The Rolex Explorer II 16570, particularly the reference sporting the in-house calibre 3186 movement, represents a fascinating chapter in Rolex's history. It stands as a bridge between generations, a transitional model that seamlessly blends the aesthetic appeal of older designs with the technological advancements of the new millennium. This article will delve deep into the specifics of this compelling timepiece, exploring its dimensions, price, availability, and comparing it to its successor, the 216570. We will also conduct a thorough review of its performance and overall desirability within the collector's market.
Rolex 16570 Dimensions and Size:
The Rolex 16570 boasts a robust yet wearable presence on the wrist. Its dimensions are carefully considered, striking a balance between functionality and elegance. The case diameter typically measures 40mm, a size that has proven consistently popular over the years. This makes it suitable for a wide range of wrist sizes, appealing to both men and women with larger wrists. The lug-to-lug measurement, while not always explicitly stated, generally falls within the 47-48mm range, further contributing to its comfortable fit. The thickness of the watch, typically around 12mm, is a testament to the robust construction and the inclusion of the self-winding 3186 movement. The relatively short lug-to-lug measurement, compared to some modern sports watches, makes it surprisingly comfortable even for those with smaller wrists. This is a key factor in its enduring appeal. The overall proportions of the 16570 contribute significantly to its balanced and classic aesthetic, a hallmark of Rolex design philosophy. The slightly thicker case compared to its predecessor reflects the incorporation of the improved movement.
Rolex 16570 Movement: The Heart of the Matter
The most significant feature distinguishing certain 16570 references is the inclusion of the calibre 3186 movement. This represents a pivotal moment in Rolex's history, marking a shift towards fully in-house movements with enhanced performance and reliability. Prior to the 3186, the 16570 utilized the ETA 2892-A2 movement, a reliable workhorse but not entirely manufactured by Rolex. The introduction of the 3186 signified Rolex's commitment to complete vertical integration, ensuring superior quality control and a unique identity for its timepieces.
The 3186 is a self-winding mechanical movement with a power reserve of approximately 48 hours. It's known for its accuracy, robustness, and resistance to shocks and magnetic fields. Its improved efficiency and reliability compared to the ETA 2892-A2 made it a significant upgrade, enhancing the overall longevity and performance of the 16570. This movement is a testament to Rolex's dedication to precision engineering and its constant pursuit of improvement. The transition to the 3186 represents a key evolution in the 16570's lineage, setting the stage for future generations of Explorer II models. Collectors often prioritize the 3186-equipped 16570s for their improved performance and the significance of the movement within Rolex's history.
