Strap for Saint-Imier Date 26

The lug width of the Longines Saint Imier L2.263.0.87.2 is 20 millimetres. This measurement represents the internal distance between the two lugs where the strap attaches to the case. To verify it, use a digital calliper positioned perpendicularly inside the lug. A strap with the correct lug width ensures visual and functional stability, avoiding lateral gaps or failed attachments to the lugs.

Strap changing requires specific tools: a spring bar tool and a stable work surface. Position the watch case-up, locate the two lateral lugs and use the lever to compress the small spring inside each lug. Maintain pressure while gently sliding the old strap away. Repeat the operation with the new strap, ensuring the springs engage correctly in the lugs. If you are inexperienced, consult a professional watchmaker to avoid damage to the case.

The lifespan of a leather strap depends on material, frequency of use and environmental conditions. Vegetable-tanned alligator will typically last 5-7 years with regular daily use. Anilina calf, being softer, may last 3-5 years before showing visible signs of wear. FKM rubber and textile NATO straps are more durable, lasting up to 8-10 years. Expose the strap to moderate humidity, avoid prolonged water immersion and keep it clean with soft cloths. Casati Milano offers 18-month warranty on bespoke straps, with scheduled renewal options.
