Frequently asked questions
What is the lug width of the Longines Saint Imier L2.263.5.87.7?
The lug width of the Longines Saint Imier L2.263.5.87.7 is 20mm. This measurement is the distance between the two metal attachment points on the case where the strap inserts. Measuring accurately with a calliper is essential before ordering a replacement strap, as confusing it with the case diameter (26mm) is a frequent mistake leading to incompatible purchases.
Which strap is most suitable for the Longines Saint Imier L2.263.5.87.7?
For this model featuring a mother-of-pearl dial and two-tone case, the ideal strap is alligator in black, navy blue, or dark brown. Alligator amplifies the mother-of-pearl's luminosity without visual competition. Refined alternatives include vegetable-tanned calf leather in warm tones (brown, taupe) that develop an evolving patina over time, complementing the rose gold case. Avoid sporty materials like NATO, which are more appropriate for casual models.
How do I change the strap on the Longines Saint Imier L2.263.5.87.7?
Strap replacement requires removing the spring bars that secure the strap to the case. Using a dedicated spring bar tool, push one bar inward to allow the old strap to slide off. Next, insert the new strap by aligning the holes at its ends with the attachment points, then reinsert both spring bars securely. Ensure both bars are firmly seated in their slots before wearing the watch.
Can I use an aftermarket 20mm strap on this Longines?
Yes, any strap with a 20mm lug width is physically compatible with the Saint Imier L2.263.5.87.7. However, aesthetic compatibility is equally important: select quality materials (alligator, calf, artisanal rubber) that respect the model's feminine elegance. Budget or inferior-quality straps significantly compromise visual harmony.

How long does a leather strap last on a daily-worn watch?
A quality leather strap (alligator, vegetable-tanned calf) worn daily on a Saint Imier maintains structural and aesthetic integrity for 3–5 years under normal conditions. Durability depends on: frequency of wear, water exposure, perspiration, ambient humidity. Vegetable-tanned calf develops a beautiful patina over months, enhancing aesthetic value with age. Avoid prolonged contact with chlorinated water and keep the strap dry after use to extend its lifespan. When the lug attachment begins to weaken, replacement at <strong>Casati Milano</strong> is the opportune moment.
