What I'm asked about the Omega Speedmaster Moonwatch 311.90.42.30.01.001
What strap size does the Omega Speedmaster Moonwatch 311.90.42.30.01.001 take?
The Omega Speedmaster Moonwatch 311.90.42.30.01.001 needs 20 mm between the lugs, usually 16 mm at the buckle. It's the size I've been fitting on it for years.
Can the strap on the Omega Speedmaster Moonwatch 311.90.42.30.01.001 be changed?
Yes. It has spring bars between the lugs: with the right tool the strap comes off in a minute. If you'd rather not risk a scratch, I do it in the workshop.
Can I put a leather strap on the Omega Speedmaster Moonwatch 311.90.42.30.01.001?
Yes, in 20 mm leather. On a 42 mm chronograph I like box calf: it holds its shape and carries a substantial case.
Which strap do you recommend for the Omega Speedmaster Moonwatch 311.90.42.30.01.001?
A 20 mm box calf. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.

Frequently asked questions
What is the best strap for the Omega Speedmaster Moonwatch platinum 311.90.42.30.01.001?
For the platinum Moonwatch we recommend alligator with fine grain for visual contrast, vegetable-tanned calf dyed navy blue for daily versatility, or shell cordovan for those wishing to acquire historical patina over time. The choice depends on the intended use: pure formal, dressy-casual, or competition.
Is the Moonwatch 311.90.42.30.01.001 strap compatible with other Omega models?
No. Although many Omega watches use the 20mm lug width, the specific geometry of the Moonwatch lugs (curves, depth, distance) makes it advisable to use straps tested specifically for the 311.90.42.30.01.001. Generic 20mm straps may not fit correctly.
How long does a leather strap last on the Omega Speedmaster Moonwatch?
The lifespan of a leather strap varies based on material: French alligator lasts 3-5 years with daily wear; vegetable-tanned calf 2-3 years; shell cordovan 5-7 years thanks to fiber density. Frequency of wear, contact with sweat, water and sunlight accelerate aging. Casati Milano guarantees its artisanal straps for 18 months.
