Perpetual calendar watch with world time, has four motors and runs in (I believe) seventeen jewels. It runs with just one 1.5v silver-oxide battery which is remarkable because of how much power one of these would normally draw.
I have sold the watch one month ago for 550 Euro, the original price in 1991 was approximately $400.
