Strap for PrimaLuna Automatic 26.5 Yellow Gold Diamond Leather Arabic

The lug width is exactly 6 millimetres, a particularly compact measurement characteristic of this refined dress watch. To verify, measure the perpendicular distance between the two internal lateral lugs. Only straps specifically designed for 6mm will fit correctly without creating play or tension on the yellow gold case.

American alligator from the Mississippi is the benchmark choice: its anatomically fine grain reflects light in a way that elevates the yellow gold, offering supreme elegance. Shell cordovan remains an excellent alternative for those seeking developed patina over time, whilst vegetable-tanned calf suits summer contexts whilst maintaining formal rigour. Avoid standard 8-10mm straps, which would visually unbalance the proportions.

Remove the watch from your wrist. Using a dedicated tool (spring bar removal tool or lug pusher), gently lever out the lugs from the case shoulders, one at a time. Once both lugs are extracted, the old strap will separate. Align the new strap holes with the lugs and reinsert them with gentle, deliberate movement until you feel the locking click. Do not force: yellow gold is a soft metal.

A quality leather strap—whether alligator, shell cordovan or vegetable-tanned calf—typically lasts 3-5 years with moderate daily wear. Longevity depends on sun exposure, perspiration and frequency of use. Alligator ages beautifully, developing a distinctive patina. To extend lifespan, protect from prolonged rain and excessive humidity, and occasionally apply natural wax to renew leather hydration.
