Arnold & Son
Royal Collection 1LCAP.S06A.C111A— lug 20mm

The lug width is 20mm, the usable space between the case lugs where the watch strap is fitted. This dimension is specific to the model and determines compatibility with aftermarket straps. To verify correct measurement, place a ruler perpendicular to the case between the two spring bars.

An alligator strap with vegetable tanning or shell cordovan amplifies the formal register of the rose gold case and neoclassical aesthetic. For dynamic contexts, a cotton-linen NATO or vulcanised rubber maintains elegance without compromise. Choice depends on use: formal, daily wear, or sports.

Use a dedicated spring bar tool to gently compress the pins positioned at the case lugs. Do not use sharp objects that could scratch the rose gold. Remove the old strap, then insert the new one, ensuring the spring bars click into their new positions. Verify the strap is perfectly aligned before wearing.

Yes, provided they respect the 20mm lug width and are constructed with quality materials (vegetable-tanned leather, alligator, vulcanised rubber). Artisanal aftermarket straps often offer superior finishing compared to OEM options and allow aesthetic personalisation coherent with your style.

Duration depends on intensive use and environment: 12 to 36 months with standard maintenance. A shell cordovan strap resists longer (36-48 months) due to fibre density. Humidity, heat, and frequency of use accelerate wear. Rotating between multiple straps extends each one's lifespan and allows leather to absorb ambient humidity naturally.
