Strap for Presence 25.5 Automatic Stainless Steel / White

The lug width of the Longines Presence L4.321.4.18.2 is precisely 13mm. This measurement is essential to ensure compatibility with aftermarket straps and to maintain the harmonious proportions between the case and the strap. Measuring correctly means positioning a ruler between the two internal shoulders of the strap attachment points on the case. An accurate 13mm measurement ensures there are no visible misalignments and that the overall ergonomics of the timepiece are optimal.

For the Longines Presence L4.321.4.18.2, alligator represents the finest choice due to its durability and natural geometric grain that dialogues perfectly with the case's simplicity. Vegetable-tanned alligator offers a patina that evolves over time, developing remarkable depth of colour. Calf leather, available in smooth or fine grain finishes, is a versatile and comfortable alternative for daily wear. For more informal contexts, cotton NATO straps allow seasonal rotation without stylistic compromise.

Changing the strap on the Longines Presence L4.321.4.18.2 is accomplished via spring bars, two small metal pins that secure the strap to the case lugs. To replace the strap, you need a spring bar tool to compress the pins and remove them from their seats. Once removed, the old strap releases easily. To install the new 13mm strap, align the ends with the lugs and reinsert the spring bars into their seats until you hear or feel a click. The operation requires no special expertise and can be completed in minutes.

The Longines Presence L4.321.4.18.2 is compatible with all artisanal straps with a 13mm lug width. Milano Straps offers a specialised range of straps in alligator, calf, shell cordovan and vegetable-tanned leather, all available with personalisation in precise sizes, initials and choice of stitching thread. Compatibility is guaranteed by the precision of the lug width: any 13mm strap will fit correctly into the case lugs.

The lifespan of a leather strap depends on the material and conditions of use. A quality alligator or shell cordovan strap can last between 7 and 10 years with regular maintenance and seasonal rotation. Calf leather, being particularly versatile, has an average lifespan of 5-7 years. Factors such as sun exposure, humidity and frequency of wear influence this estimate. Milano Straps guarantees 18 months on the strap, but the actual durability will be significantly longer if the strap is stored under optimal conditions and periodically rotated with other options.
