	Specific landmark prices on the 16520 itself sit below the headline manual-wind numbers. The Antiquorum 2008 Sport Watch sale lot featured in Hodinkee Part 1 sold at USD 31,200. A 16520 4-Liner fetched USD 43,750 and a 16520 Patrizzi USD 31,250 in the Fortuna Auction 2018 sale. These are catalogue results, not the ceiling. Porcelain MK1 examples have surfaced at higher figures in private treaty and at the major Geneva and New York rounds since.

MK1 is the Floating Cosmograph porcelain dial, R-serial production from 1988. It remains the reference point for first-year 16520 collecting; the watch as a whole gets complicated, the first-year hierarchy does not.

	The MK2 Floating 4-Liner ran on L-serial production through 1989 and into 1990. The OFFICIALLY CERTIFIED line is missing, leaving four lines of dial text where later dials carry five — the source of the collector name. Singer made the dial; the inverted 6 carries over. Surviving examples pair the 4-Liner dial with the early bezel that reads "UNITS PER HOUR" at 9 o'clock and graduates 50–200, a carry-over from the manual-wind 6265 era. Davide Garbati's photography of the Cattin Collection (~~& Sons,~~ 2020) captures the rare bezel-dial combination.		The MK2 Floating 4-Liner ran on L-serial production through 1989 and into 1990.

	The MK3 generation restores OFFICIALLY CERTIFIED on an Inverted 6 dial, running on E through C serials from 1990 through 1992. The dial moves to Rolex production, the OFFICIALLY CERTIFIED line returns, and all five lines space evenly. The inverted "6" in the hour totaliser carries through with four hash marks per five-minute subsection. The bezel transitions inside the MK3 window from the early 50–200 scale with "UNITS PER HOUR" at 3 o'clock to the 60–400 scale with the legend at 1 o'clock; Povey documents three distinct bezel marks across that range.
