Strap for Williams Engine Date 42 Stainless Steel / Rubber

The lug width is 24mm. Measurement is taken from the inner shoulder of one lug seat to the other, perpendicular to the watch case plane. This specification is critical for ordering compatible straps and avoiding mounting errors.

Choice depends on intended use. For formal elegance: brown or black alligator with vegetable tanning. For daily versatility: vegetable-tanned calf in grey, cognac, or black. For sports and water: polyamide NATO or FKM rubber. Select based on primary wear context and your maintenance preferences.

Use a spring bar tool or sturdy toothpick. Insert the tool into the small lateral slot of the lug seat, lift gently to release the internal spring. Remove the old strap, align the new strap ends with both seats, and let the springs snap back. Do not force: movement should be fluid. If uncertain, consult an authorised watch retailer.

Yes, provided it has exactly 24mm lug width. Our Milano Straps designs are engineered for this specification and tested for fit. Always verify the strap is manufactured for 24mm to avoid overlaps or gaps. Any leather, NATO, or rubber strap in 24mm is compatible.

A quality leather strap (alligatore, vegetable-tanned calf) lasts 18–36 months with daily wear and proper care. Sun exposure, humidity, and perspiration reduce lifespan. Vegetable-tanned leather softens over time and develops patina, remaining functional beyond 24 months with care. NATO straps last 5–8 years. FKM rubber resists 3–4 years before stiffening.
