Strap for Formula 1 Solargraph 38 Black Polylight / Black / Rubber

The lug width of the TAG Heuer Formula 1 WBY1117.FT8087 is 19mm. This is a precise dimension that requires straps specifically crafted for this model. Straps measuring 18mm or 20mm are not compatible. To measure correctly, observe the space between the two metal pins that attach the strap to the watch lugs: that distance is exactly 19mm.

The best strap depends on your usage and personal context. For daily professional wear: medium brown alligator or vegetable-tanned calf leather. For summer and sports: NATO textile strap in nautical grey or off-white. For those seeking luxury: shell cordovan or alligator with developed patina. All must feature a 19mm lug width to ensure perfect compatibility with the WBY1117.

The strap on the WBY1117 is changed by removing the two lateral pins that pass through the watch lugs. Use a dedicated spring bar tool to press the small pins and extract them from their housing. Once removed, the old strap falls free. To install the new strap, align the new strap's ends with the lug holes and insert the pins. Press until you hear the click of engagement.

Yes, absolutely. A 19mm aftermarket strap is fully compatible with the WBY1117.FT8087. The crucial requirement is that the lug width is correct and the strap is constructed from quality materials (natural leather, linen or polyester thread for NATO). Artisan straps in alligator, calf or shell cordovan often offer a level of customisation and quality superior to original factory TAG Heuer straps.

A natural leather strap with vegetable tanning, if worn daily, has an average lifespan of 3-5 years before replacement is required. Alligator and shell cordovan, being more resilient leathers, can last 5-7 years. Lifespan depends on friction with skin, ambient humidity and maintenance (avoid stagnant water, clean periodically). A NATO textile strap lasts 4-6 years. Casati Milano offers an 18-month warranty on all bespoke artisan straps.
