Strap for PrimaLuna 30.5 Quartz Moonphase Stainless Steel / MOP / Bracelet

The lug width of the Longines PrimaLuna L8.115.4.87.6 is 8mm. This measurement is essential when selecting a compatible strap. Use a digital calliper to measure between the inner shoulders of the lugs, maintaining a tolerance of ±0.2mm. Milano Straps stocks a comprehensive range of 8mm straps in premium materials.

Given the delicate proportions and diamond-set bezel, we recommend alligator in coloured tones (sage green or burgundy), vegetable-tanned calf leather in black or brown, or shell cordovan which develops a magnificent patina over time. Avoid thick or bulky straps: the PrimaLuna's elegance resides in proportional harmony, and the strap must respect this principle.

Strap changes are accomplished via spring bars—small spring-loaded pins that connect the strap to the case lugs. Using a dedicated spring bar tool, press the pin inward to release one end, then repeat on the opposite side. The operation is straightforward but requires care on a case as refined as this one.

Any strap measuring 8mm in width is compatible with this model. Milano Straps offers 8mm options in alligator leather, vegetable-tanned calf, shell cordovan, and technical rubber, with customisation available for length, initials, and thread colour. We guarantee construction precision and finishing at the level of the original strap.

A premium leather strap (alligator, vegetable-tanned calf, shell cordovan) typically lasts 3–5 years with daily wear, extending to 7–8 years with rotation between multiple straps. Longevity depends on humidity, sun exposure, and buckle wear. Milano Straps provides an 18-month warranty on bespoke straps created in the Casati Milano atelier.
