The Rolex Explorer II reference 16550, often simply referred to as the "16550," holds a special place in the hearts of watch enthusiasts. This iconic timepiece, produced from 1985 to 1989, represents a transitional period in Rolex's Explorer II line, bridging the gap between the earlier, more utilitarian models and the modern iterations. Its distinct features, including the striking GMT hand and variations in dial color, contribute to its enduring appeal and strong performance in the secondary market. This article will delve into the specifics of the Rolex 16550, exploring its technical specifications, comparing it to its successor, analyzing its current market value, and providing guidance for prospective buyers.
Rolex Explorer 16550 Specs: A Technical Overview
The Rolex 16550 boasts a robust 40mm Oyster case, crafted from stainless steel, providing excellent durability and water resistance. This case houses the caliber 3085 movement, a self-winding mechanical movement known for its reliability and accuracy. This movement is a key differentiator from its predecessor, the reference 1655, which utilized the caliber 1575. The upgrade to the 3085 brought improvements in precision and longevity. The watch features a screw-down crown and caseback, enhancing its water resistance to a respectable depth, typically rated at 100 meters.
One of the most defining characteristics of the 16550 is its independent 24-hour hand, often referred to as the GMT hand. This hand allows the wearer to track a second time zone, a particularly useful feature for travelers. The GMT hand is usually a bright orange, providing excellent contrast against the dial, and adds to the watch's distinctive aesthetic. While the orange GMT hand is the most common, variations exist, adding to the collectibility of certain models.
The dial itself is another point of interest. While black dials are prevalent, the Rolex 16550 is also known for its "cream" or "tropical" dials, which have developed a creamy patina over time due to the aging of the luminous material. These dials are highly sought after by collectors and command premium prices. The hands are typically luminous, ensuring readability in low-light conditions. The crystal is usually made of scratch-resistant sapphire, offering superior protection to the dial.
Rolex 16550 vs 16570: A Generational Shift
The Rolex 16570, the successor to the 16550, marked a significant shift in the Explorer II line. While both share the fundamental design ethos of the Explorer II, several key differences exist. The most noticeable change is the movement. The 16570 utilizes the caliber 3185, a more advanced movement offering improved performance and shock resistance. The 16570 also features a slightly updated case design and often incorporates a different lume material, resulting in a different appearance of the hands and markers over time.
