FAQ
What is the exact lug width of the Limes Endurance U4515-LC3.1?
The lug width of the Limes Endurance U4515-LC3.1 is 20mm. This is a specific measurement requiring dedicated straps that are not interchangeable with common 18mm or 22mm sizes. Measurement should be taken between the inner shoulders of your spring bars using a digital calliper for absolute precision.
Which strap would you recommend for the Limes Endurance U4515-LC3.1?
For this Swiss sports chronograph, we recommend Italian shell cordovan from vegetable tanning first, which develops a satin patina that perfectly dialogues with the satin-finished steel case. African alligator represents the luxury option, whilst Tuscan calf in cognac or charcoal black conveys sober construction with rapid patina development.
How do I change the strap on my Limes Endurance?
To change the strap, locate your spring bars (the straight pins connecting the strap to the case). Use a dedicated tool (spring bar tool) or a small screwdriver to gently compress the pin inward and slide it from its seats. Once freed, insert the new strap ensuring the spring bars click firmly into their seats without lateral play.
Are aftermarket 20mm straps compatible with the Limes Endurance U4515-LC3.1?
Yes, any strap with straight 20mm lugs is compatible, provided your spring bars are in correct working condition. Milano Straps offers a complete selection of artisanal 20mm straps in leather, NATO, and rubber, customisable for lug hole diameter and finishes according to your aesthetic preference.
What is the lifespan of a natural leather strap on a sports chronograph like the Limes Endurance?
A vegetable-tanned leather strap, if subjected to regular use and proper maintenance, maintains structural integrity for 3 to 5 years. The aesthetic patina improves after the first 6-12 months. Italian shell cordovan ages more slowly but develops superior chromatic depth. Alligator, if protected from prolonged direct sun exposure, easily exceeds 7-10 years of daily wear.
