Frequently asked questions

What is the exact lug width of the Pequignet Royale Grand Sport 9030443CN?

The <a href="/pages/termine-glossario/misura-ansa">lug width</a> of the Pequignet Royale Grand Sport 9030443CN is 20mm. This dimension, particularly common in high-end sports models, allows for versatile pairing with an extensive range of artisanal straps, whilst maintaining optimal visual proportions relative to the 44mm tonneau case.

What is the most suitable strap for the Royale Grand Sport 9030443CN?

For the Royale Grand Sport 9030443CN, we recommend an <a href="/pages/termine-glossario/alligatore">alligator</a> strap with <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a> in deep tones—black, dark brown, midnight blue—to emphasise the refined-sporty character of the case. Alternatively, a textured calf leather with stainless steel <a href="/pages/termine-glossario/deployante">deployante</a> clasp balances luxury with technical functionality. For intensive use, heavy-canvas NATO is the most versatile choice.

How do I replace the strap on a 20mm lug width watch?

The operation requires a spring bar removal tool. Position the watch face-down on a soft surface. Insert the forked tip of the tool into the spring retention notch, pressing gently inward to free the lug from its seat. Repeat on the second pin. Installation of the new strap reverses this procedure: thread the pins into the seats, ensuring the retention spring clicks into position. Avoid forcing to prevent damage to the case lugs.

Are Milano Straps compatible with the 20mm lug width on the Royale Grand Sport?

Yes, all <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-20mm">20mm straps</a> in our catalogue are manufactured to precise tolerances, guaranteeing perfect compatibility with the Pequignet Royale Grand Sport 9030443CN and other models featuring the same lug width. Each strap undergoes testing before dispatch. For customisation requests or specific adaptations, contact Atelier Casati Milano directly via email.

How long does a leather strap last on a sports watch like the Royale Grand Sport?

Leather strap longevity depends upon usage patterns, climate, and frequency of wear. With moderate use—four to five days per week—and proper maintenance, a <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a> or quality alligator strap may last three to five years before showing significant wear. Vegetable-tanned calf typically yields a slightly shorter lifespan of two to four years. Factors such as humidity, direct sunlight exposure, and water contact accelerate ageing. The patina that develops is not deterioration, but natural aesthetic enrichment of the leather.
