The Zenith El Primero 18.2110.400/01.C498 features exactly 18 mm lugs, a dimension rooted in Zenith's 1970s tradition. To verify, remove the original strap and measure the distance between the inner edges of both lugs using a digital caliper.
What is the best strap for this Zenith chronograph?

How do I change the strap on the Zenith El Primero 18.2110.400/01.C498?

Can I use an aftermarket third-party strap on my Zenith?
Yes, provided it has exactly 18 mm lugs measured precisely between the inner edges. Verify that the finishes at the lug ends have no gaps or excessive tension. Milano Straps handcrafted straps are tested for compatibility with this reference.
