The Formula 1 WBY1160.FT8085, seen from the bench

The TAG Heuer Formula 1 WBY1160.FT8085 is the contemporary evolution of a model born in 1986, transferring Formula 1 paddock timekeeping to enthusiasts' wrists. The stainless steel case with polyamide inserts (material used in drivers' fire-resistant suits) delivers technical character rarely found in contemporary sports watches. This 38mm diameter case, paired with a 19mm lug width, balances visual presence and wearability. The watch is powered by the TAG Heuer TH50-00 automatic caliber, COSC-certified chronometer movement with hour, minute, second and date display. Water-resistant to 300 meters.

Frequently asked questions

What is the lug width of the TAG Heuer Formula 1 WBY1160.FT8085?

The lug width of the TAG Heuer Formula 1 WBY1160.FT8085 is 19mm. This measurement is specific to this model and is determined by the distance between the two lugs of the case. It is essential to verify this measurement using a digital calliper before purchasing an aftermarket strap to ensure proper fitting and engagement of the spring bar mechanism.

Which type of strap is most suitable for the TAG Heuer Formula 1 WBY1160.FT8085?

The TAG Heuer Formula 1 WBY1160.FT8085 is best complemented by fine-grained black alligator straps, aged vegetable-tanned calf leather, or heavyweight cotton NATO fabric. Alligator delivers elegance whilst maintaining sporting austerity, calf leather permits mature patina development and personal colour variations, whilst NATO fabric recreates paddock heritage with historical continuity. FKM rubber is ideal for intensive aquatic use.

How do I change the strap on the TAG Heuer Formula 1 WBY1160.FT8085?

Position the watch on a dedicated holder with the case facing downward. Use a spring bar tool with dual ends to gently press the metal pin inward, releasing the lug from one side. Repeat on the opposite side. The lug width is 19mm, so ensure the replacement strap is correctly dimensioned for this measurement. Exercise gentle pressure to avoid scratching the case.

Is an aftermarket 19mm strap fully compatible with the WBY1160.FT8085?

Yes, a properly manufactured 19mm aftermarket strap is fully compatible with the WBY1160.FT8085, provided it meets professional quality standards. Milano Straps produces 19mm straps with millimetre-precision tolerances and tests spring bar fitting. Compatibility is equally assured with bespoke custom straps from the Casati Milano atelier.

What is the typical lifespan of a leather strap for the TAG Heuer Formula 1 WBY1160.FT8085?

A quality leather strap (alligator, vegetable-tanned calf, shell cordovan) for the WBY1160.FT8085 typically lasts 3–5 years with regular wear (4–5 days weekly). Longevity depends on tanning method, exposure to moisture and perspiration, and maintenance practices. Vegetable-tanned straps age beautifully, developing patina and extending the aesthetic life of the piece. Milano Straps provides an 18-month warranty covering manufacturing defects.
