Frequently asked questions

What is the lug width of the Longines PrimaLuna L8.113.8.87.2?

The lug width (ansa) of the Longines PrimaLuna L8.113.8.87.2 is exactly 8mm. This is a micro-watchmaking measurement, characteristic of compact Swiss feminine models. Measure internally between the two metal lugs of the case to verify compatibility of any aftermarket strap. A 9mm or 7mm strap would not insert correctly, causing structural play and premature wear.

Which strap is most suitable for the Longines PrimaLuna in rose gold?

For the PrimaLuna's rose gold, we recommend alligator with vegetable tanning (medium brown or black) or shell cordovan in burgundy. Alligator develops noble patina over time, whilst shell cordovan matures into liquid red-black. Avoid synthetic leather straps: rose gold deserves natural leathers that age consciously. Minimum recommended quality: full-fleur alligator or first-choice shell cordovan.

How do you change the strap on the Longines PrimaLuna L8.113.8.87.2?

Strap replacement on the PrimaLuna follows standard procedure: use a spring bar tool to apply gentle pressure to one of the metal springs (spring bars) that secure the strap to the lugs. Retract the spring downward with the tool, then remove the strap. When inserting a new 8mm strap, ensure the spring clicks into position with a crisp 'click' on both sides. A 30mm rose gold case demands care: precious material does not forgive scratches. If inexperienced, consult a specialist craftsman.

Can aftermarket straps be used on this model?

Yes, provided they respect the exact 8mm lug width. Geometric compatibility is guaranteed with any strap constructed to this measurement: alligator, calf, shell cordovan, vulcanised rubber. Final quality depends on construction choices (vegetable vs industrial tanning, leather thickness, buckle finishing). Milano Straps supplies 8mm straps customisable in dimensions, initials and premium finishes compatible with the watch's elegance.

How long does a natural leather strap last on the Longines PrimaLuna?

Durability depends on leather quality and daily use. First-choice alligator or shell cordovan with vegetable tanning lasts 3-5 years in daily wear (considering replacement every 3-6 months for uniform wear). Natural leather deforms progressively and stitching wears: this is not a defect, but the effect of patina. Milano Straps supplies straps with 18-month warranty. After this period, you can have the strap regenerated by a specialist (re-stitching, leather re-treatment) to extend life by another 2-3 years.
