Strap for PrimaLuna Automatic 26.5

The lug width of the Longines PrimaLuna L8.111.7.16.6 is 6mm. This is the distance between the two strap attachment points and is a critical specification for selecting the correct strap. Do not confuse this with the case diameter, which is 26.5mm: the lugs are intentionally narrow to maintain the elegant, micro proportions of this women's model.

High-quality alligator leather is the natural choice for the yellow gold PrimaLuna. A cognac brown or dark brown tone creates a perfect aesthetic dialogue with the precious metal. Alternatively, shell cordovan is an even more refined option, thanks to its colour depth and ability to develop a patina over time that mirrors that of the case. Full-grain vegetable-tanned calf is suitable for those preferring more lively and characterful textures.

Strap replacement requires a dedicated tool: a spring bar tool. Insert the thin end of the tool into the access hole at the side of the lug (at 12 o'clock or 6 o'clock), compress the internal pin and pull the strap outward. Repeat on the other side. When positioning the new strap, ensure the pin clicks securely into place. If unfamiliar with the procedure, entrust the task to a professional: the risk of scratching the yellow gold case is genuine.

Yes, aftermarket straps in 6mm lug width are available from Milano Straps. All are crafted to artisanal quality standards and compatible with the PrimaLuna's lugs. You can choose from alligator, shell cordovan, calf and other materials, customising length, initials and stitching thread. The Casati Milano atelier also offers a bespoke strap creation service with personal consultation.

Lifespan depends on leather quality and use. A high-quality alligator or shell cordovan strap can last 5-7 years of regular wear, developing a fascinating patina over time. Calf leather tends to be somewhat less durable, approximately 3-5 years. Factors such as sun exposure, humidity and perspiration affect longevity. Regular maintenance (gentle cleaning and occasional conditioning) significantly extends strap life.
