Strap for PrimaLuna Automatic 26.5 Stainless Steel / Diamond / Silver - Roman / Bracelet

The lug width of the Longines PrimaLuna L8.111.0.71.6 is precisely 6mm, a specification that reflects the delicate proportions of the 26.50mm case. This dimension is essential for maintaining visual balance between case and strap. You can verify it by inserting a digital calliper between the lugs at the widest point.

For the PrimaLuna, we recommend straps in alligator leather with vegetable tanning, vegetable-tanned calf leather dyed in aniline, or shell cordovan for those seeking a noble patina. For a sportier approach, robust calf leather with pronounced grain maintains the case's refined character. Selection depends on intended use and personal colour preference.

Strap replacement is performed via spring bars, small springs concealed within the lugs. Use a dedicated spring bar tool to compress the spring and extract the old strap, then insert the new strap by securing the spring bars into the corresponding lugs. This operation requires precision to avoid damaging the lugs. If inexperienced, consult an authorised service centre.

Yes, any strap with a certified 6mm lug width is compatible. At milanostraps.it you'll find a curated selection of ready-to-ship straps in this width, customisable in length, initials and stitching thread. For a bespoke result, the Casati Milano atelier creates custom straps with direct selection of leather.

Leather strap durability depends on workmanship quality and daily wear. An alligator or shell cordovan strap can last 5-7 years with ordinary maintenance; well-crafted vegetable-tanned calf reaches 3-5 years. Exposure to excessive humidity, intense heat or prolonged perspiration reduces longevity. Casati Milano straps include an 18-month warranty.
