FAQ

What is the lug width of the Limes Chyros U6017-LA3.1?

The Limes Chyros U6017-LA3.1 features a lug width of 20mm. This dimension represents the space between the spring bar pins on the case lugs, and it is the critical parameter for aftermarket strap compatibility. Always verify this measurement before purchasing a replacement strap.

Which strap do you recommend for the Limes Chyros U6017-LA3.1?

The Chyros demands a conscientious material consultation. A natural alligator strap with vegetable tanning, in cognac or aged tobacco hues, amplifies the case geometry through directional grain patterning. A calf leather strap with coarse grain in black or charcoal-black offers a formal interpretation. For versatility, a NATO in robust cotton or a fluoroelastomer rubber strap transforms the watch into a more functional instrument. Your choice depends on intended use and desired aesthetic narrative.

How do I change the strap on the Limes Chyros U6017-LA3.1?

The Chyros utilises spring bar lugs of standard construction. To change the strap, obtain a spring bar removal tool. Position the tool in the small aperture at the base of each lug, apply gentle pressure to release the internal spring mechanism and extract the pin. Repeat for the opposite lug, then insert the new strap by aligning the spring bars into the lug holes. This operation requires precision and gentleness to avoid case damage.

Which aftermarket straps are compatible with the Limes Chyros U6017-LA3.1?

All straps with a 20mm lug width are compatible with the Chyros. Milano Straps offers a dedicated collection at this lug size: alligator leather, calf, shell cordovan, NATO in various textiles, and rubber straps. Always verify that the strap has been constructed with lugs that respect the 20mm specification, as not all aftermarket solutions guarantee construction precision.

How long does a leather strap last over time?

A leather strap's longevity depends on material quality, tanning method and daily usage patterns. An alligator strap with vegetable tanning, subjected to periodic maintenance (gentle cleaning and conditioning with neutral waxes), maintains structural integrity for 4–6 years of regular use. Lower-grade calf leather tends toward visible degradation within 2–3 years. The patina developed during natural ageing represents an aesthetic asset, transforming the strap into a personalised object over time. Longevity is a virtue, not a guarantee.
