Strap for Speedmaster Professional Moonwatch Apollo 17 45th Anniversary / Stainless Steel

The Omega Speedmaster Moonwatch reference 311.30.42.30.03.001 has a lug width of 20mm. This specification is essential when purchasing an aftermarket strap, as it determines compatibility with the spring bars and buckle. The width must match exactly: 20mm, not 18mm or 22mm.

The choice depends on your use. For historical authenticity, a grey or black nylon NATO replicates the original equipment; for elegance, a black or brown alligator with stainless steel deployant clasp enhances the ceramic case; for sports versatility, a rubber or rubber-silicone strap enables swimming and water activities. Premium materials such as shell cordovan age with a unique patina.

Remove the spring bars using a dedicated tool (spring bar tool) or contact a specialized atelier. Position the new strap on the case, aligning the bars with the lugs, and press gently until you hear the click. Do not force: the bar enters with gentle pressure. Casati Milano offers appointment-based assistance to ensure zero damage to the ceramic.

A quality leather strap (alligator, calf or shell cordovan) lasts 3–5 years with daily wear, subject to perspiration, light and humidity. Longevity depends on the tanning method: vegetable-tanned leathers age better, developing patina. A rubber or NATO strap lasts 5–7 years. Regular maintenance with neutral cleaners and air-drying extends lifespan up to double.
