Strap for PanoMatic Lunar Stainless Steel / Silver / Alligator / Folding

The lug width is 20 mm. This dimension is characteristic of the Pano and represents the optimal constructive compromise between the proportions of the 40 mm case and compatibility with medium to large wrists. Ensure that the new strap has lugs of exactly 20 mm to avoid free play or excessive tension on the case.

For the Pano we recommend three primary choices: vegetable-tanned alligator in medium or dark brown, which develops a golden patina and reflects light with elegance; gummed calf leather with coarse grain in black or grey, offering structural solidity and a sobriety that does not compete with the movement; NATO in pure cotton navy blue or grey, ensuring practicality and reversibility. The choice depends on usage: formal for alligator, versatile daily for calf leather, sporty-casual for NATO.

Strap replacement requires a spring bar tool (bifurcated tip instrument). Insert the tip under the upper metal lug of the strap, apply gentle pressure to retract the internal spring, then extract the pin. Repeat for the lower lug. Insert the new strap by aligning one lug first, then gently pressing until the locking click. Verify that the pin is fully seated in its grooves. Avoid forcing: excessive pressure damages the case lugs.

Yes, provided the lug width is exactly 20 mm. Quality aftermarket straps (leather, rubber, fabric) are fully compatible. Choose suppliers that guarantee precise constructive tolerances (maximum ±0.2 mm variation) and dimensionally stable materials. A poor-quality strap generates free play and accelerated wear on the case pins. Consult our 20mm catalogues for verified and certified selections.

A quality artisanal alligator or calf leather strap lasts 3-5 years in daily use, with variability dependent on climate (humidity and UV accelerate ageing) and tanning type. Vegetable tanning, though more delicate, develops a patina that increases aesthetic appeal over time. To extend durability, keep the strap dry after humidity exposure, avoid direct heat, and apply protective balm every 18 months. FKM rubber, instead, maintains structural stability for 5-7 years without maintenance.
