Strap for PrimaLuna 34 Automatic Moonphase Stainless Steel / Blue MOP

The lug width of the Longines PrimaLuna L8.126.0.97.2 is 8 millimetres. This is a non-standard measurement in contemporary watchmaking, required by the proportion of the 34mm case. To verify it, measure the distance between the internal lugs using a digital calliper positioned perpendicularly.

For the PrimaLuna, we recommend an alligator strap in navy blue or chocolate tones, or vegetable-tanned calf leather that develops patina over time. Alligator maintains formal elegance, whilst calf leather offers versatility. For humid environments, high-density natural rubber guarantees practicality without compromising design. Your choice depends on use context and dial colour.

The strap is changed by removing the spring bars securing the lugs to the case. Use a dedicated spring bar tool, positioning the bifurcated tip underneath the spring bar and applying controlled pressure inward until it detaches. Align the new strap's spring bars with the lug holes, then press until they click into place. Consult our atelier for assistance if inexperienced.

Yes, provided the aftermarket strap is specifically designed for 8mm lug width. Many straps on the market are manufactured for standard gauges (16, 18, 20mm), making them incompatible. Milano Straps produces 8mm straps verified for the PrimaLuna, guaranteeing compatibility and artisanal quality with noble leathers and customisable stitching.

A quality leather strap (alligator, vegetable-tanned calf, shell cordovan) typically lasts 3-5 years with regular maintenance. Longevity depends on frequency of wear, moisture exposure and care applied. A strap subjected to intense daily wear or humid conditions may require replacement sooner. Casati Milano's 18-month warranty covers manufacturing defects.
