Strap for Formula 1 Quartz Chronograph 37 Stainless Steel / Diamond / Pink MOP - Diamond / Bracelet

The TAG Heuer Formula 1 CAC1311.BA0852 features a 20-millimetre lug width. This measurement must be taken from centre to centre of the case lugs. It is a precise standard for mid-range Formula 1 sports models, and requires purpose-built straps to ensure correct fit and wrist security.

The choice depends on intended use: for formal elegance, we recommend dark brown or black alligator with vegetable tanning, which respects the design's clarity. For pure sportiness, a Cordura NATO in blue and white echoes the original vintage aesthetic. Vegetable-tanned calf leather offers the ideal compromise, developing a unique patina naturally over time.

The integrated lugs on the CAC1311.BA0852 require a spring bar tool to remove the 20-millimetre lateral pins. Place the watch on a soft pad, locate the lever in the pin groove, and gently push inward to free the lug from the case. Thread the new strap by inserting one pin first, then the other, until both click securely into place.

Absolutely. Any strap with a 20-millimetre lug width is compatible with the CAC1311.BA0852, provided the pin section matches and the material is durable (alligator, calf, FKM rubber are ideal). Artisanal quality straps often exceed original specifications in finishing and longevity.

A quality artisanal alligator or vegetable-tanned calf strap lasts 3–5 years with daily wear. Natural ageing is part of the charm. To extend lifespan, avoid prolonged water immersion, dry thoroughly after accidental wetting, and rotate between multiple straps to allow the material to breathe and dry completely.
