Strap for Saint-Imier Date 30 Two Tone

The lug width of the Longines Saint-Imier L2.563.5.52.7 is 15 mm. This width is specific to the 30 mm women's model and is compatible exclusively with straps designed for this dimension. Before purchasing an aftermarket strap, always verify the lug width by measuring the distance between the case lugs at the narrowest point.

For the Saint-Imier L2.563.5.52.7 30 mm model, full alligator straps with a deployant clasp represent the most sophisticated and balanced solution. Alternatively, shell cordovan (vegetable-tanned cordovan leather) offers a rich texture and develops a patina over time. For sporty contexts, a nautical NATO strap in linen-cotton maintains the elegant restraint of the model whilst adding versatility.

Changing the strap on the Saint-Imier requires a specific tool (spring bar tool). Position yourself facing the case and identify the horizontal pins beneath it. Gently insert the tool to compress the spring, then carefully extract the old pin to avoid scratching the case. Insert the new strap whilst keeping the pin compressed, then release the spring. If you lack experience, consult a specialist watchmaker or an atelier such as Casati Milano.

Compatible aftermarket straps must have a 15 mm lug width. milanostraps.it offers a dedicated collection of artisanal straps for this specific width, customisable in leather, colour and details. All models in the 15 mm catalogue are certified for the Saint-Imier and similar watches. Avoid straps with standard widths (16 mm, 14 mm) to prevent forced fitting.

A quality leather strap (alligator with vegetable tanning or shell cordovan) lasts 5–7 years under normal wear conditions with regular maintenance. Longevity depends on frequency of wear, humidity exposure and the type of tanning. Artisanal straps from Casati Milano come with an 18-month warranty and can undergo regeneration treatments to extend their lifespan. Replacement is recommended when the strap loses elasticity or shows evident signs of wear at the buckle.
