The Rolex Explorer II reference 16570, particularly the coveted white dial variant, is a watch that rewards meticulous observation. While seemingly simple at first glance, a close examination reveals subtle nuances in its design and construction that speak volumes about Rolex's commitment to precision and enduring quality. This article will delve into a detailed close-up analysis of the 16570 white dial, focusing specifically on the often-overlooked asymmetries present, particularly concerning the crown side and the differences between the crown-side and 9 o'clock side lugs. We will also briefly touch upon the broader context of the 16570 within the lineage of Rolex Explorer models, including a comparison to its predecessor, the reference 16550.
The Crown Side Conundrum: A Matter of Millimeters
One of the most fascinating aspects of the 16570, often only apparent upon close inspection, is the subtle difference in the case construction between the crown side and the opposite side. While many might assume perfect symmetry, a careful examination reveals that the case flanks, particularly around the crown, exhibit a minute yet discernible asymmetry. The crown itself, of course, protrudes, but the area immediately surrounding it displays a slightly different profile compared to the 9 o'clock side.
The key observation lies in the relationship between the case and the bezel insert. While the bezel sits flush against the case on both sides, the crown side shows a slightly more pronounced integration. This is not a significant deviation; we're talking about fractions of a millimeter. However, this subtle difference affects the overall perceived shape of the case. The effect is subtle, almost imperceptible to the untrained eye, but it contributes to the watch's unique character and is a testament to the precise manufacturing techniques employed by Rolex.
Furthermore, the placement of the crown itself warrants detailed analysis. While the crown guards effectively protect the crown, the crown should still be subtly recessed within the case band. This isn't always immediately apparent, especially in photographs, but a close examination with the watch in hand reveals a slight indentation around the crown, ensuring it doesn't protrude excessively. This carefully considered design element not only enhances the watch's ergonomics but also contributes to its overall aesthetic balance. Any significant deviation from this carefully engineered recess could indicate a potential issue with the case construction or a possible aftermarket replacement.
The lugs themselves, as mentioned earlier, exhibit a subtle difference in shape between the crown side and the 9 o'clock side. The crown side lugs often appear slightly more curved or rounded, while those on the 9 o'clock side might seem marginally straighter or more sharply defined. This difference, again, is extremely subtle and might be attributed to the manufacturing process, the slight pressure exerted during assembly, or even the inherent variability in the machining of the case. However, the consistency of this asymmetry across various examples of the 16570 suggests that it is a deliberate, albeit unintentional, characteristic of the design.
