Strap for PrimaLuna Automatic 30 Yellow Gold MOP

The lug width of the Longines PrimaLuna L8.113.6.87.6 is 8mm. This measurement is specific to this model and is essential for ensuring strap compatibility. To verify, measure the space between the two lugs of the case using a digital calliper: the value should be between 7.8mm and 8.2mm for a strap to be considered suitable.

For a Longines PrimaLuna L8.113.6.87.6 in yellow gold, dark or medium brown alligator represents the choice of maximum prestige, amplifying the perception of luxury. Italian calf leather in a deep burgundy tone creates sophisticated and versatile contrast. For formal evening wear, a classic black calf remains the universal choice. Alternatively, natural cream-coloured calf in vegetable tanning transforms the watch into a summer statement piece.

To change the strap, use a dedicated tool (spring bar tool) to remove the lateral pins that secure the strap to the case lugs. Work carefully to avoid scratching the yellow gold. Insert the new 8mm strap, ensuring the pins enter the lugs perfectly. Verify that the strap is positioned correctly and has no lateral play. If your strap features a deployante clasp, ensure it has been adjusted to the correct wearing length.

Yes, it is entirely possible and recommended. A quality aftermarket strap, crafted in alligator, calf, rubber or other materials with an 8mm lug width, is not only compatible but allows you to vary the style and character of the watch according to different occasions. Milano Straps offers ready-to-ship 8mm straps and the option of bespoke creations at the Casati Milano atelier, with personal selection of leathers and an 18-month warranty.

A quality calf or alligator strap, subjected to vegetable tanning, maintains optimal performance for 5-7 years of regular use. Lifespan depends on frequency of use, exposure to moisture, leather quality and maintenance care. An excellently crafted leather strap, such as those created by Milano Straps, develops a noble patina over time that increases its aesthetic appeal. The 18-month warranty on bespoke straps from Casati Milano covers construction defects and guarantees a solid foundation for extended use.
