Strap for PrimaLuna Quartz 23 MOP

The lug width of the Longines PrimaLuna L8.109.4.87.6 is precisely 6.00mm. This measurement must be taken between the inner walls of the lugs, excluding any gaskets or protective materials. Accurate measurement is critical, as even minor deviations can compromise the strap's fit on the watch case.

For a watch with such delicate lugs, we recommend alligator leather in vegetable tanning, which provides a three-dimensional texture that complements the polished case and develops a captivating patina over time. Shell cordovan calf is an excellent alternative for those seeking superior structural rigidity. Avoid heavy synthetic materials that would create visual imbalance on the watch's diminutive proportions.

Remove the strap using a spring bar tool (typically provided with artisanal straps) or apply gentle pressure manually to the lug spring from inside the case. The spring must slide out of the lug hole smoothly. Keep the watch horizontal during removal and work with care to avoid scratching the stainless steel case. Attachment follows the reverse procedure.

Yes, Milano Straps offers a comprehensive collection of 6mm-compatible artisanal leather straps, including alligator, calf, and technical materials.

Durability depends on material quality and usage conditions. Artisanal alligator leather with vegetable tanning typically lasts 3-5 years with daily wear, developing an increasingly refined patina. Natural calf leather offers slightly shorter longevity (2-4 years), while soft aniline leathers require more frequent maintenance. Milano Straps guarantees 18 months on Casati Milano bespoke straps, regardless of natural wear.
