Frequently asked questions

What is the lug width of the Louis Erard Excellence 86236NN22.BDCN51?

The lug width of the Louis Erard Excellence 86236NN22.BDCN51 is 22mm, measured inside-to-inside between the two attachment pins. This measurement is indicated by the numerical suffix in the official reference. To verify it yourself, use a digital calliper positioned between the lugs without applying excessive pressure.

What is the best strap choice for the Excellence 86236NN22.BDCN51?

The ideal strap depends on intended use and context. For formal elegance, we recommend grey-stone alligator or vegetable-tanned calf leather in cognac tone. For versatile sportiness, a navy NATO or black matte rubber strap. The choice should respect the minimalist geometry of the regulator and its austere design philosophy.

How do I change the strap on this watch?

The Louis Erard Excellence 86236NN22.BDCN51 features integrated lugs with removable pins. To replace the strap: unscrew the crown, position the watch face-down on a soft surface, use a spring bar tool to press the inner pin toward the centre and slide it out. Repeat on the opposite side, then install the new strap by reversing the procedure.

Which aftermarket straps are compatible with reference 86236NN22.BDCN51?

Any strap with a 22mm lug width is compatible with this watch. Milano Straps offers a comprehensive 22mm collection in alligator, Tuscan calf, shell cordovan, NATO and rubber. Always verify that the strap is fitted with standard 22mm pins and check thickness dimensions relative to your original pins.

How long does a leather strap last on this watch?

A quality leather strap (alligator, calf, shell cordovan) typically lasts 3-5 years with daily wear, depending on care and sun exposure. Vegetable-tanned leather develops a natural patina that improves over time. Critical factors include: avoiding stagnant water, protecting from direct heat sources, periodic cleaning with a damp cloth. Replacement is straightforward and requires no watchmaker intervention.
