Frequently asked questions

What is the lug width of the Pequignet Royale Grand Sport 9030438CG?

The lug width of the Pequignet Royale Grand Sport 9030438CG is 20mm. This measurement represents the distance between the integrated case lugs, measured from outer edge to outer edge. It is an established standard in modern watchmaking and provides access to a wide range of compatible artisanal straps.

Which type of strap is most suitable for the Royale Grand Sport?

For the Royale Grand Sport 9030438CG, we recommend three primary options: alligator or vegetable-tanned leather straps for refined, durable everyday wear; NATO cotton-polyester straps for practicality and rapid interchangeability; and technical rubber straps for sporting or aquatic applications. Your choice depends on intended use and desired aesthetic outcome.

How do you change the strap on this watch?

Replacing the strap on a model with integrated lugs like the 9030438CG requires a specific tool: a spring bar remover. Gently remove the spring at the lower lug, slide out the old strap, insert the new one, and reinserting the spring. If you are not experienced, we recommend consulting a professional watchmaker or Atelier Casati Milano for safe replacement.

What is the difference between an original Pequignet strap and a compatible aftermarket strap?

Original Pequignet straps are specifically dimensioned and finished for the model. Compatible aftermarket straps from Milano Straps maintain the same lug width (20mm) and artisanal build quality, yet allow material, colour, and finish customisations rarely found in official catalogues. Both are fully functional; your choice depends on aesthetic preferences and desire for uniqueness.

How long does a natural leather strap last on a watch like the 9030438CG?

The lifespan of a natural leather strap ranges from 3 to 7 years depending on tanning method, daily use, and environmental conditions (humidity, sun exposure). Vegetable-tanned leather typically lasts longer than chrome-tanned leather, developing a fascinating patina over time. Proper maintenance—avoiding prolonged water contact and direct sunlight—significantly extends strap longevity.
