Strap for Saint-Imier Date 41

The lug width (distance between the lugs) of the Longines Saint Imier L2.766.5.59.7 is 20mm. This measurement is critical when selecting a replacement strap, as an incorrect width will result in lateral play or prevent proper fitment. The lug depth is typically 2.5–3mm, accommodating spring bars of 1.8–2mm width. Always verify this measurement using a calliper or loupe before ordering.

For the Saint Imier L2.766.5.59.7, we prioritise French alligator leather (fine grain, developing patina) or Italian vegetable-tanned calf (progressive colour evolution). The bicolour case in rose gold and stainless steel complements premium leather finishes exceptionally. For sporting or casual contexts, a heavyweight cotton NATO strap offers functional versatility. Rubber (FKM/EPDM) is ideal for aquatic environments. Avoid intense blue or bright red, which contrast the warm bicolour palette.

Strap replacement requires removal of the spring bars securing each lug to the case. Using a spring bar tool or thin needle, gently press toward the watch centre to release the retaining clip on one side, then withdraw the lug from the old strap. Insert the new strap, ensure proper alignment, and re-engage the spring bar until it clicks. Repeat on the opposite side. Never use hammers or blunt tools, which risk damaging the bicolour case.

Leather strap longevity depends on material grade, tannage method, and daily wear intensity. Premium French alligator (e.g., Hermès tannery) lasts 8–12 years with proper care (gentle cleaning, thorough drying, controlled storage). Italian vegetable-tanned calf shows similar durability whilst developing visible patina over time. NATO straps exceed this, lasting 12–15 years due to synthetic resilience against moisture degradation. Synthetic rubber (FKM/EPDM) maintains functionality for 10–12 years. Frequent replacement is advised if the strap faces sustained perspiration, humidity exposure, or prolonged UV radiation.
