What I'm asked about the Omega Seamaster Diver 300M 212.32.41.20.04.001

What strap size does the Omega Seamaster Diver 300M 212.32.41.20.04.001 take?

The Omega Seamaster Diver 300M 212.32.41.20.04.001 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 Seamaster Diver 300M 212.32.41.20.04.001 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 Seamaster Diver 300M 212.32.41.20.04.001?

Yes, in 20 mm leather, as long as you don't wear it in the water: leather doesn't like the sea or the pool. For days in the water, rubber. On a 41 mm diver I go for a full-thickness strap, not a thin one.

Which strap do you recommend for the Omega Seamaster Diver 300M 212.32.41.20.04.001?

Rubber if you wear it in the water; otherwise a 20 mm calf strap, full thickness. 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

Is a third-party strap compatible with the 212.32.41.20.04.001?

Yes, any aftermarket strap with a 20mm lug width is completely compatible. Our handcrafted straps are specifically made for this measurement and guarantee a precise and secure fit with your Seamaster Commander case.

How long does a leather strap last on this watch?

A premium leather strap such as alligator or calf, with ordinary care (avoiding prolonged exposure to unrinsed salt water, direct sunlight and extreme humidity), maintains excellent appearance and functionality for 3-5 years. With regular maintenance and periodic treatments with specific creams, the lifespan extends further. Casati Milano straps include an 18-month warranty and can be regenerated or replaced with new personalised models.
