What I'm asked about the Zenith El Primero 03.2530.4047/78.M2530

What strap size does the Zenith El Primero 03.2530.4047/78.M2530 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 03.2530.4047/78.M2530 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.

The next step

The right strap isn't chosen. It is built, together.

From the atelier appointment to delivery, every step is made for those who know that things done well take time. Rare leathers, one piece at a time, eighteen months of warranty.
