Frequently asked questions

What is the lug width of the Limes Endurance U8797B-LC2.3?

The lug width of the Limes Endurance U8797B-LC2.3 is precisely 20.00 mm. This measurement is the fundamental parameter for selecting compatible straps. It should be measured with precision using a digital calliper in the space between the two lugs of the case.

Which strap is most suitable for the Limes Endurance U8797B-LC2.3?

For the Endurance, we recommend caramel alligator straps for sartorial elegance, vegetable-tanned calf leather for daily wear with natural ageing, or NATO and FKM rubber for sporty versatility. The choice depends on primary use: formal, casual, or technical-dynamic.

How do I change the strap on a Limes Endurance U8797B-LC2.3?

Position the watch on a soft surface to prevent scratching. Locate the barrel connectors (small metal cylinders at the lug ends). Using a spring bar tool, gently press downward on one of the internal spring mechanisms, extracting the metal bar. Repeat on the other side. Align the new strap's barrel connectors and reinsert the spring bar using the tool.

Can I use third-party aftermarket straps on the Limes Endurance U8797B-LC2.3?

Yes, provided the strap is dimensioned for a 20 mm lug width. Any artisan or industrial strap with the correct width is compatible. However, ensure that the lugs are sufficiently thin to avoid geometric conflicts with the case lugs.

How long does a leather strap last on a Limes Endurance U8797B-LC2.3?

A quality artisan leather strap with vegetable tanning and natural tannins lasts 3-5 years with moderate daily wear. Longevity depends on exposure to moisture, direct sunlight, and wearing frequency. Periodic maintenance with specialised balms significantly extends the strap's useful life.
