Frequently asked questions
What is the lug width of the Longines Saint Imier L2.563.5.59.3?
The lug width of the Longines Saint Imier L2.563.5.59.3 is 15mm. This measurement represents the outer distance between the two lugs (spring bar attachments) that connect the strap to the case. To verify it, position a ruler on the case lugs at the level of the pin holes: the distance between the pins will invariably be 15mm.
Which strap material do you recommend for this Longines?
For the Saint Imier L2.563.5.59.3, we recommend straps in Nile alligator with vegetable tanning, offering a regular grain and natural patina development over time. Vegetable-tanned calf leather represents a more informal and versatile alternative. For those seeking extraordinary durability, shell cordovan guarantees resistance to abrasion for decades. Rubber or NATO straps are ideal for sporting or casual contexts.
How do you change the strap on this Longines?
Strap replacement requires a specific tool: the spring bar tool. Locate the spring bars (horizontal metal springs) at the case ends; using the tool, gently compress the spring toward the case centre to free the pin. Once the pin is removed, you can slide off the old strap and insert the new one. Ensure the pin is fully inserted and the spring snaps securely into the locked position.
Is the original strap compatible with aftermarket straps?
Yes. Since the standard lug width is 15mm, any artisanal strap manufactured for this measurement will be compatible with the L2.563.5.59.3. On milanostraps.it you'll find a wide selection of custom 15mm leather straps, customisable in length, colour and stitching thread, guaranteed for 18 months.
How long does a leather strap last on this watch?
Durability depends on the tanning method and material. A quality artisanal vegetable-tanned calf strap typically lasts 3–5 years with daily wear, developing a fascinating patina over time. Nile alligator, thanks to its denser fibre structure, can last 5–8 years. Shell cordovan, due to its extraordinary resistance, can exceed 10–15 years. Natural wear is part of the charm: leather softens and develops character. Regular maintenance (gentle cleaning, occasional conditioning) significantly extends lifespan.
