Rolex Explorer II

Description

In the mid 1980s, Rolex updated its Explorer II and introduced the ref. 16550. In a departure from the 1655, this five-digit predecessor is distinctive with a sapphire crystal, and glossy dial. Only offered by the brand for around four years, the ref. 16550 is one of the least commonly seen watches from Rolex in the 1980s era. The Explorer II Reference 16550 succeeded the original Explorer II Reference 1655 Freccione, so named for its wide, bright orange 24-hour hand. The updated Reference 16550 was equipped with Rolex’s new caliber 3085, a serious upgrade from the Reference 1655: it featured a quick-set date, hacking seconds, a 42-hour power reserve, and perhaps most importantly, independent adjustment of the GMT hand, allowing the wearer to actually track multiple time zones. Along with the earlier released GMT-Master II (itself a new model), this means the Reference 16550 was the first Rolex to offer an independently adjustable GMT hand—a true innovation from a brand that has made its name developing useful tools for pilots and other professionals.
