Strap for Saint-Imier Date 38.5

The lug width of the Longines Saint Imier L2.763.5.52.7 is precisely 20 mm. This measurement corresponds to the internal distance between the two lugs of the case and represents the specific standard for this model. When selecting a compatible strap, always verify with the seller that the strap is specified as compatible with 20 mm lugs to ensure a perfect fit.

For the Saint Imier L2.763.5.52.7, the ideal material is premium alligator leather, which naturally complements the two-tone case's minimalist aesthetic. Quality alligator features fine and uniform grain, soft yet structured leather, and develops an elegant patina over time. Alternatively, Taurillon calf leather with vegetable tanning offers slightly more texture and a fascinating natural ageing process.

Strap replacement is a straightforward operation requiring no specialised tools. Position the watch case upward and locate the pin connecting the spring bar to the case. Using a fine-pointed tool (or a dedicated spring bar tool), apply gentle upward pressure on the pin to compress the internal spring, then remove the old strap. Insert the new strap by aligning the pin with the slots and allow the spring to reposition naturally. To avoid the risk of scratches, the Casati Milano atelier offers professional strap-change services by appointment, with guaranteed manual expertise.

Yes, the Longines Saint Imier L2.763.5.52.7 is fully compatible with quality aftermarket straps. The only technical constraint is the 20 mm lug width, which must be respected precisely to ensure secure and comfortable fitting. MilanoStraps provides an extensive selection of 20mm compatible straps, customisable in length, leather choice, initials and thread colour, with warranty and rapid dispatch.

The lifespan of a leather strap depends on material quality, frequency of wear and exposure to atmospheric agents. Premium alligator or Taurillon calf with vegetable tanning typically lasts 3–5 years of daily use, with an increasingly appealing patina over time. Shell cordovan, due to its structural density, can exceed 5–7 years. Factors such as humidity, perspiration and thermal variations influence ageing. MilanoStraps straps are guaranteed for 18 months and crafted from hides specifically selected for durability and aesthetic development over the long term.
