FAQ

What is the exact lug width of the Limes Chyros U6017-LA1.3?

The lug width of the Limes Chyros U6017-LA1.3 is 20mm. This measurement is the decisive parameter for strap compatibility: any lug width narrower or wider will not fit the mounting holes. To verify, measure the distance between the two holes of the left lug with a ruler positioned perpendicularly; the value must be exactly 20.0mm.

Which strap pairs best with the Limes Chyros U6017-LA1.3?

The choice depends on the dial finish and use case. For formal elegance, alligator in dark moro tone or calf leather in warm cognac shades create balanced visual proportions with the 43mm case. For contemporary versatility, NATO-style nylon interwoven straps in dark grey or navy blue offer lightness and chromatic flexibility. For sports or humid environments, FKM (Viton) rubber ensures durability without degradation. The mass of the Chyros case requires a strap with sufficient body: avoid exotic skins that are excessively thin.

How do I change the strap on the Limes Chyros U6017-LA1.3?

Remove the watch from your wrist. Position the case on a soft pad (felt or soft cloth) with the dial facing downward. Using a spring bar tool, press lightly inward one of the lug pins, creating space to extract the spring. Pull the old strap outward; the spring will loosen and you can fully remove the pin. Repeat on the other side. Reverse the process to apply the new strap, ensuring the pin is fully seated in the hole.

Which aftermarket straps are compatible with the Limes Chyros U6017-LA1.3?

Any strap with a 20mm lug width is compatible. You can choose from full leather (alligator, calf, veneer), NATO-style nylon or mixed-textile straps, and FKM (Viton) rubber for technical contexts. Always verify the exact lug width before purchase. Milano Straps offers a specialised selection of 20mm straps with lug finishing designed not to damage the stainless steel lugs of the case.

How long does a leather strap last on the Limes Chyros U6017-LA1.3?

A quality leather strap (alligator, calf with vegetable tanning) typically lasts 3–5 years with regular wear (4–5 times per week), increasing to 7–8 years if worn occasionally. Durability depends on ambient humidity, sun exposure, and care. Failure typically occurs at the point of maximum flexion (lug-to-body angle) or at the buckle-fastening loop. Nylon NATO straps offer superior durability (5–8 years even under heavy use). FKM (Viton) rubber remains stable for 4–6 years before showing signs of hardening.
