Experience the craft of Arnold & Son in the Royal Collection (ref. 1H6AS.O01A.C79F), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in stainless steel and measuring 47 mm in diameter, defined by a round silhouette. The caseback is open, and the crystal is sapphire, delivering water resistance to 5000 meters. At a glance, the dial balances texture and clarity: a skeleton tone, framed by stick / dot hour markers. At its heart beats a proven engine: the A1766 EOT caliber. With considered ergonomics, it feels composed during extended wear. Brushed and polished elements play with light to emphasize crisp geometry. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
