Strap for Saint-Imier Date 26

The lug width of the Longines Saint Imier L2.263.5.72.0 is 20mm. This measurement corresponds to the distance between the terminal ends of the case and determines strap compatibility. To verify correct fit, measure the space between the lug pins: it must be exactly 20mm to ensure perfect seating without lateral play or forced compression.

Alligator leather represents the ideal choice for this model: the regular, fine grain maintains the refined proportions of the 26mm case, whilst the natural texture complements the rose gold finishing perfectly. An alligator strap in dark brown or black delivers longevity exceeding 5 years with proper maintenance. Alternatively, vegetable-tanned calf offers softer tactile sensation, whilst Shell Cordovan provides natural lustre and exceptional durability.

Strap replacement uses a spring bar remover tool (specific instrument for pin removal). Locate the small holes at the case ends, gently insert the remover to compress the internal spring within the pin, then extract the pin itself. Repeat on the opposite side. To install the new strap, align the holes with the pins and push until you hear the locking click. If unfamiliar with this process, consult a qualified watchmaker to prevent damage.

Yes, the Longines Saint Imier is fully compatible with quality artisanal aftermarket straps, provided the lug width measures exactly 20mm. Straps crafted from alligator, calf, Shell Cordovan or other noble materials with professional finishing integrate perfectly with the rose gold and steel case. Always verify that the strap features adequate thickness and stitching to properly support the weight of the rose gold and stainless steel case.

Longevity depends on leather type and maintenance. A quality artisanal alligator strap lasts 5-7 years with daily wear and regular cleaning. Vegetable-tanned calf ranges from 3-5 years, whilst Shell Cordovan—thanks to natural resin content—can last 7-10 years. Important: avoid prolonged moisture exposure, protect from direct heat and clean with a soft, slightly dampened cloth. Periodic water-repellent treatment significantly extends lifespan.
