Strap for Saint-Imier Date 30 Stainless Steel

The lug width of the Longines Saint Imier L2.563.4.79.0 is 15mm. This is a specific dimension that characterises many vintage Longines timepieces and requires straps constructed specifically for this width to ensure precise fitting and aesthetic balance with the 30mm case.

For the Saint Imier L2.563.4.79.0, alligator remains the ideal choice thanks to its fine grain that enhances the simplicity of the brushed stainless steel case. Alternatively, shell cordovan with vegetable tanning offers a contemporary patina narrative, whilst perforated calf represents a versatile option for summer daily wear.

To change the strap on a Longines Saint Imier, use a dedicated tool (spring bar tool) to remove the elastic pins (spring bars) from the lugs. Position the tool under the lug, gently press to disengage the spring, then extract the pin. Repeat on the other side, then insert the new strap by aligning it with the lugs and pressing until the spring clicks into the holes.

Yes, provided the aftermarket strap is constructed with 15mm compatible lugs. Milano Straps offers online a selection of artisanal straps for this specific width, as well as the possibility of customisation at the Casati Milano atelier for a bespoke experience.

A high-quality leather strap—alligator, shell cordovan, or vegetable-tanned calf—has an average lifespan of 3–5 years with daily wear. Longevity depends on frequency of wear, exposure to moisture and perspiration, and maintenance (periodic cleaning and conditioning). Milano Straps offers an 18-month warranty on bespoke straps crafted at Casati Milano.
