Strap for Conquest Automatic 39 Ceramic

The Longines Conquest L3.655.4.86.0 features a 19mm lug width. This dimension is specific to this 39mm model and is not compatible with other watches requiring different lug widths. To verify correctly, measure the distance between the attachment holes of the current strap, from inner shoulder to inner shoulder.

For this model we recommend alligator in dark shades for those seeking elegant sportiness, burgundy or coffee-toned leather for formal balance, or grey rubber if the watch encounters marine environments. Do not compromise on sizing: 19mm is precise, not negotiable. All our 19mm straps are available online at milanostraps.it, customisable in stitching thread and initials.

The Longines Conquest L3.655.4.86.0 uses fixed straight lugs. Remove the current strap using a dedicated tool (spring bar tool) inserted into the lateral hole of the lug to compress the internal spring. Once freed, extract the strap from the hole. Insert the new strap by aligning the lug to the hole and press until the spring clicks. Contact Casati Milano if you prefer professional service with warranty.

No. The 19mm lug width is specific to the Conquest L3.655.4.86.0 and models in the same family with 39mm case diameter. Longines watches with larger cases (41mm) or smaller ones require different lug widths (20mm, 21mm, etc.). Always verify the exact lug width of your specific watch before purchasing a strap.

A leather strap (alligator, calf, shell cordovan) typically lasts 3-5 years with daily wear, depending on perspiration, UV exposure and maintenance. Vegetable-tanned leather ages more visibly, developing a patina that many collectors prefer. Casati Milano offers an 18-month warranty on all custom straps and provides consultation on maintenance and replacement.
