Strap for PrimaLuna Quartz 34 Stainless Steel / Diamond / MOP / Bracelet

The lug width of the Longines PrimaLuna L8.114.0.87.6 is 9mm. This measurement is specific to this model and must be verified with a digital calliper positioned between the two lugs of the case. It is essential to measure correctly before purchasing an aftermarket strap, as 9mm is not a 'standard' lug width and is easily confused with 8mm or 10mm lugs.

The choice depends on usage and personal preference. For classical elegance, we recommend alligator with natural grain or calf leather with vegetable tanning. For durability and luxury, shell cordovan offers substantial solidity and a lustrous appearance. For modern versatility, a linen or FKM rubber NATO strap guarantees practicality and breathability. Casati Milano personalises every choice based on your dial colour and lifestyle.

The strap is changed using a spring bar removal tool. Position the watch on a soft surface, locate the two small holes at the ends of the case where the spring bars are inserted, and apply gentle pressure to slide the spring bars out of their housings. Repeat the procedure on the other side. When installing the new strap, reverse the process, ensuring the spring bars are fully seated. If you are unsure, contact Casati Milano.

Yes, provided it has been manufactured with a 9mm lug width. Quality aftermarket straps, such as those made by milanostraps.it, offer a far wider range of materials and finishes than original bracelets. Always verify that the lug width is exactly 9mm and that the spring bars are correctly sized to fit into the lugs of your case.

Durability depends on material and usage. Quality vegetable-tanned calf leather lasts 3-5 years of daily wear before showing signs of wear. Alligator is more durable, with an estimated lifespan of 5-7 years. Shell cordovan can exceed 10 years due to its structural density. Rubber and synthetic materials last 3-4 years. Casati Milano offers an 18-month warranty on all bespoke straps, covering manufacturing defects.
