What I'm asked about the Frederique Constant Slim Line FC-306G4S6B2
What strap size does the Frederique Constant Slim Line FC-306G4S6B2 take?
For this reference I won't give you a size I'm not sure of yet. Send me a photo of the watch on WhatsApp: I'll recognise it and tell you how many millimetres you need.
Can the strap on the Frederique Constant Slim Line FC-306G4S6B2 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.
