What I'm asked about the Corum Bubble L390/03340
What strap size does the Corum Bubble L390/03340 take?
The Corum Bubble L390/03340 needs 27 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Corum Bubble L390/03340 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 Corum Bubble L390/03340?
Yes, in 27 mm leather. On a 52 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Corum Bubble L390/03340?
A 27 mm calf strap, for every day. 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.
