Louis Erard
Excellence 34248AA66.BVA151— lug 22mm

The lug width of the Louis Erard Excellence 34248AA66.BVA151 is 22mm. This measurement refers to the internal distance between the two lugs on the watch case, and is the fundamental specification for determining strap compatibility. Ensure you measure correctly from the internal tip of one lug to the other, perpendicular to the centre of the case.

For the Louis Erard Excellence 34248AA66.BVA151, we recommend an alligator strap in black with a stainless steel deployante for maximum formal elegance, or alternatively a vegetable-tanned Tuscan calf in dark brown for a more versatile and tactile approach. Both materials respect the rigorous constructive character of the Swiss timepiece. For sporting contexts, a NATO strap in heavy cotton grey-anthracite offers an appropriate alternative.

Strap replacement is accomplished by removing the lug pins (spring bars). Use a dedicated spring bar tool to depress the hook and slide the pin out of the lug. Then insert the new strap by aligning the holes with the metal rings on the lug, and reinsert the pin until it clicks into place. Verify the pin is firmly secured before wearing the watch.

Yes, any strap with a 22mm lug width is compatible with the Louis Erard Excellence 34248AA66.BVA151. Our leather, NATO, and rubber straps in 22mm size are designed and tested for compatibility with watches in this category. We recommend selecting materials and finishes that reflect the sober and constructive character of the Swiss timepiece.

The lifespan of a leather strap depends on material quality, frequency of wear, and environmental conditions. A high-quality calf or alligator strap can last 3-5 years of moderate daily use, developing a natural patina that improves over time. Vegetable-tanned leather tends to last longer than chrome-tanned leather due to its superior density and durability. Regular maintenance and protection from moisture significantly extend the strap's life.
