What I'm asked about the Omega Seamaster 300 233.60.41.21.03.001
What strap size does the Omega Seamaster 300 233.60.41.21.03.001 take?
The Omega Seamaster 300 233.60.41.21.03.001 needs 21 mm between the lugs, usually 18 mm at the buckle. It's the size I've been fitting on it for years.
Can the strap on the Omega Seamaster 300 233.60.41.21.03.001 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 300 233.60.41.21.03.001?
Yes, in 21 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. I don't keep rubber ready in 21 mm: write to me and I'll make it.
Which strap do you recommend for the Omega Seamaster 300 233.60.41.21.03.001?
Rubber if you wear it in the water; otherwise a 21 mm calf strap, full thickness. You'll find it ready in the 21 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
