Strap for Speedmaster Co-Axial 38 Stainless Steel / Diamond / MOP / Strap

The lug width of this model is 18mm. It is a precise dimension that corresponds to Omega's vintage standard. Always verify that your strap is exactly 18mm to avoid play or forcing. This measurement is fundamental to ensure wearing security and strap longevity.

It depends on use and personal preferences. Black alligator enhances the contrast of the black dial and offers formal elegance. Aged shell cordovan guarantees decade-long longevity and autobiographical patina. Vegetable-tanned calf leather is a compromise between elegance and daily practicality. Rubber is ideal for sporty use. All compatible with 18mm.

The strap is fixed through two lugs: use a dedicated tool (spring bar tool) to compress the elastic pin and extract the old strap from the lugs. Align the holes of the new 18mm strap, insert the elastic pin from one side, compress and lock the other end. Verify that the strap is centered and that there is no lateral movement before wearing the watch.

Yes, completely. All 18mm straps from milanostraps are handcrafted and compatible with the Omega Speedmaster Non-Moonwatch. You can customize the leather model (alligator, shell cordovan, calf), color, measurements, and stitching. The Casati Milano atelier also offers bespoke service with WhatsApp consultation.

A quality alligator strap lasts 5-7 years with daily use and proper maintenance (occasional cleaning, drying after humidity exposure). Shell cordovan with vegetable tanning exceeds 10-12 years. Vegetable calf resists 6-8 years. FKM rubber lasts over 10 years. Longevity depends on frequency of use, climate, skin perspiration, and personal care. A neutral leather balm preserves hydration and elasticity.
