Next we have the Master Ultra Thin Perpetual Enamel. This watch is powered by an updated version of the JLC 868 movement, the JLC 868A/2. If you compare this watch to the previous generation of the Master Ultra Thin Perpetual, which comes with the 868/1 movement, you can see that most of the indications appear to have rotated 180 degrees. The moon phase is now at the bottom of the dial, and a hand has been added to the moon phase so that the position of the moon can be read in either hemisphere. Moreover, the year is now read via two windows inside a sub-dial that shows the months. The older edition indicated the years in a single window between seven and eight o'clock. I think that while both look great, the newer version wins points for being more symmetrical. Like the older version, this new one comes in a comfortable 39mm case, though the thickness has increased slightly from 9.2mm to 10.44mm. Of course, the new watch benefits from a more complex enamel dial, and I think the minor increase is acceptable given what you get in terms of the beauty of the dial. The watch also sees a near doubling of the power reserve from about 38 hours to 70 hours. The Master Ultra Thin Perpetual Enamel is limited to 100 pieces.
