Frequently asked questions
What is the lug width of the Omega Speedmaster 3559.32.00?
The Omega Speedmaster 3559.32.00 has a lug width of 20mm. This width is standard for many Omega chronograph models and can be easily verified by measuring with a digital caliper the distance between the case lugs where the strap attaches.
What is the best strap for the Omega Speedmaster 3559.32.00?
The best strap depends on use and personal style. Vegetable-tanned alligator offers sophisticated elegance, natural grain calf guarantees durability and evolving patina, shell cordovan is nearly indestructible and suited for those seeking conscious sportiness. A bespoke artisanal strap created by Casati Milano ensures solid construction and no slipping during daily wear.
How do you change the strap on the Omega Speedmaster 3559.32.00?
The strap is changed by extracting the lateral pins that connect the strap to the case. Use a spring bar tool (L-shaped tool with thin blade) to compress the internal spring of the pin, then slide the pin outward. Insert the new strap by aligning the holes and reinsert the pins. Work gently to avoid scratching the steel case.
Are aftermarket straps compatible with the Omega Speedmaster 3559.32.00?
Yes, any strap with a 20mm lug width is physically compatible. However, only high-quality artisanal straps guarantee solid construction, absence of slipping, and correct proportion with the case. Mass-produced straps tend to fail after a few months of moderate daily use. MilanoStraps offers a selection of ready-made 20mm straps and bespoke service via Casati Milano.
How long does a leather strap last on the Omega Speedmaster 3559.32.00?
Durability depends on material and usage. Alligator or vegetable-tanned calf, if cared for and not exposed to prolonged direct sunlight, lasts 3-5 years with moderate daily use. Shell cordovan resists for 7-8 years or beyond thanks to its natural fibrous structure. Artisanal straps from Casati Milano include an 18-month warranty against manufacturing defects and anomalous wear.
