Frequently asked questions

What is the exact lug width of the Limes Endurance U8777-LA2.1?

The lug width of the Limes Endurance U8777-LA2.1 is 22mm. This measurement is taken between the protruding lugs on the case shoulders. It is essential to verify this dimension before purchasing a strap: an incorrect lug width will not fit properly and will compromise the constructive integrity of the watch.

Which strap is recommended for the Limes Endurance U8777-LA2.1?

For the Limes Endurance U8777-LA2.1, we prioritise a strap in Tuscan leather with vegetable tanning, dark brown. Vegetable tanning respects the watch's constructive philosophy: it ages naturally, developing patina and irregular grain. This aesthetic evolution accompanies the satin steel case towards increasingly stratified beauty. Valid alternatives: light vegetable calf leather, textured alligator, canvas NATO for everyday versatility.

How do you change the strap on a watch with 22mm lugs?

To change the strap on a 22mm lug width watch: position the watch on a soft surface, preferably with the strap facing upward. Use a spring bar tool to gently press the small metal pin holding the strap. The pin will retract, allowing the strap to slide off. Repeat on the other side. To mount the new strap, insert one end of the lug first, guide the pin through the new strap's hole, and allow the pin to expand automatically into the opposite lug. Ensure the strap is securely positioned before wearing the watch.

Is there an aftermarket strap compatible with the Limes Endurance U8777-LA2.1?

Yes. Any strap with a 22mm lug width is physically compatible with the Limes Endurance U8777-LA2.1. Milanostraps offers a comprehensive collection of 22mm straps in various materials: vegetable-tanned leather, alligator, shell cordovan, calf, NATO, and FKM rubber. Technical compatibility is guaranteed; the challenge is selecting the material that harmonises with the Endurance's minimalist aesthetic and your personal style.

How long does a leather strap last on a watch like the Limes Endurance U8777-LA2.1?

Leather strap longevity depends on material, maintenance, and usage. A Tuscan vegetable-tanned leather strap, rotated with other straps (3-4 rotations), typically lasts 3-5 years before replacement becomes necessary. An alligator strap, thanks to the natural scale structure, can last 5-7 years. Leather ages naturally: minor creasing and colour shifts are normal and desirable. To extend lifespan, avoid prolonged exposure to direct moisture, occasionally apply leather-specific conditioner, and rotate regularly with other straps to reduce concentrated stress.
