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

For the Longines Record L2.321.0.57.2, straps in alligator leather with vegetable tanning are recommended, for aesthetic compatibility with the minimalist design philosophy. Alligator develops a natural patina that enhances the vintage character of the Record. Noble alternatives include box calf for those seeking practicality, shell cordovan for longevity and improving patina over time. For intensive daily use, FKM rubber guarantees durability and minimal maintenance. Fabric NATO straps remain compatible but alter the original aesthetic.

The strap on a Longines Record L2.321.0.57.2 is changed by removing the spring bars (elastic pins) that connect the strap to the lugs. Use a dedicated tool (spring bar tool) to gently compress the pin and slide it out from the case. Position yourself in well-lit surroundings to avoid scratches. The procedure takes 2-3 minutes for those with manual dexterity: compress the pin, insert the new strap into the lugs, release the pin until it clicks into place. If preferred, Casati Milano offers strap change service by appointment.

A quality leather strap for the Longines Record L2.321.0.57.2 typically lasts 3-5 years with daily use, depending on the leather chosen and climatic conditions. Alligator leather with vegetable tanning tends to last 4-5 years thanks to its compact natural fibre. Shell cordovan can exceed 7 years. Box calf, more subject to surface wear, lasts 3-4 years. Natural patina and micro-creasing are signs of aesthetic ageing, not structural failure. Casati Milano guarantees bespoke straps for 18 months from creation.
