It's the combination of the calendar complication and the waterproof Oyster case that makes the 6062
link such a beautiful contradiction. While the 8171 had a larger snap-back case the 6062 has a case similar to that
link found in your everyday Datejust Explorer or Day-Date. That
link Rolex even thought to put a calendar paired with its "perpetual" automatic winding system inside its innovative new Oyster case is mind-blowing.
