Strap for Formula 1 Calibre 5 37 Stainless Steel / Diamond / White - Diamond / Bracelet

The lug width of the TAG Heuer Formula 1 WAU2213.BA0861 is 20mm. This measurement represents the distance in millimetres between the spring bars connecting the case to the strap. It is essential to verify this dimension before purchasing an aftermarket strap, as a 19mm or 21mm lug width would not be compatible with this case.

For the Formula 1 WAU2213, straps in vegetable-tanned calf leather are recommended, as they develop a rich patina over time and maintain the sporty aesthetic, or vulcanised rubber for extreme conditions. Alligator is a premium option that imparts sophisticated elegance. The choice depends on intended use: rubber for saline or sporting environments, calf leather for daily balance, alligator for more formal occasions.

Strap replacement is performed using a dedicated tool (spring bar tool) to remove the pins from the lug holes. Position the tool in the pin's groove, apply gentle pressure, and extract the pin. Next, insert the pin into the new strap and reinsert it into the case lugs. Do not force to avoid damaging the case or eyelet holes.

Yes, any strap with a 20mm lug width is compatible with the WAU2213.BA0861.

A high-quality artisanal leather strap, made with vegetable tanning, has an average lifespan of 3–5 years with daily use, depending on exposure to moisture, chlorine, and salt water. Vegetable-tanned leather develops character and patina over time, but requires regular drying after water contact. Premium straps, such as alligator, can last 7–10 years if properly maintained. A rubber strap typically lasts 5–7 years.
