What I'm asked about the Omega Seamaster Diver 300M 212.30.44.52.01.001
What strap size does the Omega Seamaster Diver 300M 212.30.44.52.01.001 take?
The Omega Seamaster Diver 300M 212.30.44.52.01.001 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 Seamaster Diver 300M 212.30.44.52.01.001 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 Diver 300M 212.30.44.52.01.001?
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 44 mm diver I go for a full-thickness strap, not a thin one.
Which strap do you recommend for the Omega Seamaster Diver 300M 212.30.44.52.01.001?
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.
