Strap for Formula 1 Solargraph 38 Red Polylight / White / Rubber

The TAG Heuer Formula 1 WBY1161.FT8086 has a lug width of 19 millimetres. This is a non-standard measurement that requires specifically compatible straps. To verify accurately, measure the internal diameter between the two spring bar posts of the case using a digital calliper; do not confuse this with the external case width.

The best choice depends on intended use. For formal contexts, we recommend natural alligator with contrasting stitching. For daily wear, vegetable-tanned leather or high-density rubber offer comfort and durability. For maximum versatility, a Cordura NATO strap allows style changes easily. All straps must have 19mm lugs.

Use an appropriate spring bar tool. Insert the tool into the slot of the bayonet-style spring mechanism located at the sides of the lug. Press gently towards the case centre to release the pin. Remove the old strap and insert the new one, aligning the spring bar with the two seats in the case. The procedure requires care to avoid scratching the case.

Yes. Milanostraps.it offers handcrafted 19mm straps in premium materials: alligator, vegetable-tanned leather, rubber and canvas. Each strap is customisable in length, initials and thread colour. Casati Milano atelier also creates bespoke pieces with direct consultation and 18-month warranty.

Durability depends on material and use patterns. A high-quality alligator or vegetable-tanned leather strap maintains structural integrity for 3–5 years of moderate daily wear. The leather develops patina and ages gracefully. In very humid environments or with intense sunlight exposure, lifespan reduces. A natural rubber strap resists for 2–3 years before replacement is necessary. Store the strap away from extreme heat sources.
