Pequignet
Rue Royale 9010437CG— lug 18mm

The Pequignet Rue Royale 9010437CG features a lug width of 18mm. This is the distance between the two pins that attach the strap to the case. An 18mm lug width is typical of classical French watchmaking and allows for straps of generous thickness whilst maintaining balanced proportions on the 42mm case.

For the 9010437CG, an alligator strap with vegetable tanning offers the highest aesthetic balance, amplifying the refined character of the stainless steel case. Alternatively, a high-quality vegetable-tanned calf develops a natural patina over time. For a more sporty approach, a robust canvas NATO strap or dark FKM rubber maintains proportion without functional compromise.

The Pequignet Rue Royale 9010437CG uses straight pins without quick-release mechanism. To replace the strap: (1) remove the pins using a spring bar tool (small implement with curved end), (2) gently extract the pins from their housings in the case, (3) insert the new strap aligning the side holes with the pins, (4) reinsert the pins until they click into place. Proceed with caution to avoid scratching the case.

Yes, any strap with an 18mm lug width is fully compatible with the 9010437CG. Artisanal aftermarket straps often offer superior build quality compared to the original integrated bracelet, allowing for personalised material selection (alligator, shell cordovan, vegetable-tanned calf) and chromatic matching. Compatibility is guaranteed by lug width standardisation.

A high-quality leather strap (alligator, shell cordovan, vegetable-tanned calf) lasts an average of 3–7 years on a daily-worn watch, depending on climate, humidity and cleaning frequency. Vegetable tanning develops a natural patina that preserves the leather structure over time. To extend lifespan, avoid prolonged exposure to high humidity and apply leather conditioner every 6–12 months. Canvas NATO straps last longer (5–10 years), whilst FKM rubber lasts 2–4 years before losing elasticity.
