Frequently asked questions

What is the lug width of the Limes Chyros U6017-LA2.1?

The lug width of the Limes Chyros U6017-LA2.1 is 20mm. This measurement refers to the distance between the pins on which the strap runs and determines compatibility with standard market straps. To verify correctly, measure the space between the case attachments, excluding the external shaping of the strap itself.

What is the best strap for the Limes Chyros U6017-LA2.1?

There is no universal choice—it depends on usage and desired aesthetics. An alligator leather with vegetable tanning is ideal for daily elegance and formal transitions. A high-density chrome-tanned calf offers softness and durability. A NATO guarantees versatility with affordable seasonal changes. An FKM rubber strap is perfect for technical and humid environments. We recommend consulting our craftsmen for the optimal choice based on your wrist and personal style.

How do I change the strap on the Limes Chyros U6017-LA2.1?

Position the watch on a soft surface with the caseback facing upwards. Locate the lateral pins that attach the strap to the case. Using a specialised spring bar tool, insert the forked tip under the pin, apply gentle downward pressure to compress the internal spring, then extract the pin completely. Repeat on both sides. Position the new strap and reinsert the pins, ensuring they click fully into place. If you lack experience, entrust this to a specialised watchmaker.

Can I use an aftermarket-compatible strap with the Limes Chyros U6017-LA2.1?

Yes, any strap with a 20mm lug width is mechanically compatible. However, for optimal aesthetic integration and guaranteed structural durability, we recommend straps specifically crafted for this configuration. Avoid generic straps that may present excessive play between the pin and internal spring, compromising wearing stability and the visual elegance of the overall piece.

How long does a leather strap last on a Limes Chyros U6017-LA2.1?

Longevity depends on material, frequency of use, and climate conditions. An alligator or vegetable-tanned calf, if treated with natural oils periodically, can last 4–6 years of daily wear. A chrome-tanned calf, more moisture-resistant, reaches 5–7 years. In humid or saline environments, durability reduces to 2–3 years. An FKM rubber strap maintains structural integrity for 8–10 years, degrading only gradually. We recommend seasonal rotation between different straps to extend overall longevity.
