The Rolex Explorer II reference 16570 holds a special place in the hearts of many watch enthusiasts. Its rugged design, robust functionality, and association with exploration make it a highly sought-after timepiece. However, within the 16570 lineage lies a subtle yet significant variation: the movement. This article will delve into the differences between the Rolex caliber 3185 and the caliber 3186, focusing specifically on their implementation in the Rolex Explorer II 16570, examining their impact on value, availability, and overall desirability.
Rolex Explorer 16570 vs. 3186: The Significance of the Rehaut
The most immediate distinction between 16570 models equipped with the 3185 and 3186 movements lies in the presence of a rehaut. The rehaut, a small ring or groove on the inside of the crystal, is a subtle detail often overlooked by the untrained eye. However, its presence or absence is a key identifier for discerning collectors. The Rolex Explorer II 16570 models fitted with the caliber 3186 movement feature this rehaut, a detail that enhances the watch's overall aesthetic appeal and contributes significantly to its collectibility.
The inclusion of the rehaut on the 16570 with the 3186 movement is not merely cosmetic. It represents a shift in Rolex's manufacturing processes and a subtle upgrade in the watch's construction. This refinement, coupled with the improved movement itself (as we will discuss below), makes these specific 16570 models more desirable and, consequently, more expensive.
The absence of the rehaut on the 16570 with the 3185 movement isn't necessarily indicative of inferior quality. Instead, it reflects a different stage in Rolex's production methods and design philosophy. These earlier models, while still highly regarded, lack the subtle refinement of the later rehaut-equipped versions. This difference in manufacturing contributes to the varying market values.
Rolex 3185 vs. 3186: A Comparative Analysis of Movements
The heart of the difference between these Explorer II models lies in their movements: the Rolex caliber 3185 and the Rolex caliber 3186. While both are highly reliable and robust automatic movements known for their precision and longevity, several key distinctions exist.
The caliber 3185, the earlier of the two, is a workhorse movement that served Rolex faithfully for many years. It's a proven design, known for its durability and accuracy. Its robust construction ensured that it could withstand the rigors of daily wear, making it a suitable movement for the adventurous spirit of the Explorer II. However, the 3185 lacked some of the refinements introduced in the later 3186.
The caliber 3186, introduced later, represents an evolution in Rolex's movement technology. While maintaining the reliability of its predecessor, the 3186 incorporated several enhancements, leading to improved performance and longevity. These improvements might be subtle, but they contribute to the overall superior quality and desirability of the 16570 models fitted with this movement. While specific details regarding internal differences are often kept proprietary by Rolex, the improved performance and the addition of the rehaut on the case suggest a more refined manufacturing process.
