Strap for Excellence La Semaine Blanche Louis Erard x Alain Silberstein Titanium / White

The lug width of this model is 23mm, a specific dimension requiring dedicated straps. This width, wider than the standard 20mm, allows for thicker materials to be worked, creating a more robust lug keeper and optimal visual proportion between case and strap. To verify compatibility, measure from inner edge to inner edge of the lug width using a digital calliper.

For this titanium timepiece, a dark alligator strap with fine grain represents the most elegant choice, creating an ideal visual contrast with the satin-brushed case. Equally recommended are a vegetable-tanned calfskin in natural tone, a silk-blend NATO in matching tone, or a satin-black leather strap with titanium deployante for complete material synergy.

Use a quality spring bar tool. Position the watch on a soft surface, insert the tool's tip into the lug slot, push upward to release the spring bar, and remove the old strap. Align the new strap's hole with the spring bar, press downward until you hear a click of engagement. Verify the strap is securely fastened.

Yes, provided the strap is specifically crafted for 23mm lug width. Milano Straps' artisanal straps are built to exact millimetre specifications for this width, ensuring a perfect fit without gaps between case and lug. Always verify the technical specifications before purchase to avoid incompatibility.

Strap longevity depends on daily wear, climate, and tanning method. A vegetable-tanned calfskin, used regularly, maintains structural and aesthetic integrity for 3-5 years. Alligator, particularly durable, exceeds 7-10 years. To extend lifespan, apply conditioning balms every six months and avoid prolonged exposure to humidity and direct sunlight.
