Strap for Saint-Imier Date 38.5

The lug width of the Longines Saint Imier L2.763.8.52.3 is 20 millimetres. This measurement is taken between the two internal lugs of the case and determines the maximum thickness of the watch strap lug width. A strap narrower than 20mm would be unstable; one wider would not fit. To verify the measurement, simply remove the original strap and position a calliper between the two lugs.

For the Saint Imier in rose gold, we recommend a strap in alligator (cognac brown, black, or smoke grey) or vegetable-tanned calf leather. Alligator, with its irregular grain texture, enhances the luminosity of gold without competing with it. Natural calf transmits sobriety and acquires patina over time, creating an aesthetic synergy with the aged metal. For those seeking versatility, shell cordovan amplifies the chromatic richness of rose gold. A dark rubber strap with texture is suitable for informal summer wear.

To change the strap, remove the watch from its current strap. Position the lug on a soft support (folded cotton cloth). Using a spring bar tool – available in basic watch tool kits – gently push the pin from the opposite side of the watch, sliding it out. Once both pins are removed, the old strap falls away. Insert the new strap by aligning the lugs with the case, reinsert the pins, and verify that the strap is secured firmly. If you are not experienced, consult a watchmaker or the Casati Milano atelier for professional service.

No. Compatibility depends on lug width (20mm) and attachment type (straight pin), not brand. Quality aftermarket straps – such as those offered by MilanoStraps.it – are fully compatible with the Saint Imier, provided they respect the 20mm measurement. In fact, a quality artisanal strap often imparts a new aesthetic identity to your watch, personalising its expression. What matters is that the strap lug width is free from sharp edges that could scratch the case lugs during insertion.

The lifespan of a leather strap depends on intensity of use, climate, and care. A quality alligator or calf strap, subjected to moderate daily wear (8–10 hours per day) and stored in dry conditions, can last 3–5 years before showing significant signs of wear. In very humid climates or with constant exposure to perspiration and heat, lifespan may be reduced. Vegetable tanning slows the natural degradation of leather. A premium strap, such as those from MilanoStraps.it, includes an 18-month warranty. To extend lifespan, alternate straps – wear one every other day – and clean periodically with a soft, dry cloth.
