Strap for Saint-Imier Date 26

The lug width of the Longines Saint Imier L2.263.4.87.2 is precisely 20mm. This dimension represents the distance between the two lugs on the case where the strap is secured. Verify compatibility by measuring perpendicularly between the lugs using a digital calliper. A 20mm strap will install without play or forcing, preserving both the aesthetics and functionality of the watch.

For the 26mm Saint Imier, we recommend Burmese alligator, deep burgundy shell cordovan, or vegetable-tanned calf leather. Greyish-green alligator is the natural choice for dress contexts: its pronounced grain imparts character without overwhelming the formal elegance. Cordovan represents the pinnacle of luxury tanning, evolving in patina from bright mahogany to deep brown over time. Your selection should harmonise with the satin case and silver dial.

Remove the watch and place it on a soft surface. Using a strap changing tool or flat non-abrasive instrument, gently push the spring bar towards the case centre to release tension. Extract the spring bar completely and remove the old strap. Align the new strap's lugs and insert the spring bar, ensuring the hooks engage fully. Verify the strap is properly centred before wearing the watch.

Absolutely. Any strap with a 20mm lug width is compatible with the Saint Imier L2.263.4.87.2. Online you will find 20mm straps in alligator, cordovan, calf, NATO and rubber, customisable in colour, length and stitching thread. Always verify that the strap is constructed specifically for the 20mm dimension to ensure precise installation without damaging the case lugs.

A quality leather strap (alligator, calf, cordovan) typically lasts 3–5 years with daily use, depending on climate, care and intensity of wear. Cordovan is the most durable leather, with minimal wear and patina that improves aesthetically. Vegetable-tanned leather resists UV rays and humidity better. Protect the strap from stagnant water, perfumes and aggressive detergents. Rotating between two straps significantly extends the life of both. Luxury brands offer 18–24 month warranty on artisanal products.
