Strap for WilliamsF1 Team Skeleton Engine Date 40.5 Stainless Steel / Bracelet

The lug width of the Oris Williams 01 733 7560 4114-07 8 25 01 is exactly 22 millimetres. This means any replacement strap must measure 22 mm in width to fit correctly between the spring bars. Always verify the dimension before ordering an aftermarket strap to prevent compatibility issues.

We recommend a vegetable-tanned calf leather in cognac or dark brown, which balances the watch's racing aesthetic with formal versatility. Alternatively, black alligator adds refinement for evening wear. For daily sports use, a NATO strap in neutral tones or textured rubber maintains the model's motorsport heritage. Choose based on your dial colour and intended use.

Position the watch face-down on a soft surface with the lugs facing up. Use a spring bar tool to depress the spring bar pin, then slide out the old strap. Align the new 22mm strap with the lug holes, then release the spring bar. We recommend consulting a specialist if unfamiliar with the procedure to avoid case damage.

All straps with a 22 mm lug width are compatible. This includes leather options (calf, alligator, shell cordovan, vegetable-tanned), textile NATO straps, vulcanised rubber, and metal or ceramic bracelets. Always confirm the width is precisely 22 mm to ensure proper fitment without lateral movement.

Strap longevity depends on frequency of wear, climate, and tanning quality. A quality vegetable-tanned calf strap worn daily typically lasts 3–5 years before significant wear appears. Alligator and shell cordovan may reach 5–7 years. High humidity, perspiration, and direct sunlight accelerate deterioration. Regular cleaning and rotating multiple straps extends useful life considerably.
