Strap for Royale Grand Sport Moonphase Silver Numerals / Black Strap

The lug width of the Pequignet Royale Grand Sport 9030433CN is precisely 20mm. This measurement is calculated from the internal distance between the two lugs on the case. Verifying this dimension before purchasing an aftermarket strap is essential to ensure perfect fit and eliminate any lateral play between the strap and the lugs.

For the 9030433CN, we recommend vegetable-tanned alligator in cognac or dark brown tones, which emphasises the French heritage of the timepiece and the proportionality of the 44mm case. Alternatively, NATO canvas in grey-blue for a more sporty approach, or burgundy shell cordovan for those seeking a patina that evolves with time. FKM rubber is ideal for humid environments whilst maintaining aesthetic balance.

Strap replacement on the 9030433CN is performed by unscrewing the spring bars (spring-loaded pins) that connect the strap to the case. Use a dedicated spring bar tool to avoid damage to the case and lugs. Position the tool in the lateral groove of the pin, apply gentle pressure to release the spring mechanism, and extract the pin. Repeat on the opposite side. Install the new strap following the reverse procedure, verifying that the pins click securely into place.

Yes, aftermarket straps with a 20mm lug width are fully compatible with the 9030433CN, provided they respect the specified width. On milanostraps.it you will find a selection of artisanal 20mm straps in various materials: alligator, calf, NATO, and rubber. Each strap is crafted with specific attention to the case proportions and construction quality of French horology.

A quality leather strap (vegetable-tanned alligator or shell cordovan) on the 9030433CN typically lasts 3 to 5 years under regular daily wear, with variance depending on climate, sun exposure, and leather type. Vegetable tanning develops a natural patina that improves over time, whilst shell cordovan gradually darkens. Periodic maintenance (cleaning with a damp cloth, annual conditioning) significantly extends the strap's useful life.
