What I'm asked about the Blancpain Fifty Fathoms 5785F-11D03-63A

What strap size does the Blancpain Fifty Fathoms 5785F-11D03-63A take?

The Blancpain Fifty Fathoms 5785F-11D03-63A needs 23 mm between the lugs. It's the size I've been fitting on it for years.

Can the strap on the Blancpain Fifty Fathoms 5785F-11D03-63A 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 5785F-11D03-63A?

Yes, in 23 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 45 mm diver I go for a full-thickness strap, not a thin one. I don't keep rubber ready in 23 mm: write to me and I'll make it.

Which strap do you recommend for the Blancpain Fifty Fathoms 5785F-11D03-63A?

Rubber if you wear it in the water; otherwise a 23 mm calf strap, full thickness. I don't keep this size ready in the catalogue: I make it to measure. If you'd rather have something built on your wrist, the Casati atelier.
