Strap for Speedmaster Professional Missions Skylab 3

The Omega Speedmaster Professional 3597.23.00 has a lug width of 20 millimeters. This measurement is standard for this version of the Moonwatch and ensures balanced proportions on the wrist. To verify compatibility, measure the distance between the internal attachment points of the case: it must correspond to 20mm.

For the Speedmaster 3597.23.00 in brushed steel, we recommend black or dark brown dyed alligator for formality, shell cordovan for evolving patina, vegetable-tanned leather for sustainability, or rubber/nylon for tactical versatility. The choice depends on your use: formal, daily, or sports.

Use a spring bar tool to remove the spring bars from the case attachment points. Insert the tool tip into the lateral hole of the spring bar, lift slightly and slide the strap outward. Repeat on the other side. To mount the new strap, align the slots with the spring bars and push until you hear the fixing click.

All straps with 20mm lug width are compatible with the Speedmaster 3597.23.00. On milanostraps.it you will find a complete collection of artisanal 20mm straps, customizable in material, color and finish. We recommend always checking the total length to adapt it to your wrist.

A quality leather strap (alligator, shell cordovan or vegetable-tanned leather) typically lasts 3-5 years with daily use, developing natural patina over time. Durability depends on the tanning method, environmental humidity and frequency of use. Casati Milano straps include an 18-month warranty and are renewable through professional reconditioning.
