Strap for Record 38.5mm Stainless Steel / White-Roman / Alligator

The lug width (ansa) of the Longines Record L2.820.4.11.2 is 20 millimetres. This measurement represents the distance between the two lugs (attachment points) of the case. Any compatible strap must have a lug width of exactly 20mm to ensure precise fitting without play or stress on the spring bars.

Alligator leather with vegetable tanning is the most elegant choice, as the natural grain of the scales contrasts beautifully with the guilloché dial geometry and develops a rich patina over time. Structured calf leather in dark tones (brown or black) offers superior everyday durability. For versatility, a grey slate or navy blue NATO fabric allows seamless transitions between formal occasions and sportier wear.

Remove the strap using a spring bar tool. Position the tool under the lateral pin (near the case), apply gentle pressure to compress the internal spring mechanism of the pin, and once the pin end is released from the case, remove it completely. Repeat for the opposite pin. To install a new strap, reinsert the pins in reverse sequence, ensuring both ends seat securely in the keeper slots of the new strap.

Yes, any strap with a 20-millimetre lug width is compatible. You may select from leather options (alligator, calf, crocodile), fabric (NATO), rubber, or steel straps. The critical requirement is verifying the lug width is exactly 20mm and the keeper thickness does not exceed 4.2mm for ergonomic fit within the original case lugs.

A high-quality leather strap made from vegetable-tanned hide and treated with water-repellent conditioners typically lasts 3–5 years with daily wear, extendable to 7–8 years with periodic maintenance (gentle cleaning and conditioning with purpose-formulated oils). Climate, humidity, perspiration exposure, and frequency of use influence longevity. Alligator and crocodile leather generally outlast standard calf leather.
