Strap for Formula 1 Alarm 42 Titanium PVD / Black / Rubber

The lug width of the TAG Heuer Formula 1 WAU111D.FT6024 is 20 millimetres. This measurement represents the distance between the two case lugs where the strap is attached. It is essential to measure this dimension accurately using a calliper or ruler, as even a 1-millimetre difference can prevent correct strap insertion into the lugs.

The best strap depends on your intended use. To maintain the original sporting character, we recommend straps in FKM rubber, Cordura canvas or thick nylon NATO. For a more refined aesthetic, a shell cordovan strap in burgundy or calf leather with alligator embossing creates an elegant contrast with the brushed titanium case. For everyday versatility, a strap in vegetable-tanned leather in cognac offers the finest balance between aesthetics and practicality.

To change the strap on the WAU111D.FT6024, use a spring bar remover tool. Position the tool's tip in the small slot of the spring that supports the strap, apply gentle inward pressure, then remove the spring. Repeat on the other side. Insert the new strap by aligning one end with the spring first, then press until the spring clicks into the opposite lug. Ensure the strap is securely fastened before wearing the watch.

Any strap with a 20-millimetre lug width is compatible with the WAU111D.FT6024. Milano Straps offers handcrafted straps in leather, rubber, fabric and NATO, all customisable in closure lengths, initials and stitching thread. Compatibility is guaranteed if the lug width is exactly 20 millimetres. Avoid straps of different widths (19 or 21 millimetres) as they may damage the case lugs.

The lifespan of a leather strap depends on frequency of wear, climate and maintenance level. A high-quality handcrafted leather strap, worn regularly (5–6 days per week), has an average life of 3–5 years before showing significant signs of wear. Vegetable-tanned leather ages elegantly, developing a characteristic patina. To extend durability, avoid prolonged exposure to water and direct sunlight, and occasionally apply a protective balm. Milano Straps offers an 18-month warranty on all bespoke straps created by Casati Milano.
