What I'm asked about the Breitling Exospace VB5510H1/BE45/245S/V20DSA.4
What strap size does the Breitling Exospace VB5510H1/BE45/245S/V20DSA.4 take?
The Breitling Exospace VB5510H1/BE45/245S/V20DSA.4 needs 24 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Breitling Exospace VB5510H1/BE45/245S/V20DSA.4 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 Breitling Exospace VB5510H1/BE45/245S/V20DSA.4?
Yes, in 24 mm leather. On a 46 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Breitling Exospace VB5510H1/BE45/245S/V20DSA.4?
A 24 mm calf strap, for every day. You'll find it ready in the 24 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
