What I'm asked about the Omega Seamaster Diver 300M 212.30.36.20.01.002

What strap size does the Omega Seamaster Diver 300M 212.30.36.20.01.002 take?

The Omega Seamaster Diver 300M 212.30.36.20.01.002 needs 18 mm between the lugs. It's the size I've been fitting on it for years.

Can the strap on the Omega Seamaster Diver 300M 212.30.36.20.01.002 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 212.30.36.20.01.002?

Yes, in 18 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 36 mm diver I go for a full-thickness strap, not a thin one. I don't keep rubber ready in 18 mm: write to me and I'll make it.

Which strap do you recommend for the Omega Seamaster Diver 300M 212.30.36.20.01.002?

Rubber if you wear it in the water; otherwise a 18 mm calf strap, full thickness. You'll find it ready in the 18 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
