Strap for Elegant Collection Small Second 34.5 Stainless Steel / White - Roman

The lug width of the Longines Elegant L4.312.4.11.0 is 18mm. This measurement indicates the distance between the case lugs and is essential for strap compatibility. Always measure the outer distance between the lugs at the point where the strap makes contact with the case.

For the L4.312.4.11.0, we recommend straps in black or brown alligator, calf leather with vegetable tanning, or shell cordovan. These materials respect the formal aesthetic of the model and develop a natural patina over time. For casual or summer use, NATO fabric and vulcanised rubber offer practical versatility whilst maintaining correct visual proportions.

To change the strap, obtain a spring bar tool. Position it beneath the lug pin on the inner case side and push gently upwards to compress the spring, then extract the old pin. Insert the new strap's pin following the same procedure in reverse. Always verify that the strap sits equidistant from both sides of the case before wearing the watch.

Yes, any strap with an 18mm lug width is mechanically compatible. However, to preserve the aesthetic and historical value of the watch, we recommend artisanal straps of quality leather. Aftermarket straps should have felt or alcantara inner lining to protect the case from scratches, and precise stitching with durable thread.

A quality leather strap with vegetable tanning or shell cordovan typically lasts 3–5 years with daily use and regular maintenance. Longevity depends on sun exposure, humidity, and periodic cleaning with a soft cloth. Artisanal aftermarket straps generally include an 18-month warranty covering manufacturing defects, not natural leather wear.
