FAQ

What is the lug width of the Limes Endurance U8797B-LC2.1?

The lug width of the Limes Endurance U8797B-LC2.1 is 20.00 mm. This specific measurement requires a compatible 20 mm strap, which is not standardised in the mass market. Always verify the measurement with a ruler positioned perpendicularly to the lugs before purchase.

Which strap do you recommend for the Limes Endurance?

For the Limes Endurance U8797B-LC2.1, we recommend three categories. Vegetable-tanned alligator offers natural ageing and unique patina development over time. Shell cordovan provides immediate tactile response and superior water resistance. Structured calf leather (fine grain) maintains elegance and versatility. For sporty use, NATO and rubber straps remain ideal. The choice depends on your wearing context and personal aesthetic preference.

How do I change the strap on the Limes Endurance?

Locate the two mounting pins (also called suspension bars) at the ends of the case. Use a spring bar tool—a specialised implement with a flat tip—to gently compress the pin inward. The old strap will detach laterally. Insert the new strap by aligning the holes with the compressed pin, then release the pressure. Repeat at the other end. This is a straightforward operation, but we recommend caution to avoid scratching the case.

Is an aftermarket strap compatible with the U8797B-LC2.1?

Yes, provided the strap is specific to the 20 mm lug width. Not all aftermarket 20 mm straps are constructed with the same tolerance precision: verify that the thickness at the lug end is not excessive (the strap must fit comfortably between the case and the lugs) and that the closure (standard buckle or deployante) does not excessively reduce the total bracelet length.

How long does a leather strap last on a watch like the Limes Endurance?

A high-quality alligator or shell cordovan strap lasts 3–5 years with moderate daily wear (5–7 days per week). A structured calf strap has comparable longevity, but depends heavily on climate, humidity, and frequency of water exposure. Patina and natural ageing are part of the beauty of a leather strap: they are indicators of authenticity, not defects. NATO or rubber straps, by contrast, require replacement every 2–3 years for functional reasons.
