Multifort M038.662.37.050.00— lug 23mm

The lug width is 23mm. This dimension is specific to the Multifort and is the value you must verify when selecting a compatible strap. To measure it correctly, place a ruler across the inner shoulders of the lugs, precisely where the strap anchors to the case.

The choice depends on your intended use. For a formal aesthetic, we recommend alligator or shell cordovan mounted on a deployant clasp crafted from the same material. For a sports-vintage style, a grayish or dark blue nylon NATO emphasises the instrument-grade nature of the chronograph. In humid environments or for intensive wear, an FKM rubber strap delivers absolute practicality without compromising durability.

Obtain a spring bar tool (a small rod with levers at both ends). Position the watch with the lug facing upward, insert the tool's tip into the small lateral hole beneath the lug, lift gently to release the internal spring tension, then withdraw the metal rod (spring bar). Repeat on the opposite side. Reverse the procedure with your new strap, ensuring both ends of the spring bar are correctly seated in the lug holes.

Yes, provided the strap is genuinely manufactured for a 23mm lug width. Aftermarket straps of artisanal quality, such as those offered by Milano Straps, often feature superior construction compared to original straps, with carefully selected leathers and reinforced stitching. Always verify the declared lug width before purchase to prevent misalignment.

A quality artisanal leather strap, subjected to moderate use (5–6 days weekly), typically lasts 3–5 years before requiring replacement. Longevity varies with material: vegetable-tanned leather tends to patinate rather than wear; shell cordovan resists deterioration for 7+ years if protected from excessive moisture. Rotating between multiple straps significantly extends the life of each one.
