Strap for PrimaLuna Automatic 26.5 Yellow Gold Diamond Funky MOP

The lug width of the Longines PrimaLuna L8.111.7.83.6 is 6mm. This measurement corresponds to the internal distance between the two metal pins that attach the case to the strap. To verify, remove your current strap and measure the space between the metal attachments on the case.

For the PrimaLuna, we recommend cognac brown alligator or vegetable-tanned calf leather, which enhance the precious nature of the yellow gold case. For formal occasions, choose leather with rich patina; for daily wear, opt for fine grain and soft feel. A silk NATO or FKM rubber strap represents a contemporary and versatile alternative.

To change the strap, use a dedicated springbar tool or consult a watchmaker. Position the strap sideways beneath the case and gently push the small vertical metal pin inward using the tool. When the pin retracts, the strap comes free. Repeat on the opposite side. Install the new strap by reversing the procedure.

Yes, any strap with a 6mm lug width is compatible with your Longines PrimaLuna L8.111.7.83.6. Milan Straps artisanal straps offer complete customisation: choice of leather, width, initials, and stitching, ensuring perfect fit and construction quality consistent with your case.

A quality leather strap, with proper maintenance, lasts an average of 3-5 years of daily wear. Longevity depends on tanning method (vegetable tanning lasts longer than chrome), frequency of wear, and periodic rest of the leather. Rotating multiple straps significantly extends overall durability and maintains comfort.
