The Royale 300 9051443CN, seen from the bench

The Pequignet Royale 300 9051443CN is an independent French watchmaking statement featuring a 43mm stainless steel case and the in-house Calibre Royal movement with hours, minutes, small seconds, and power reserve indicator. The 20mm lug width integrates with the case architecture to maintain classical proportions and stylistic coherence. Brushed surfaces on the case communicate solidity without ostentation, positioning this reference in universal wearability while maintaining a mature visual impact.

Frequently asked questions

What is the exact lug width of the Pequignet Royale 300 9051443CN?

The lug width of the Pequignet Royale 300 is precisely 20mm. This dimension is integrated into the case architecture, ensuring balanced proportions between the 43mm case and strap. Always measure between the two inner attachment points to confirm compatibility with aftermarket straps.

Which strap material is best suited for the Royale 300?

The Royale 300 pairs ideally with authentic alligator featuring vegetable tanning, which amplifies formal sophistication through naturally irregular grain. Vegetable-tanned calf leather offers organic ageing and developable patina over time. For sports contexts, Cordura NATO maintains formality whilst introducing versatility. FKM rubber allows contemporary interpretation without compromising wearability.

How do I change the strap on the Pequignet Royale 300?

The Royale 300 uses standard 20mm strap attachments. Use a spring bar tool to gently depress the retaining pins. Insert the flat tip into the slot on the lug and release the spring tension, then remove the attachment. Repeat on the opposite side. To install the new strap, align the attachments with the holes and press until you feel the spring click into position.

Are 20mm aftermarket straps truly compatible with the Royale 300?

Yes, completely. The Royale 300 does not employ proprietary attachments; the 20mm lug width is an industry standard. Any strap measuring 20mm in width (verifiable by measuring its upper extremity) installs correctly. However, prioritise quality straps: the case deserves materials that respect its architectural integrity.

How long does a leather strap last on a daily-worn Royale 300?

An authentic shell cordovan strap with vegetable tanning, worn daily, typically lasts 3–5 years before showing significant wear. Standard calf lasts 2–4 years. Longevity depends on sweat exposure, humidity and wearing frequency. Authentic alligator, less sensitive to hydration, tends to last longer. FKM rubber offers superior resistance (5–7 years), whilst Cordura NATO is virtually eternal.
