Frequently asked questions
What is the lug width of the Omega Speedmaster (Non-Moonwatch) 326.32.40.50.06.001?
The lug width is 19mm. This is the distance between the lugs of the case and is critical for strap compatibility. Do not confuse with 20mm Speedmaster models: the 326.32.40.50.06.001 specifically requires 19mm straps for a precise fit.
What strap material do you recommend for the Speedmaster 326.32.40.50.06.001?
We recommend black or dark brown alligator for a formal racing aesthetic, shell cordovan for a patina that evolves over time, or vegetable-tanned calf for softer elegance. If you wear the watch daily in humid environments, slate grey FKM rubber offers practicality without sacrificing aesthetics.
How do I correctly measure the lug width of my Omega Speedmaster?
Remove the current strap (or observe the lugs). Using a digital caliper, measure the internal distance between the two lugs that secure the strap to the case. This measurement, expressed in millimeters, is the lug width. For the 326.32.40.50.06.001, it should be 19mm. Measuring from the outer edge of the lugs is not correct.
Are milanostraps.it straps compatible with my Speedmaster 326.32.40.50.06.001?
Yes, provided you select the 19mm strap category. All our straps for 19mm lug width are compatible with this Omega reference. You can order online or contact the Casati Milano atelier for a bespoke version with custom leather and finishes.
How long does a leather strap last on a Speedmaster I wear daily?
A quality leather strap (alligator, shell cordovan, premium calf) lasts 3-5 years with daily wear, depending on frequency of use, climate, and maintenance. FKM rubber has similar durability but different degradation. The Casati Milano atelier offers an 18-month warranty on bespoke straps and support for extension in case of natural wear.
