Strap for Hornet World Timer Skeleton

The lug width of the Arnold & Son Royal Collection 1H6AS.O01A.C79F is 20mm. This measurement represents the linear distance between the spring bars that attach the strap to the watch lugs. Measuring this distance correctly is essential to ensure compatibility with aftermarket straps.

The optimal strap depends on intended use and aesthetic preference. For formal wear, a superior-grade alligator or vegetable-tanned calf leather enhances the luxurious nature of the steel case. For daily versatility, a 20mm NATO provides practicality whilst maintaining gravitas. For dynamic environments, FKM rubber ensures resilience and comfort.

To replace the strap, use a spring bar removal tool. Position the tool gently beneath the spring bar securing the strap to the lug, apply slight pressure inward to compress the spring, then extract the bar. Repeat on the second bar. Insert the new 20mm strap by aligning the hole with the spring bar and pressing until you hear the spring engage.

Yes, any strap with a 20mm lug width is compatible with the 1H6AS.O01A.C79F. Compatibility depends solely on lug width, not on the watch brand or model. Milano Straps offers a curated selection of 20mm straps in premium materials—alligator, shell cordovan, vegetable-tanned calf, NATO, and rubber—suitable for this case.

The lifespan of a leather strap varies according to material quality and usage patterns. A superior-grade alligator or calf leather, worn moderately, typically lasts 3 to 5 years before requiring replacement for aesthetic reasons. With proper care—avoiding prolonged water exposure and maintaining dryness—longevity increases significantly. Shell cordovan, if well-maintained, can exceed 10 years, developing an increasingly sought-after patina.
