The "Hermle masterpiece". The futuristic, elegant case with duo-tone finish has crystal glass on all sides, so you can have a direct view on the complicated Westminster bell strike movement with automatic night shut-off and 11 jewels escapement. Another highlight is the special designed dial in anthracite. The newly developed technique of the eternal calendar tells you precisely the day of the month, the day of the week, the month as well as the leap year. You therefore do not have to change the date every second month. This brilliant technique is functioning up to the year 2100. Only then, you will have to reset the calendar, because February 29 does not exist during this year.
