What I'm asked about the Certina DS Action C048.407.44.041.00

What strap size does the Certina DS Action C048.407.44.041.00 take?

The Certina DS Action C048.407.44.041.00 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 Certina DS Action C048.407.44.041.00 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 Certina DS Action C048.407.44.041.00?

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 Certina DS Action C048.407.44.041.00?

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.
