What I'm asked about the Omega Seamaster 300 234.10.39.20.01.001

What strap size does the Omega Seamaster 300 234.10.39.20.01.001 take?

The Omega Seamaster 300 234.10.39.20.01.001 needs 19 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 300 234.10.39.20.01.001 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 Seamaster 300 234.10.39.20.01.001?

Yes, in 19 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 39 mm diver I go for a full-thickness strap, not a thin one. I don't keep rubber ready in 19 mm: write to me and I'll make it.

Which strap do you recommend for the Omega Seamaster 300 234.10.39.20.01.001?

Rubber if you wear it in the water; otherwise a 19 mm calf strap, full thickness. You'll find it ready in the 19 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
