Rolex Zenith Cosmograph Daytona Chronograph ref. 16523 from 1999 A-serial The Zenith component refers to the 4030 calibre movement but the details are all in the dial. An easy way to spot this is the running seconds hand at the 9 sub dial and the thinner hour marker. The last part, once seen cannot be unseen on other newer Daytonas. On this zenith Daytona, notice how the horizontal lines on the 9 o’clock sub-dial line up with the 9 marker. One the Rolex in-house movement it floats above. While this era of Rolex is not considered vintage yet, it is a future icon.
