The caliber 801 skeleton has been in development for more than a year, and the hard work resulted in a fresh take on the 801 movement that allows us to easily admire its architecture. When skeletonizing a movement it is easy to go too far and end up with a watch that is difficult to read, or is very fragile due to the amount of metal removed from the mainplate and bridges. In my opinion, RGM got it just right with the 801 skeleton. In a way, it is is the logical progression of the 801 series.
