The Caliber 801 was introduced in 2007 as RGM’s first in-house movement. Now, after more than a year in development, RGM introduces a classic skeleton version of its most famous movement. A solid gold plaque at the bottom of the dial divides the minute into thirds. The three arm second hand enables a clear view of the movement and the escapement. The different lengths of the arms of the second hand allow for easy reading of the seconds as they pass.
