Strap for Speedmaster Professional Yellow Gold / Skeleton / Alligator / Jubilee

The lug width is 20mm. This is the Omega standard for the Speedmaster Moonwatch and all models in this reference series. The measurement is taken with a digital caliper between the lateral lugs of the case, excluding the pins themselves. Tolerance is ±0.2mm.

For 18k yellow gold, we recommend dark alligator (brown or black) for optimal visual contrast, or vegetable-tanned calf that develops a patina complementary to the case's aging. Black FKM Tropic rubber restores the original instrumental context. Anthracite grey shell cordovan is the premium option for those seeking minimalist authority.

The Moonwatch uses standard 20mm spring bars. Insert a spring bar tool under the lug, applying light pressure to retract the internal spring, then extract the pin from the case. Repeat on the opposite lug. Reverse the procedure to install the new strap. We recommend caution to avoid scratching the caseback.

Yes. Any strap with a 20mm lug width is compatible from a mechanical standpoint. Aesthetic compatibility and durability depend on construction quality: vegetable-tanned leather, alligator, professional rubber, and cordovan offer long-lasting performance. Avoid uncertified synthetic straps, which rapidly compromise buckle reversibility.

A high-quality leather strap (alligator, vegetable-tanned calf, cordovan) typically lasts 4-6 years with moderate daily wear. Lifespan depends on exposure to moisture, frequency of use, and tanning quality. Casati Milano straps come with an 18-month warranty. Professional FKM Tropic rubber lasts 8-10 years.
