifespan of 3-5 years with daily use and correct maintenance. Longevity depends on the material: alligator and cordovan, being denser leathers, can last up to 7-8 years; vegetable-tanned calf has an average life of 4-5 years. Exposure to moisture, perspiration and direct sunlight reduces lifespan. Rotation with other straps (rubber, NATO) significantly extends the life of each strap.
