FAQ

What is the lug width of the Louis Erard Excellence 75357TT25.BTT82?

The lug width is 23mm. This measurement should be verified by positioning a digital calliper between the two lugs of the case, on the external shoulder width. Do not confuse it with approximate dimensions: 23mm is specific and not interchangeable with 22mm or 24mm.

Which strap pairs best with the Louis Erard Excellence 75357TT25.BTT82?

It depends on intended use. For formal context, we recommend black or dark brown alligator with vegetable tanning. For balanced sportiness, shell cordovan in mahogany tones or medium brown calf. For daily versatility, a grey NATO or antique grey vegetable-tanned leather. Black FKM rubber is ideal for intensive sport use.

How do I change the strap on a watch with a 23mm lug width?

Remove the watch and place it on a soft cloth. Using a spring bar tool, gently press downward on the lug spring, lifting the elastic pin. Once removed, insert the new strap by aligning the holes to the lugs, then reinsert the pin with the spring. Verify that the strap is secure before wearing.

Can I use a compatible 23mm aftermarket strap on the Louis Erard Excellence?

Yes, provided the lug width is precisely 23mm. Milano Straps offers curated selections for this specific measurement, guaranteeing perfect architectural compatibility. Always verify the product dimensions before purchase to avoid discrepancies.

How long does a leather strap last on a watch like the Louis Erard Excellence 75357TT25.BTT82?

A quality leather strap (alligator, shell cordovan, vegetable-tanned calf) typically lasts 3-5 years with daily use. Longevity depends on frequency of use, moisture exposure, and care. Vegetable tanning tends to develop natural patina, visually extending the strap's aesthetic life.
