Frequently asked questions

What is the lug width of the TAG Heuer Formula 1 CAU1117.FT6024?

The TAG Heuer Formula 1 CAU1117.FT6024 features a lug width of 20mm. This dimension is a standard specification for contemporary sports chronographs and accommodates robust, versatile straps. To verify compatibility, check the gap between the case lugs: the strap must fit snugly without excessive lateral play.

Which strap is recommended for the TAG Heuer Formula 1 CAU1117.FT6024?

Your choice depends on intended use. For a formal-sporty aesthetic, natural alligator in black or dark brown is ideal. If you desire an elegant patina development, vegetable-tanned calf leather matures beautifully over time. For practicality and water resistance, technical rubber or silicone are excellent. For authentic sporting heritage, a military-grade NATO fabric emphasizes the watch's pilot-racing lineage.

How do I change the strap on the TAG Heuer Formula 1 CAU1117.FT6024?

To replace the 20mm strap, first remove the deployante (integrated clasp), then extract the spring bars connecting the strap to the case lugs using a dedicated tool. Align the new strap's holes with the bars, reinsert the deployante, and ensure the strap is secure but not constrictive. If unfamiliar with this procedure, the Casati Milano atelier offers professional replacement services.

Can I use an aftermarket-compatible strap with the TAG Heuer Formula 1 CAU1117.FT6024?

Absolutely. Any strap with a 20mm lug width is compatible with the CAU1117.FT6024. Milano Straps' artisanal straps are crafted from premium leather selections (alligator, calf, shell cordovan) and verified to fit the sport watch's lugs perfectly. We also offer personalisation in initials, bespoke dimensions, and custom thread colours.

How long does a leather strap last on a TAG Heuer Formula 1?

Leather strap longevity depends on tanning quality and usage patterns. Alligator or vegetable-tanned calf, with ordinary care (avoiding prolonged moisture, drying after water contact), typically lasts 3–5 years before significant wear. Shell cordovan, due to its natural density, can endure 7–8 years. Casati Milano guarantees 18 months on bespoke straps, covering manufacturing defects.
