Strap for Avantgarde Date – Re-launch Edition Stainless Steel / Blue / Alligator

The lug width of the Lebois & Co Avantgarde 112.422 is 20mm. This measurement is taken using a digital calliper positioned between the central pins of the case (the metal protrusions where the strap attaches). Precise measurement is essential when ordering a compatible aftermarket strap.

The optimal strap depends on intended use. For formal occasions, we recommend deep brown or black alligator, or calf leather with a semi-gloss finish. For daily wear, vegetable-tanned calf offers versatility and develops authentic patina over time. For casual-sport contexts, a cotton NATO in khaki or a grey-anthracite rubber strap provides practicality whilst maintaining aesthetic coherence with the case.

Strap replacement requires minimal tools: a spring bar removal tool and a stable work surface. Locate the horizontal metal pins securing the strap to the case lugs. Using the tool, gently compress the pin inward whilst pulling the strap laterally to disengage it. Align the new strap's hole with the pin and release to secure. If unfamiliar with the procedure, Atelier Casati Milano offers personalised fitting services by appointment.

Yes, though standard market availability is limited. The 20mm lug width is not a common standard like 18mm or 22mm. Milanostraps.it curates a selection of 20mm-compatible straps in alligator, calf, NATO, and rubber, constructed to artisanal specifications. Atelier Casati Milano further personalises each commission according to your colour and finish preferences.

Longevity depends on material, frequency of wear, and maintenance. An alligator or vegetable-tanned calf strap, worn daily, maintains acceptable functionality and appearance for 3–5 years. With proper care (drying after moisture exposure, gentle cleaning, semi-annual conditioning with neutral wax), longevity extends beyond 5 years. Cotton NATO straps last 2–3 years. Natural rubber, if of quality, endures 3–4 years before hardening occurs.
