Strap for Saint-Imier Date 26

The lug width (misura ansa) of the Longines Saint Imier L2.263.9.87.3 is 20mm. This measurement represents the internal distance between the two attachment pins of the case. It is crucial for selecting a compatible strap: a 20mm strap will fit perfectly between the lugs, ensuring correct proportions on the 26mm case. To verify accurately, use a digital calliper, inserting it gently between the pins without forcing.

Alligator leather with vegetable tanning is the ideal choice for this timepiece. The regular texture of the grain and natural colour of alligator integrate magnificently with rose gold, creating sophisticated visual harmony. A deep cognac alligator emphasises the warmth of the case, whilst black alligator offers timeless formal elegance by contrast. Shell cordovan represents an excellent alternative, developing deep patina over time that parallels the case. Fine-grain calf leather in havana or medium brown shades provides versatility whilst maintaining sobriety.

Strap replacement is accomplished by removing the case pins using a spring bar tool. Position the tool on the flat section of the pin, applying inward pressure to release the internal spring. The pin will snap out, allowing complete removal. To install the new 20mm strap, align the lug holes with the pins and reinsert the pin from the outside, ensuring the spring clicks correctly. Avoid forcing to prevent damage to the rose gold lugs.

An artisanal strap in full-grain leather, specifically constructed for 20mm lugs, represents the finest compromise between quality, durability and aesthetics. Bespoke straps from Milanostraps compatible with this measurement are crafted from vegetable-tanned leather that ages naturally, developing patina reflecting the rose gold case. Choose finishes including hand-stitching and a rose gold deployante buckle to maintain stylistic coherence. Personalise with initials or thread colour for individual character.

A quality strap in vegetable-tanned leather resists approximately 18-24 months with daily wear, extending to 3-4 years with intermittent use. Longevity depends on exposure to moisture, perspiration and mechanical wear. Alligator and shell cordovan are particularly resistant owing to fibre density, prolonging strap life. Regular applications of natural wax conditioner extend durability. The 18-month artisanal guarantee covers construction defects. Wear is a natural and desirable evolution: patina development is part of the characteristic ageing of vegetable-tanned leather.
