Frequently asked questions

What is the lug width of the Limes Chyros U6017-LA2.4?

The lug width of the Limes Chyros U6017-LA2.4 is exactly 20 millimetres. This dimension represents the precise distance between the two spring bar holes on the lugs and determines compatibility with all aftermarket straps. Always verify this measurement directly on the case before ordering a replacement strap.

Which type of strap is most suitable for the Chyros U6017-LA2.4?

The Chyros pairs exceptionally well with premium alligator or calf leather straps, which enhance the satin-finished steel case texture. For sports or maritime use, a heavy cotton NATO strap or FKM rubber strap offers practicality and durability. Your choice depends on the intended context: formal, daily wear, or active use.

How do I change the strap on this watch?

Strap replacement is performed via the spring bars seated in the lug holes. Use a dedicated spring bar remover tool to apply gentle pressure on the small buttons that secure the spring mechanism. Never force directly with unsuitable tools—you risk scratching the case. Once the old strap is removed, insert the new spring bars into the lug holes and confirm they click firmly into place.

What is the lifespan of a leather strap on the Chyros?

A high-quality natural leather strap, subject to moderate daily wear, has an average lifespan of 2–3 years before replacement becomes necessary. Longevity depends on usage intensity, ambient humidity, and maintenance: keep the strap dry and periodically apply a protective balm. The patina that develops over time is integral to the strap's beauty and does not indicate deterioration.

Can I use a 22mm strap on this watch?

No, a 22mm strap is not compatible with the Chyros U6017-LA2.4, which requires exactly 20mm lug width. An oversized strap would create visible gaps between the band and lugs, compromising both aesthetics and strap security. Always ensure exact lug width compatibility before purchasing a replacement strap.
