FAQ
What is the lug width of the Arnold & Son Royal Collection 1LCAP.S07A.C111A?
The lug width is exactly 20 millimetres. This measurement represents the internal distance between the two lugs on the case and is essential for sourcing compatible straps. To verify this accurately, remove the original strap and measure with a digital calliper, positioning the points within the terminal holes of the lugs.
Which strap type pairs best with the Royal Collection 1LCAP.S07A.C111A?
Alligator remains the classical choice for this rose gold 40mm case: its uniform grain evolves naturally over time in harmony with the case's patina. Alternatively, vegetable-tanned leather offers a more pronounced texture and colourways that age from tobacco to cognac. For dynamic contexts, high-density polyamide NATO straps provide functionality with understated elegance.
How do I change the strap on this timepiece?
Remove the original strap using a spring bar tool. Insert the small lever into the hole on the spring bar, lift gently to release tension, and slide the strap downward. To install the replacement strap, align the strap lug with the spring bar, insert the spring bar into the terminal holes, and ensure it is secured on both sides. Always verify correct seating before wearing.
Are aftermarket straps compatible with the 1LCAP.S07A.C111A?
Yes, any strap with a 20-millimetre lug width is fully compatible. Our range of 20mm straps encompasses options in alligator, leather, vegetable-tanned leather, NATO and structured rubber, all designed for standard spring bar installation. Always verify the strap is designated for the correct lug width prior to purchase.
What is the typical lifespan of a leather strap on a frequently worn watch?
The durability of a leather strap depends on intensity of use and exposure to moisture and perspiration. Under normal daily-wear conditions, a quality alligator or leather strap typically functions for four to seven years before replacement becomes necessary. Alligator resists wear better than more delicate leathers; vegetable-tanned leather develops visible patina but remains functionally superior longer. Prolonged exposure to perspiration and humidity significantly reduces lifespan. Proper maintenance—periodic cleaning and natural drying—substantially extends strap longevity.
