Strap for PrimaLuna Quartz 26.5 Pink Gold / Diamond / White / Bracelet

The lug width of the Longines PrimaLuna L8.110.9.16.6 (L81109166) is precisely 6 mm. This is a jewellery-grade dimension, not a standard industrial measurement, requiring straps constructed with lugs shaped to millimetre tolerance. The measurement is taken by positioning a ruler between the two lug poles where the strap seats.

To complement the 18k rose gold case, we recommend alligator in cognac or chocolate brown tones for minimal elegance, or shell cordovan burgundy for those seeking patina development over time. Vegetable-tanned calf in honey or tobacco offers immediate chromatic warmth. All materials must be constructed with 6 mm lug width passants.

Strap replacement requires two tools: a spring bar tool (small metal lever) and a stable case support. Insert the tool tip into the access hole of the upper lug, gently retract the spring bar until you feel the release click, then extract the old lug. Repeat on the opposite side. Position the new strap by aligning the passants to the case lugs and press gently until the spring bar clicks into locked position.

Yes, provided the strap is specifically constructed with 6 mm lug width passants. Standard 6 mm market straps often exhibit excessive manufacturing tolerances (±0.5-1 mm), causing vertical play and instability. Milano Straps constructs passants with tolerances below 0.2 mm, guaranteeing perfect fit without case movement.

A quality artisanal alligator or shell cordovan strap lasts approximately 4-5 years with daily wear, up to 7-8 years with occasional use. Durability depends on exposure to water, perspiration, and UV rays. Vegetable-tanned leather ages more nobly but requires periodic maintenance (conditioning with natural waxes every 12-18 months). Casati Milano provides straps with an 18-month warranty against manufacturing defects.
