The Rolex Explorer II reference 16550 holds a special place in the hearts of many watch enthusiasts. Its robust design, practical functionality, and rich history make it a highly sought-after timepiece, particularly the transitional models like the 1986 example described above – a 40mm stainless steel Oyster case with a white "Polar" dial and accompanying papers, currently listed on Chrono24 for $15,500 + $50 shipping. This article will delve deep into the world of the Rolex Explorer II 16550, exploring its specifications, price points, variations, and what makes it such a desirable collector's item.
Rolex Explorer II 16550 Specs:
The Rolex Explorer II 16550, produced from 1984 to 1989, represents a significant evolution in the Explorer II line. While maintaining the core principles of its predecessors, it introduced refinements and improvements that cemented its position as a rugged and reliable tool watch. Key specifications include:
* Case: 40mm stainless steel Oyster case, renowned for its water resistance and durability. The Oyster case, a hallmark of Rolex design, features a screw-down crown and caseback, ensuring protection against water and dust.
* Movement: Caliber 3085, an automatic self-winding movement, known for its accuracy and reliability. Rolex movements are meticulously crafted and rigorously tested, guaranteeing exceptional performance. The 3085 offers a power reserve of approximately 45 hours.
* Dial: The dial is where the 16550's variations become most apparent. While generally black, white ("Polar") dials, like the example mentioned earlier, are highly coveted. These dials feature luminous hour markers and hands, ensuring excellent legibility in low-light conditions. The signature orange 24-hour hand is a key feature, perfect for navigating in challenging environments or distinguishing between AM and PM in low-light conditions.
* Crystal: A scratch-resistant sapphire crystal protects the dial from damage. Sapphire crystal is highly durable and offers superior protection compared to acrylic crystals used in earlier models.
* Bracelet: Typically fitted with a stainless steel Oyster bracelet, offering both comfort and durability. The Oyster bracelet features solid links and a secure clasp, ensuring a comfortable and secure fit.
* Bezel: The fixed bezel features markings for the 24-hour hand, further enhancing its functionality as a tool watch. While generally unmarked, some collectors seek out examples with subtle wear or markings.
Rolex Explorer II Size Chart:
The 40mm case size of the 16550 is considered a classic size for a men's sports watch. It's large enough to be easily read, yet not overly bulky on the wrist. This size makes it appealing to a wide range of wrist sizes. While a precise size chart isn't readily available from Rolex, the 40mm measurement refers to the diameter of the case excluding the crown. Lug-to-lug measurements will vary slightly depending on the specific model and bracelet. For those considering purchasing a 16550, it's recommended to try it on to ensure a comfortable fit.
