Strap for PrimaLuna Quartz 30 Stainless Steel / MOP / Bracelet

The lug width of the Longines PrimaLuna L8.112.4.87.6 is 7.00mm. This measurement was deliberately chosen to maintain correct proportions on the 30mm case. Measuring the lug width with a digital calliper between the internal attachment points is essential before purchasing a compatible strap.

For the PrimaLuna L8.112.4.87.6, alligator leather with vegetable tanning represents the ultimate choice in elegance, with its natural grain complementing the case finish. Italian calf is ideal for those seeking a patina that improves with age, while shell cordovan offers durability and a remarkable burnished finish. NATO canvas is perfect for a more contemporary aesthetic.

Changing the strap on your PrimaLuna L8.112.4.87.6 requires a dedicated tool (spring bar tool). Secure the strap on the opposite side to where you wish to insert the new one, gently compress the spring pin with the tool, and slide the old strap outward. Insert the new strap through the lug hole, then allow the spring pin to snap into place. If unfamiliar with the procedure, professionals at Casati Milano perform this service with assurance.

Any strap with a 7mm lug width is compatible with the Longines L8.112.4.87.6, provided the leather thickness is proportionate (3-4mm recommended). Milano Straps are expressly dimensioned for this width and guarantee perfect insertion into the lugs. Always verify the lug width before purchase.

A high-quality leather strap (alligator, vegetable-tanned calf, shell cordovan) typically lasts 2-4 years with conscious daily wear. Longevity depends on frequency of use, moisture exposure, and maintenance. Milano Straps include an 18-month warranty. The patina that develops over time is a desirable characteristic, not a flaw.
