Strap for Saint-Imier Date 26

The Longines Saint Imier L2.263.5.87.2 is fitted with straight lugs measuring 18mm. This standard applies to Longines ladies' models in the 26mm category within this collection. To verify compatibility, measure the lug width seat with digital callipers: the reading must be 18mm exactly, with no tolerance exceeding ±0.2mm, as minor deviations will prevent proper strap installation.

Polished black alligator is the primary choice, particularly on mother-of-pearl white dials, because the natural grain texture reflects light subtly without competing with the case. Vegetable-tanned calf is equally valid if you desire a patina that develops naturally over time. Avoid rubber straps for daily wear, as they would contradict the dress-watch nature of this 26mm model.

The Longines Saint Imier L2.263.5.87.2 employs standard straight 18mm lugs. Use a dedicated tool (spring-bar pusher or lug extractor) to gently press the lug pin inward until it protrudes completely. Flip the watch over and remove the old strap; align the new strap's holes with the lugs and reinsert the pin by pressing firmly until it clicks. Avoid improvised tools that could damage the case.

A quality alligator or calf strap, worn daily, has an average lifespan of 3–5 years before surface fibres begin to yield. Vegetable-tanned leather ages more elegantly than chrome-tanned leather, developing visible patina within 6 months. Wear is accelerated by constant exposure to moisture, perspiration, and UV rays. Shell cordovan requires frequent air-drying and lasts longer (5–7 years) only if the wearer's wrist remains dry and the watch is not worn in humid environments.
