Strap for Excellence Guilloché Main II

The lug width of the Louis Erard Excellence 34237AA95.BVA103 is 22mm. This measurement represents the horizontal distance between the inner edges of the two case lugs. Accurate measurement using a digital calliper is essential to ensure absolute compatibility with the strap you intend to fit.

For the Louis Erard Excellence 34237AA95.BVA103, we recommend a leather strap crafted from noble Italian hide with vegetable tanning, which emphasises the technical and timeless character of the Swiss movement. Macerated alligator represents the most formal choice; vegetable-tanned calf with natural patina is ideal for daily wear; woven NATO in grey or black amplifies the sporty character. Your selection depends on your intended use and personal aesthetic preferences.

To change the strap, position your watch with the lugs facing towards you. Use a spring bar removal tool to gently depress the spring bar that holds the old strap in place. Once the spring bar is released, extract the strap. Insert the new strap, aligning it with the lugs, and using the same tool, snap the spring bar into the lug slots. Verify that the attachment is secure before wearing the watch.

Absolutely. The Louis Erard Excellence 34237AA95.BVA103, being equipped with standard 22mm lugs, is fully compatible with any quality strap manufactured for this lug width. Milano Straps offers a curated selection of 22mm straps in leather, fabric and rubber, all verified for fitting precision and durability. A quality aftermarket strap can entirely transform the appearance and functionality of your watch.

A leather strap crafted from noble hide with vegetable tanning typically lasts 2-4 years, depending on intensity of use, frequency of wear and maintenance. Constant exposure to moisture, perspiration and UV radiation accelerates ageing. Regular care—gentle cleaning with a damp cloth, rapid drying, storage in a cool and dry environment—significantly extends longevity. Many owners value this controlled mortality because it allows seasonal strap rotation, adapting the watch to different contexts.
