Strap for Prestige Gold Cushion 18

The lug width is 20mm. This measurement represents the distance between the two lugs on the case where the strap is attached. It is a specific standard for Longines dress models with compact proportions, ensuring compatibility with all our 20mm straps.

A natural alligator or superior quality calf leather strap is the most harmonious choice. Brown or black alligator enhances the luminosity of the white gold case, while aged vegetable-tanned calf with natural patina amplifies the vintage aesthetic. Avoid excessively thick straps or decorative elements—this Longines demands visual restraint.

Use a spring bar removal tool (available online as a professional kit). Position the watch on a clean surface, gently press one spring bar lever to compress the spring, remove the old strap, then insert the new one by aligning the holes with the case lugs. Ensure the spring bar is fully seated before releasing pressure.

Absolutely. Any strap with a 20mm lug width is compatible with this model. Milan Straps artisanal straps are specifically created for this measurement, featuring premium materials (alligator, shell cordovan, vegetable-tanned calf) and refined finishing. They guarantee quality superior to generic straps.

Lifespan depends on material and usage. Quality alligator with vegetable tanning resists 5-8 years with routine maintenance (periodic cleaning, protection from excess moisture). Aged calf lasts 4-6 years. Shell cordovan, given its natural resistance, can exceed 10 years. The patina developing over time is a desired characteristic, not a defect.
