One of only 500 pieces being made in a limited run back in 2001, this Jaeger Reverso Perpetual Retrograde Calendar watch is my newest toy. To date, it is still Jaeger's only Perpetual Calendar Reverso. On one side, the Day, Month, Retrograde Date and Moonphase are displayed. When flipped to the other side, the time, day/night indicator, and leap year indicator are viewed. The silver dials are guillouche'd on both sides, and I'll upload some macro shots later. The 276 piece manual wind movement is in-house caliber 855 with 39 jewels. The case dimentions are 42mm long, 26mm wide, and 11mm thick. I'm really liking this Reverso. Enjoy!
