Frequently asked questions

What is the lug width of the Louis Erard Excellence 85237AA35.BVA35?

The lug width is 22mm, measured as the distance between the two spring bar pins that pass through the strap. All straps with 22mm lug width are interchangeable on this model.

Which strap is most suitable for the Louis Erard Excellence 85237AA35.BVA35?

Natural vegetable-tanned calf leather represents the ideal choice, as its patina evolution harmonises with the brushed steel case. Alternatively, genuine Louisiana alligator offers superior formal elegance, whilst technical NATO straps ensure practical daily wear.

How do I change the strap on this model?

Remove the strap using a spring bar tool. Position the tool underneath the spring bar pin, apply gentle pressure to compress the internal spring, extract the pin and remove the strap. Repeat with the second pin. Installation of the new strap follows the reverse procedure.

Which aftermarket straps are compatible with the 85237AA35.BVA35?

All straps with 22mm lug width are compatible. The milanostraps.it collection includes artisanal leather, genuine alligator, shell cordovan, NATO straps and vulcanised rubber. Always verify that the strap has the correct lug width.

How long does a leather strap last on this watch?

A quality leather strap treated with vegetable tanning lasts approximately 3-5 years with regular daily use. Durability depends on humidity exposure, cleaning frequency and usage intensity. A formal strap worn occasionally may last 8-10 years. Periodic maintenance such as cleaning and application of leather conditioner significantly extends longevity.
