This precision pendulum clock made by Riefler in Nesselwang is designated as type A³, a standard that was used almost unchanged from 1913 to 1965, when the production was eventually discontinued. According to the sales books, the clock was delivered without pendulum but was then fitted with an original Riefler pendulum type "J"; the clock is also excellently equipped with mechanical adjustment system through small extra weights and aneroid compensator.
The clock is in magnificent condition, which is obviously partly due to the fact that the Riefler clocks were produced fairly recently. Movement and dial are as good as new, the case is almost immaculate and of course the aneroid in different metal colours is always an eyecatcher. This is a fantastic treasure for all lovers of precision pendulum clocks who appreciate the outstanding Riefler technology even when it comes without a long history of observatory service.
