Strap for WilliamsF1 Team Skeleton Engine Date 42 Stainless Steel / Bracelet

The lug width of the Oris Williams 01 733 7613 4114-07 8 24 75 is precisely 20 millimetres. This dimension is standard for this reference and determines compatibility with all aftermarket straps. To measure correctly, insert a calliper between the lug attachments on the case and verify the internal distance: 20mm ensures perfect fit without lateral play.

It depends on usage and aesthetic preferences. For a sophisticated and durable choice, we recommend black alligator with vegetable tanning: the natural patina evolves over time in harmony with the case's steel patina. For pure sportiness, a ballistic nylon NATO offers ease of quick-change and solid construction. A calf leather with a satin-finished deployant clasp represents the ideal compromise between elegance and daily wearability. Burgundy shell cordovan is the most precious choice, ideal for elevating formal contexts.

The process is straightforward. Obtain a spring bar tool (small bar removal instrument). Position the watch with the strap facing upward, insert the tool's tip into the hole beneath the lug, apply gentle pressure to compress the internal spring, extract the bar and repeat on the opposite side. Mount the new strap by reversing the procedure. We recommend a professional if you lack experience.

All straps with a 20mm lug width are compatible. Milano Straps offers a dedicated collection of 20mm straps: vegetable-tanned leather, alligator, shell cordovan, NATO in various fabrics and technical rubber. Each strap is handcrafted in Italy and can be customised to fit your case perfectly.

Durability depends on leather quality and usage patterns. An alligator strap with vegetable tanning lasts 5-8 years under moderate daily wear. Vegan calf lasts 3-5 years. Calf tinted in cavaglione (without gilding) lasts 6-7 years. Technical rubber offers maximum durability (8-10 years) but less aesthetic evolution. Periodic maintenance with neutral balm significantly extends useful life.
