Strap for PrimaLuna Quartz 26.5 Stainless Steel / Pink Gold / Diamond / White

The lug width of the Longines PrimaLuna L8.110.5.19.2 is 6 millimetres. This parameter indicates the distance between the two attachment pins of the case and determines strap compatibility. It is essential to measure this dimension correctly using a calliper or ruler positioned perpendicular to the watch's axis, as it is the only relevant specification for purchasing a replacement strap, regardless of the case diameter (26.50mm in this instance).

For the Longines PrimaLuna L8.110.5.19.2, straps in black or dark brown alligator leather are recommended for formal occasions, vegetable-tanned calf leather for a more contemporary and versatile aesthetic, or cotton canvas nato for daily wear. The choice depends on your usage context and personal preference. Alligator enhances the mother-of-pearl dial without competing visually, calf leather develops natural patina over time, whilst nato offers practicality without compromising aesthetics. For the rose gold and steel case combination, neutral tones (black, grey, brown) or warm hues (burgundy, cognac) that dialogue with the rose gold are particularly effective.

Changing the strap on the Longines PrimaLuna L8.110.5.19.2 requires extracting the attachment pins from the case using a dedicated spring bar tool. Procedure: place the watch on a stable surface, insert the flat tip of the tool into the small hole beneath the pin, apply gentle pressure to compress the internal spring, extract it carefully, remove the old strap, position the new one between the lugs, and reinsert the pins into the opposite holes. This operation takes approximately 5-10 minutes if performed carefully. For those preferring professional assistance, the Casati Milano atelier offers this service complimentary with strap purchase.

All straps with a 6-millimetre lug width are compatible with the Longines PrimaLuna L8.110.5.19.2. milanostraps.it offers an extensive collection of 6mm straps in various materials: alligator, calf leather, nylon nato, shell cordovan, and rubber. Each strap is customisable in length (to accommodate different wrist sizes), stitching thread colour, and upon request, initial embossing. The standard 18-month warranty covers manufacturing defects and normal stitch wear during the first year.

A leather strap of good quality, properly maintained, provides an average lifespan of 3-5 years with daily wear. Longevity depends on factors such as material (vegetable-tanned calf leather typically outlasts alligator), frequency of use, exposure to moisture and perspiration, and preventative maintenance. Alligator or shell cordovan leather maintains superior structural integrity over time. To extend service life, allow the strap to air dry after moisture exposure, avoid prolonged direct sunlight, and apply a protective balm specific to leather every 6-12 months. The Casati Milano atelier provides precise maintenance guidance with every strap purchased.
