Strap for Paris Royal Moonphase Blue Numerals / Black Strap

The lug width of the Pequignet Paris Royal 9007437CN is 18 millimetres. This measurement is essential for compatibility with aftermarket straps and should be verified by measuring the perpendicular distance between the case lugs using a digital calliper or precision ruler.

For the Paris Royal 9007437CN, we recommend an authentic alligator strap or vegetable-tanned leather with natural tanning. Alligator enhances the refinement of the brushed steel case and ensures longevity; vegetable-tanned calf develops dynamic patina over time. Valid alternatives include vulcanised rubber straps for sporting contexts and canvas NATO straps for everyday versatility.

To change the strap, first remove the spring bar (or strap lug) from one side using a dedicated tool or thin blade, keeping the case secure. Extract the spring bar from the old strap, align it with the case lug, and insert the new strap until the spring bar clicks firmly into place. Repeat for the opposite side. We recommend consulting a professional watchmaker to avoid damage.

Yes, the Paris Royal 9007437CN is compatible with any quality strap featuring an 18mm lug width, regardless of brand. We recommend selecting straps crafted from durable materials (alligator, calf, vulcanised rubber) and verifying that the attachment finish suits the case lug profile.

The longevity of a leather strap depends on material: an authentic alligator strap lasts 8–12 years with regular maintenance; a vegetable-tanned calf strap lasts 4–7 years. Vulcanised rubber has a lifespan of 3–5 years. Factors such as sun exposure, humidity, frequency of wear and perspiration accelerate degradation. Regular cleaning and treatment with water-repellent cream significantly extend longevity.
