What I'm asked about the Blancpain Fifty Fathoms 5100-1127-NAJ

What strap size does the Blancpain Fifty Fathoms 5100-1127-NAJ take?

The Blancpain Fifty Fathoms 5100-1127-NAJ 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 Blancpain Fifty Fathoms 5100-1127-NAJ 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 Blancpain Fifty Fathoms 5100-1127-NAJ?

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 38 mm diver I go for a full-thickness strap, not a thin one.

Which strap do you recommend for the Blancpain Fifty Fathoms 5100-1127-NAJ?

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.
