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

The lug width of the Longines PrimaLuna L8.115.4.98.6 is 8 millimetres. This dimension is specifically proportioned to the compact 30.50mm case and requires dedicated straps to ensure correct constructional fit, preventing misalignment between the lugs and the strap body.

We recommend alligator leather in vegetable tanning for the PrimaLuna L8.115.4.98.6, as it engages formally with the quadrant geometry and steel case. Brushed calf offers a contemporary alternative, whilst vulcanised rubber remains the ideal choice for sporty contexts whilst maintaining constructional refinement.

Strap changing occurs manually by extracting the spring bars from the lugs using a dedicated tool. Remove the old strap by gently pressing the spring bars, then insert the new strap by carefully aligning the lugs before securing. We recommend this operation at an atelier or watchmaker to prevent case damage.

Yes, provided the strap is specifically constructed for the 8mm lug width. Generic straps or those of greater width create misalignment and compromise aesthetics. Milano Straps supplies a dedicated range of artisanal 8mm straps certified compatible with your L8.115.4.98.6.

A quality alligator or shell cordovan strap properly maintained lasts between 10 and 20 years. Brushed calf requires more frequent maintenance and has a useful life between 5 and 10 years. Replacement frequency depends on daily use and seasonal maintenance—cleaning and conditioning with natural wax.
