Strap for Excellence Chrono Monopoussoir Stainless Steel / Silver

The lug width of the Louis Erard Excellence 74239AA01.BVA31 is 22mm. This dimension is engineered to maintain optimal proportions on the 43mm case, ensuring aesthetic and functional balance. To verify your watch's lug width, use a digital calliper measuring the distance between the internal case lugs.

For the Louis Erard Excellence 74239AA01.BVA31, we recommend a strap in vegetable-tanned Tuscan leather (Testa di Moro shade) that emphasises the independent watchmaking identity, or black calf leather for formal contexts. If versatility is preferred, a canvas NATO or antracite rubber offer quick swaps whilst maintaining the monopoussoir chronograph's functional simplicity.

To change the strap, use a spring bar tool or visit a qualified watchmaker. Position yourself at the internal lug, press downward to release the spiral spring, then remove the lug. Repeat on the other side. Insert the new strap by aligning the lug with the case lugs, then press until it clicks into place. Verify the spring is correctly seated.

Yes, any strap with a 22mm lug width is compatible. Milano Straps offers a complete selection of artisanal straps in leather, NATO and rubber, ready to ship and customisable according to your colour and material preferences. Always verify that the lug width is declared as 22mm by the seller.

A quality leather strap, such as vegetable-tanned Tuscan or calf leather, lasts 3-5 years with moderate daily wear. Longevity depends on exposure to moisture, perspiration and mechanical stress. Vegetable-tanned straps develop a characteristic patina, acquiring aesthetic authenticity over time. Regular maintenance (drying, conditioning) extends service life significantly.
