Strap for BelleArti 24.6 Stainless Steel

The Longines Heritage L2.501.4.73.6 features a lug width of 20 millimetres. This measurement is critical for selecting a compatible strap: place a ruler between the two spring bars to verify that your chosen strap is exactly 20 mm wide, preventing mechanical stress on the case lugs.

To honour the vintage character of the L2.501.4.73.6, an alligator strap in dark brown or vegetable-tanned calf leather represents the most authentic choice. If you prefer versatility, polished black calf or a quality vulcanised rubber strap offer durability and everyday practicality. Your selection should reflect your personal style and the activities for which you wear the watch.

To change the strap, gently extract the spring bars using a dedicated tool (spring bar tool) or seek professional assistance. Position the tool in the small lateral recess of the bar and push inward until the bar releases from the case. Repeat on the opposite side, then insert the spring bars of your new strap and verify they are properly seated. If uncertain, consult a professional watchmaker.

Yes, the Longines Heritage L2.501.4.73.6 with its 20 mm lug width is compatible with a wide range of quality aftermarket straps. On milanostraps.it you will find straps in alligator, calf, NATO, shell cordovan, and rubber, all customisable in dimensions, initials, and stitching thread. Compatibility is guaranteed by the standard 20 mm lug width.

Lifespan depends on material and frequency of use. A quality alligator strap lasts 4–6 years with regular wear, developing a captivating patina over time. Standard calf leather typically lasts 2–4 years. Vegetable-tanned leather tends to last longer and improves with age. To extend strap life, avoid prolonged direct sunlight exposure and periodically clean the strap with a microfibre cloth.
