Strap for Royale 300 Blue-Black / Canvas

The lug width of the Pequignet Royale 300 9051473CN is 20mm. This measurement is taken as the internal distance between the lugs on the case, and it is essential for selecting a compatible strap. An undersized strap will create unwanted lateral gaps, while an oversized strap will not properly insert into the lugs, compromising the watch's stability on the wrist.

The best strap depends on intended use and aesthetic preferences. For formal contexts, we recommend an alligator strap with vegetable tanning in black or brown, which emphasises the design's severity. For daily wear prioritising comfort, vegetable-tanned calf leather is ideal as it develops character over time through natural patina. For a sportive setting, a NATO strap in dense nylon or heavy cotton accentuates the watch's technical vocation. For aquatic environments, a rubber strap with pronounced grain texture ensures grip and moisture resistance.

Changing a strap on a watch with 20mm lugs like the Royale 300 requires a spring bar tool. Position the watch with the case upward, locate the lugs on both sides of the case, and use the flat-head screwdriver of the spring bar tool to gently compress the internal spring of the lug. Once compressed, the lug slides horizontally, freeing itself from the old strap. Repeat the operation on the opposite side, then insert the new strap, verifying that the lugs fully snap into position.

Yes, any strap with a 20mm lug width is compatible with the Royale 300 9051473CN, provided the overall width of the strap does not exceed the visible zone between the flanges. MilanoStraps offers a curated selection of artisanal 20mm straps manufactured from premium materials (alligator, calf, shell cordovan, technical rubber) and produced by small ateliers to ensure construction precision and tactile quality superior to industrial alternatives.

The lifespan of a leather strap depends on material and usage conditions. An alligator or vegetable-tanned calf strap worn daily typically lasts 3–5 years before requiring structural replacement. Prolonged exposure to humidity, direct heat, and sunlight accelerates natural leather ageing. A shell cordovan strap, thanks to its density and natural oil content, exhibits superior longevity, often reaching 7–10 years. Regular maintenance—cleaning with a damp cloth and occasional treatment with purpose-made creams—significantly extends service life.
