Frequently asked questions

What is the lug width of the Louis Erard Excellence 34248AA05.BVA134?

The lug width of the Louis Erard Excellence 34248AA05.BVA134 is 22mm. This measurement represents the distance between the two case lugs where the strap attaches. It is a standard width with broad availability in the artisanal and aftermarket strap market, allowing you to select from numerous options in materials, colours, and styles.

Which strap do you recommend for the Louis Erard Excellence 34248AA05.BVA134?

For the Louis Erard Excellence 34248AA05.BVA134, we recommend an alligator strap in vegetable-tanned leather in dark brown, which accentuates the dial's geometry and harmonises naturally with the brushed steel case. For a more casual aesthetic, aged brown calf leather develops authentic patina over time. For sporting occasions, a heavyweight cotton NATO in grey anthracite maintains formal elegance whilst reducing visual weight.

How do I change the strap on the Louis Erard Excellence 34248AA05.BVA134?

Strap replacement requires two essential tools: a spring bar tool and a small pair of tweezers. Position the watch on a stable surface, insert the small hook of the tool into one of the lateral holes of the lower lug attachment, exert light outward pressure to release the spring, and extract the bar. Repeat on the opposite side. Insert the new strap by reversing the procedure, ensuring the bars are fully seated in the holes.

Can I use third-party compatible straps with the Louis Erard Excellence 34248AA05.BVA134?

Certainly. The Louis Erard Excellence 34248AA05.BVA134 utilises a standard 22mm lug width, compatible with any high-quality artisanal or aftermarket strap designed for this width. Verify that the strap features attachments (or bars) of matching width to guarantee perfect fit without play or excessive tension.

What is the expected lifespan of a leather strap for the Louis Erard Excellence 34248AA05.BVA134?

The lifespan of a leather strap depends on frequency of wear, climatic conditions, and tanning quality. A high-quality vegetable-tanned leather strap, worn regularly, develops authentic patina for 3–5 years before requiring replacement. Exposure to humidity, perspiration, and sunlight accelerates wear. Periodic cleaning with a damp cloth and occasional treatment with natural balm significantly extends the strap's serviceable life.
