Strap for PrimaLuna Quartz 26.5 Stainless Steel / Silver - Roman / Bracelet

The lug width of the Longines PrimaLuna L8.120.4.71.6 is 6mm. This measurement represents the distance between the inner lugs of the case and is critical for the compatibility of any aftermarket strap. Always verify this dimension with a calliper before ordering.

Genuine alligator in cognac or dark brown tones is the most harmonious choice for the PrimaLuna. However, vegetable-tanned calf leather offers superior durability and evolving patina over time. Your choice depends on intended use and personal preference. For formal environments, alligator; for versatile daily wear, calf leather.

Strap replacement requires a spring bar tool (a specialised implement with a soft tip). Insert the flat end under the lug of the case and apply gentle downward pressure to release the internal spring, then carefully remove the spring bar. Repeat on the other side. For installation of the new strap, reverse the process. If you lack experience, consult a professional watchmaker.

Yes, provided the lug width is exactly 6mm and the total strap width does not exceed 20mm (aesthetic limit for this case). Full-grain leather straps of 3.5 to 4mm thickness guarantee the best visual proportions. Verify the technical specifications from the seller before purchase.

A quality leather strap (alligator, vegetable-tanned calf, or shell cordovan) maintains optimal functionality for 5-7 years of moderate daily use. Longevity depends on sun exposure, humidity, frequency of changes, and care regimen. Once yearly, apply natural mink oil to preserve flexibility. At the end of its service life, the original lug remains intact and the strap can be replaced whilst preserving the timepiece.
