FAQ
What is the lug width of the Louis Erard Excellence 85237AA32.BVA36?
The lug width is 22 millimetres. This measurement is the critical parameter for strap compatibility. To verify it, use a digital calliper measuring the internal distance between the two lateral lugs of the case. Only straps specifically manufactured for the 22mm size will fit correctly onto the spring bar holes of the 85237AA32.BVA36.
What strap is recommended for the Louis Erard Excellence 85237AA32.BVA36?
For this regulator dial model, we recommend a calf leather strap with vegetable tanning in Moro head tone. The semi-opaque texture of vegetable-tanned leather contrasts elegantly with the satin-finish steel case, highlighting the regulator dial. Alternatively, a NATO strap in military tone offers a sportier aesthetic while maintaining the technical authority of the Sellita SW266-1 ND movement.
How do you change the strap on a 22mm lug width watch?
Position the watch with the lugs facing towards you. Use a spring bar tool (specific implement with a forked tip) to apply gentle inward pressure on one of the two metal lugs, compressing it. Simultaneously, extract the pin (spring bar) from the slot. Repeat the operation on the opposite lug. Insert the new pins of the strap into the slots, ensuring they click into position with an audible snap. The process takes less than one minute per side.
Is an aftermarket 22mm strap completely compatible with the Louis Erard Excellence 85237AA32.BVA36?
Yes. If the strap is specifically constructed for 22mm lug width, it will be mechanically compatible. Compatibility depends solely on lug width, not on the watch brand. Our 22mm straps have been tested with hundreds of models from different manufacturers. However, verify that the strap's spring bars are the correct length: for the slim case of the Excellence, we recommend spring bars of standard length 16–17 millimetres.
What is the average lifespan of a leather strap for the Louis Erard Excellence 85237AA32.BVA36?
A calf leather strap with vegetable tanning, worn daily, maintains structural and aesthetic integrity for 3–5 years. Lifespan depends on exposure to moisture, perspiration and ultraviolet radiation. Vegetable tanning develops a more pronounced and visible patina compared to other tanning methods. We recommend rotating the strap (wearing different straps on alternate days) to distribute wear. At end of life, the strap deteriorates gradually but remains safe until replacement, unlike synthetic materials which may crack suddenly.
