Strap for Paris Royal Moonphase Blue Numerals / Brown Strap

The lug width of the Pequignet Paris Royal 9007437CG is 18 millimetres. This measurement represents the distance between the vertical attachment points on the case and is essential for identifying compatible straps. An 18mm strap fits correctly into the case lugs without excessive play or forcing. To verify the measurement, position a calliper perpendicular to the lugs, measuring from the inner centre of one lug to the inner centre of the other.

The ideal strap depends on usage and personal preference. Alligator in cognac tones represents the classical choice that emphasises the formal elegance of the timepiece. Vegetable-tanned calf leather offers a more pronounced texture and a patina that evolves over time, adding character. Cotton NATO in double weave ensures everyday versatility and ease of changing. FKM rubber is the technical solution for those who want no compromise between summer comfort and grip. All these materials in 18mm lug width are fully compatible with the 9007437CG.

Changing the strap on the Pequignet Paris Royal 9007437CG is performed via the spring bars positioned in the case lugs. Use a spring bar tool to gently press the bar downward, creating space to remove the strap end. Repeat this operation on the opposite side. To install the new strap, align the ends with the spring bar holes and press gently until you hear a click. If you do not have a spring bar tool, consult a trusted watchmaker.

Absolutely yes. In fact, a bespoke aftermarket strap in alligator, vegetable-tanned calf or high-quality NATO can transform the tactile and aesthetic experience of the timepiece. Bespoke 18mm straps are fully compatible with the case attachments of the 9007437CG. The key is to ensure that the lug width is precisely 18 millimetres and that the strap shoulder (where it seats in the lugs) is proportioned to the case thickness.

A bespoke quality leather strap, such as alligator or vegetable-tanned calf, on a daily-worn timepiece has a lifespan of 5-7 years before requiring replacement. Longevity depends on frequency of wear, exposure to moisture and perspiration, and care applied. Leather fears prolonged moisture and constant contact with sweat and chlorine. Proper maintenance—drying after water contact, avoiding intense sun exposure—and occasional treatments with specific balms significantly extend the useful life of the strap, allowing it to develop that patina characteristic of true noble materials.
