Strap for Royale 300 Blue / Rubber

The lug width of the Pequignet Royale 300 reference 9050473/36 is 20mm. This measurement defines the distance between the two lugs where the strap attaches to the case. A 20mm strap ensures precise fit, which is essential both for secure wearing and for maintaining the overall aesthetic balance of the watch.

The ideal strap depends on context. For formal elegance: natural alligator with vegetable tanning, which develops character over time whilst remaining coherent with the brushed steel case. For robust daily wear: calf with pronounced texture or FKM rubber. For maximum versatility: quality military-grade canvas NATO. Each option requires a 20mm lug width and a steel deployant clasp in brushed finish to preserve the proportions of the 43mm case.

Changing the strap on the Royale 300 requires a spring bar tool—a specialised implement designed to compress the elastic pins that retain the lugs. Work on a soft, flat surface to avoid scratches. Extract each lug with controlled rotational movement, position the new strap carefully, reinsert the lugs with millimetre precision, and verify that the attachment is secure. If you have never performed this operation, consult a qualified watchmaker.

Any strap with a 20mm lug width is constructively compatible. Recommended options include those with verified artisanal quality: genuine alligator, hammer-textured calf with selected tanning, certified military-grade NATO, or structured FKM rubber. The strap must mount a deployant clasp to accommodate the wrist without requiring multiple adjustments, and feature lateral keepers dimensioned to avoid excessive bulk at the case shoulders.

A quality leather strap (alligator or calf) worn daily on a Pequignet Royale 300 typically lasts 3–5 years before replacement becomes necessary, depending on humidity exposure, perspiration, and UV light. Vegetable-tanned leather maintains structural integrity longer than industrial tanning. Shell cordovan, if maintained with minimal care, can last 7–10 years whilst developing a desirable patina. Rubber and NATO straps offer superior longevity (5–8 years) under normal wearing conditions.
