Strap for Royale 300 Black-Blue / Rubber

The Pequignet Royale 300 9051443/30 features a lug width of 20 millimetres. This measurement is determined by the distance between the two metal pins that secure the strap to the case lugs. To verify, measure the width between the pins using a digital calliper, or consult the official technical specifications from Pequignet. Do not confuse lug width with the case diameter.

For the Royale 300 9051443/30, we recommend three primary options: (1) full-grain vegetable-tanned leather in cognac or medium brown tones, which develops natural patina over time; (2) alligator or Nile crocodile in deep black or burgundy for formal refinement; (3) vegan rubber with medium grain for humid environments and intensive use. Your choice depends on intended context and personal colour preference.

To change the strap on a 20mm lug-width watch: (1) obtain a spring bar remover tool; (2) position the tool under the pin and gently lift to extract it; (3) remove the old strap; (4) align the new strap and insert it through the case lugs; (5) reinsert the pin, ensuring it is fully seated in both lug holes. If inexperienced, consult a qualified watchmaker to prevent case damage.

Yes, any high-quality strap with 20mm lug width is mechanically compatible with the Royale 300 9051443/30, provided it is constructed from noble materials with refined finishing. Specialist manufacturers such as Milano Straps produce bespoke straps that respect the watch's proportions and maintain the French house's aesthetic standards. Always verify technical specifications before purchase to confirm exact lug width compatibility.

A full-grain vegetable-tanned leather strap, worn daily, maintains structural integrity for 3–5 years before displaying visible wear. Longevity depends on frequency of use, exposure to moisture and perspiration, and maintenance (gentle cleaning with soft cloth, avoiding prolonged submersion). Alligator and shell cordovan straps, being denser, can endure 5–8 years. Rubber straps exhibit similar lifespan to leather but offer superior moisture resistance.
