Strap for PrimaLuna Quartz 26.5 Stainless Steel / Yellow Gold / MOP / Bracelet

The lug width of the Longines PrimaLuna L8.110.5.93.6 is 6 millimetres. This is a non-standard dimension, specific to compact feminine timepieces. To verify compatibility, measure the distance between the two lugs of the case using a digital calliper, excluding the metal flanges. It is critical to purchase a strap of the correct length relative to your wrist and the 6mm lug width.

The best strap depends on your intended use. Alligator with natural tanning offers elegance and lasting durability, ideal for formal occasions. Vegetable-tanned calf leather provides softness and develops an authentic patina over time. For a dark blue dial, a cognac or Tuscan brown calf creates chromatic harmony. For more dynamic use, polished shell cordovan creates sophisticated optical effects. Textured rubber remains the most versatile choice for daily bimodal wear.

To change the strap, obtain a spring bar tool. Position the watch on a soft surface. With a gentle motion, insert the flat tip of the tool under the dual-ended spring bar, compressing it towards the interior. When the spring compresses, the opposite end releases from the case lug. Repeat the procedure from the other end. Install the new strap by reversing the process. Be careful not to scratch the case during the operation.

Any strap with a 6 millimetre lug width is compatible with the PrimaLuna L8.110.5.93.6. Because 6mm is a non-standard measurement, options are limited compared to more common lug diameters. Milano Straps offers bespoke artisan straps in 6mm alligator, calf, shell cordovan and rubber. The Casati Milano atelier creates custom-made straps with personal leather selection and personalised stitching.

The lifespan of a leather strap depends on the material and use. A vegetable-tanned alligator strap typically lasts 4-6 years with moderate use and regular maintenance. Vegetable-tanned calf leather has a similar lifespan, whilst shell cordovan, due to its structural density, can last 5-7 years. Rubber tends to degrade more slowly at the edges but remains functional for 3-5 years. Regular maintenance—drying after moisture exposure and conditioning with natural creams every 6-12 months—significantly extends the strap's life.
