Strap for PrimaLuna Automatic 30 Yellow Gold Diamond Leather Funky MOP

The lug width of the Longines PrimaLuna L8.113.7.83.2 is 8mm. This measurement is critical for aftermarket strap compatibility and reflects the proportion of the 30mm diameter case. Measurement is performed using a digital calliper in the internal space between the two lugs.

The best strap depends on use and personal preference. For formal elegance, we recommend vegetable-tanned alligator in dark cognac or Swiss black calf. For longevity and patina development, vegetable-tanned shell cordovan is ideal. For summer versatility, light blue calf or Egyptian cotton NATO fabric works well. All 8mm straps available on milanostraps.it are 100% compatible with your watch's factory lugs.

Remove the strap using a spring bar remover tool (typically supplied with Longines watches or available from milanostraps.it). Insert the flat end of the tool into the lateral holes of the lugs, release the internal spring of the bar, and remove the old strap. To install the new 8mm strap, align the passants with the lugs and press until you feel the spring click into place. No additional tools are required.

Yes, completely compatible. The PrimaLuna is factory-fitted with standard removable spring bars, and any strap with an 8mm lug width will fit perfectly. Artisanal straps from milanostraps.it and Casati Milano atelier are constructed specifically for this width, guaranteeing precise fit without lateral play.

Leather strap longevity depends on frequency of use, material quality, and maintenance. Vegetable-tanned leather (alligator, calf, shell cordovan) has an average lifespan of 3-4 years with regular wear. Casati Milano atelier provides an 18-month warranty on all artisanal straps, covering manufacturing defects and premature wear. Regular maintenance (cleaning and conditioning every 6 months) can extend strap life to 5-6 years.
