Strap for Saint-Imier Date 41

The Longines Saint Imier L2.766.5.79.7 features a 20mm lug width, measured as the distance between the lugs at the case. This is a classic dimension in watchmaking, slightly less common than 22mm but ideally proportioned for the elegant design of this model and well-suited to medium to large wrists.

We recommend refined leather with vegetable tanning, particularly alligator in dark brown or aged cognac tones, which harmonise beautifully with the two-tone case in stainless steel and rose gold. Avoid glossy finishes: this classical timepiece deserves materials that develop patina over time, creating a personal bond between the wearer and the watch.

To change the strap, use a spring bar tool or consult a specialist. Position the tool on the spring bar beneath the lug from inside the case, gently press to compress the internal spring, extract the bar from its seat, and repeat on the other side. Insert the new strap by aligning the holes with the bars, then reinsert the bars until you feel a secure click. If you lack experience, consult a qualified watchmaker.

Yes, the 20mm lug width is a standard measurement, and numerous aftermarket straps are compatible. Online retailers offer a wide selection of leather, rubber and fabric options in 20mm, from artisanal suppliers to industrial manufacturers. For quality and durability assurance, choose specialised retailers who test their products on prestigious timepieces of similar calibre.

A high-quality leather strap, crafted with vegetable tanning, typically lasts 3 to 5 years with moderate daily wear. Durability depends on frequency of wear, exposure to humidity and perspiration, and care applied. A well-maintained alligator or calf leather ages elegantly, developing character and patina, often remaining wearable well beyond this period.
