Strap for TAG Heuer Formula 1 Chronograph X Mario Kart Limited Edition

The lug width of the TAG Heuer Formula 1 CAZ201E.FC6517 is 20 millimetres. This measurement refers to the distance between the case lugs and determines compatibility with aftermarket straps. Verification before purchase is essential to avoid fitting errors.

For this 44-millimetre chronograph with ceramic and steel case, we recommend black alligator straps for elegance, vegetable-tanned calf for aesthetic evolution over time, or FKM rubber for aquatic performance. Choice depends on primary use and desired patina development. Casati Milano atelier customises bespoke straps with direct leather selection.

The procedure requires a spring bar removal tool. Position the watch on a stable surface, locate the lateral pins at the case lugs, gently introduce the tool's bifid end into the tension holes, compress the spring, and extract the pin. Repeat on the opposite side. Install the new strap by inserting the pins into the seat and verifying perfect alignment with the dial.

Yes, provided straps are specifically 20 millimetres in lug width. Any compatible aftermarket strap of this measurement fits perfectly. However, to maintain aesthetic proportions and collectible value, straps of equivalent quality to the case are recommended, such as vegetable-tanned leather or high-end technical rubber.

Durability depends on material and usage. An alligator or shell cordovan strap with vegetable tanning maintains structural integrity for 5–8 years with regular wear, developing noble patina. Standard calf lasts 3–5 years. FKM rubber resists degradation for 7–10 years without colour variation. Casati Milano atelier guarantees 18 months on custom straps and offers extended restoration and maintenance services.
