What I'm asked about the Zenith El Primero 03.2050.4035/21.C714
What strap size does the Zenith El Primero 03.2050.4035/21.C714 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 Zenith El Primero 03.2050.4035/21.C714 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.
