FAQ

What is the lug width of the Zenith Elite 18.2143.691/01.C498?

The lug width of the Zenith Elite 18.2143.691/01.C498 is 20mm. This measurement represents the distance between the two attachment pins of the strap. It is advisable to personally verify with a digital caliper before purchasing an aftermarket strap to ensure absolute compatibility.

Which strap is best suited for the Zenith Elite in rose gold 40mm?

For a rose gold Elite, we recommend cognac-toned alligator or medium brown vegetable-tanned leather for maximum elegance. Alligator enhances the warmth of the gold with fine texture, while leather develops a natural patina over time. For versatility, a dark gray cotton NATO offers a more casual alternative while maintaining proper proportions.

How do you correctly measure the lug width of a watch?

Lug width is measured by positioning a digital caliper perpendicular to the two attachment pins (lugs) and measuring the internal distance between them. Do not confuse lug width with overall strap width: for a 20mm lug width, the strap will typically be 18-19mm wide, leaving 0.5-1mm of lateral space on each side for comfortable fit.

Are aftermarket straps compatible with the Zenith Elite 18.2143.691/01.C498?

Yes, any strap with a standard 20mm attachment is compatible with the Elite 18.2143.691/01.C498. Milano Straps offers customizable 20mm artisan straps in various leathers, materials, and colors. For guaranteed compatibility and styling advice, the Casati Milano atelier creates bespoke straps with personal leather selection.

How long does a natural leather strap last on a wristwatch?

A high-quality leather strap (alligator or vegetable-tanned leather) typically lasts 3-5 years with daily use, developing natural patina and character. Durability depends on frequency of use, sun exposure, humidity, and tanning quality. Milano Straps guarantees 18 months on Casati Milano bespoke straps.
