What I'm asked about the Blancpain Fifty Fathoms 5100-1127-NAH
What strap size does the Blancpain Fifty Fathoms 5100-1127-NAH take?
The Blancpain Fifty Fathoms 5100-1127-NAH needs 20 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Blancpain Fifty Fathoms 5100-1127-NAH 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-NAH?
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-NAH?
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.
