Strap for Record 40mm Stainless Steel / Blue-Arabic / Alligator

The lug width of the Longines Record L2.821.4.96.4 is precisely 20 millimetres. This measurement refers to the distance between the lugs (spring bars) that attach the strap to the case. Accurate measurement is essential to ensure compatibility and secure mechanical attachment.

For the Longines Record L2.821.4.96.4, we recommend straps in alligator leather with regular texture and fine grain, in neutral tones such as black, dark brown or slate grey. Alligator emphasises the instrumental elegance of the collection and the natural robustness of the leather guarantees durability. Alternatively, aniline calf or shell cordovan add tactile sophistication and patina that develops over time.

To change the strap, first remove the spring bars (lugs): use a flat lever tool to carefully disengage the pins from the case lugs. Once the pins are free, slide the old strap out of the lugs. Insert the new 20mm strap into the lugs, align the holes and reinsert the pins using a light hammer and punch. Verify that the pins are fully positioned in the lugs.

Yes, you can use aftermarket straps as long as they are constructed for a 20mm lug width. High-quality artisanal straps made from premium leathers such as alligator, calf or shell cordovan not only guarantee mechanical compatibility but significantly enhance the aesthetics and daily comfort of the timepiece. Always ensure that the strap respects the exact 20mm measurement.

The lifespan of a leather strap depends on the material, tanning method and daily use. A high-quality alligator strap with vegetable tanning can last 5-8 years with daily wear. Shell cordovan, being more durable, can exceed 10 years. The patina that develops over time is an aesthetic asset, not a defect. Factors such as sun exposure, humidity and perspiration accelerate ageing; regular care and rotation with other straps significantly extends useful life.
