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

The lug width (also called ansa width) of the TAG Heuer Carrera WAR2010.BA0723 is 20 mm. This is the distance measured between the inside edges of the two lateral lugs on the case. A compatible strap must be 20 mm wide to fit securely without risk of slippage or undue mechanical stress.

The ideal material depends on usage and personal taste. For formal elegance, alligator or vegetable-tanned calf leather offers refined finish and develops rich patina over time. For daily sporting use, FKM (Viton) rubber resists moisture and chlorine. Shell cordovan strikes a balance between elegance and sportiness, acquiring deep patina through natural ageing.

Strap replacement requires a spring bar tool and careful technique: place the watch on a soft surface, locate the two lateral holes housing the fixed pins, insert the tool into the lower hole to compress the internal spring, extract the pin, repeat on the other side. The pins on the WAR2010.BA0723 are typically 1.8 mm and must click firmly when reinserted.

Yes, provided the aftermarket strap is dimensioned to 20 mm lug width. High-quality straps made from vegetable-tanned leather, technical rubber, or technical fabric are fully compatible with the WAR2010.BA0723 and often offer greater aesthetic variety than official straps. Always verify the lug width specification before purchase.

A high-quality natural leather strap, if properly cared for (avoiding prolonged sun and moisture exposure), lasts 3–5 years with moderate daily wear. With intensive use and humid conditions, longevity reduces to 18–24 months. Regular preventive treatments with natural oils (mink oil or lanolin) extend lifespan. Milano Straps artisanal straps include an 18-month guarantee against manufacturing defects.
