The Rolex Explorer II reference 216570 holds a special place in the hearts of many watch enthusiasts. Its rugged design, robust functionality, and enduring legacy make it a highly sought-after timepiece. However, for those venturing into the world of watchmaking modifications or repairs, a crucial component often requiring attention is the case tube. This article will delve into the specifics of the Rolex 216570 case tube, focusing on movement fitting and compatibility, particularly in relation to the common 2836-based movements often used in replica or modified watches. We will also explore the broader context of the 216570, encompassing its price, reviews, and comparison to its successor, the 226570.
Understanding the Rolex 216570 Case Tube and Movement Compatibility
The case tube is a vital part of the watch case, acting as a conduit for the crown and stem. It connects the crown to the movement, allowing for winding and time setting. The precise dimensions of the case tube are critical for proper functionality and a secure fit. In the case of the Rolex 216570, the original movement is the caliber 3186, a highly reliable and robust movement known for its accuracy and performance. However, the cost and availability of genuine 3186 movements often lead watchmakers to explore alternative options.
Mike (Misikpied), a respected figure within the watch modification community, has highlighted the compatibility of the 216570 case tube with movements based on the ETA 2836. He notes that both the genuine Rolex caliber 3186 and converted Yuki movements (often based on the 2836) possess a similar stem height. This similarity is crucial because the stem height directly dictates the depth and length requirements of the case tube. If the stem height is incorrect, the crown may not engage properly with the movement, leading to malfunction.
This information is significant for several reasons. Firstly, it opens up possibilities for cost-effective repairs or modifications. Using a readily available and relatively inexpensive 2836-based movement, coupled with the original 216570 case tube, can provide a functional alternative to using a genuine 3186. Secondly, it highlights the importance of precise measurements and careful selection of components during any repair or modification process. A slight discrepancy in stem height can render the entire assembly non-functional. Finally, it emphasizes the skill and knowledge required to successfully undertake such modifications. Improper installation can damage the case tube, the movement, or both.
Rolex Explorer II 216570 Price and Market Value
The Rolex Explorer II 216570, discontinued several years ago, commands a significant price in the pre-owned market. Its price varies depending on condition, box and papers availability, and overall market demand. Generally, expect to pay a premium compared to other sport models in the Rolex lineup. The factors influencing price include:
* Condition: An excellent condition watch with minimal wear will fetch a higher price than a watch with significant scratches, dents, or signs of previous repairs.
* Box and Papers: The original box and papers (certificate of authenticity) significantly increase the value and desirability of the watch.
