Strap for Record 30mm Stainless Steel / Diamond / Black-Diamond / Bracelet

The lug width of the Longines Record L2.321.0.57.6 is 20mm. This measurement refers to the distance between the pin holes on the case. To verify, remove the pins from the inside of the lugs and measure with a calliper: you will obtain exactly 20mm. This dimension is standard on classic European watches and guarantees broad compatibility with artisanal and aftermarket straps.

For the Record L2.321.0.57.6, an alligator strap in grey or brown with medium grain is the ideal choice, as it emphasises the watch's minimalist heritage. Shell cordovan represents a luxury alternative with natural patina development over time. For daily use, vegetable-tanned calf or NATO straps offer durability. Avoid saturated colours: the Record requires sophisticated tones that communicate through subtle nuances.

To change the strap, remove the case pins from the inside of the lugs using a dedicated pin remover (available online at modest cost). Insert the pin remover into the hole and push gently until the pin exits. Remove the old strap, align the new strap's holes with the pins, and reinsert the pins until locked. A five-minute operation requiring no technical expertise. If preferred, our specialists at Casati Milano perform the service free of charge on straps purchased from us.

Yes, the 20mm strap is compatible with any watch featuring a lug width of the same dimension. Many classic Swiss and European watches use 20mm, including Omega, Jaeger-LeCoultre, Zenith and other vintage models. However, always verify the measurement with a calliper before purchase to avoid misalignments. Artisanal straps from Casati Milano are crafted with millimetre tolerances for precise fitment.

Longevity depends on material and usage. Premium alligator with vegetable tanning lasts 5-7 years with daily wear, developing pleasant patina over time. Shell cordovan resists 7-10 years, improving aesthetically with age. Pressed calf lasts 3-5 years. The most frequent failure point occurs at the bend zones near the lugs. Casati Milano straps include an 18-month warranty against manufacturing defects and naturally occurring ageing issues.
