Strap for PrimaLuna Quartz 30 Stainless Steel / Silver - Roman

The lug width of the Longines PrimaLuna L8.112.4.71.2 is 7 millimetres. This delicate measurement is specific to small-diameter feminine models (30mm) and is essential for strap compatibility. Measurement is taken by calculating the distance between the centre of the upper lug and the centre of the lower lug, at the precise point where the original strap is inserted.

For the Longines PrimaLuna L8.112.4.71.2, the most aesthetically coherent choice is a calf leather with vegetable tanning, which develops a rich patina over time, or an alligator with natural grain, guaranteeing longevity and tactile elegance. For versatile use, grey tortoiseshell or cognac brown alligator integrates perfectly with the steel case. Alternatively, a NATO strap in cotton canvas offers daily practicality, though the constructive rigour of the watch merits a deployante closure.

The strap on the Longines PrimaLuna L8.112.4.71.2 is replaced by removing the spring bars connecting the strap to the case. Using a specific tool, apply gentle inward pressure to release the return spring, then extract the bar. Insert the new bar into the lower lug, position the strap and push the bar until it locks. The operation should be performed with extreme care to avoid scratching the steel case.

Yes, it is possible to use aftermarket straps provided they strictly adhere to the 7-millimetre lug width specification. A strap of different width (18mm, 20mm) will not fit correctly. We recommend always verifying the strap's technical specifications before purchase. On milanostraps.it you will find 7mm straps specific to this model, with customisation options and extended warranty.

The lifespan of a quality leather strap depends on material and usage. A calf with vegetable tanning maintains functionality and aesthetics for 5–7 years with moderate daily use. Alligator, owing to its more robust fibrous structure, can last 8–10 years. Regular maintenance (protection from stagnant water, drying after accidental contact) significantly extends useful life. Casati Milano straps include an 18-month warranty against manufacturing defects.
