Description

The large Baumgartner caliber 670 is a rather uncommon pin lever movement. It has got a clutch winding and setting mechanism (very good for service works) and uses a balance, that has got a long regulator arm and a deck jewel. The anchor block allows precise justage, which is helpful on such a high movement.

As usual on Baumgartner movement, on the dial side, the minute wheel and the hour wheel are driven indirectly and are located on the dial side only. The neccessiary friction clutch sits on the mainspring barrel and can be adjusted by a very large hands setting wheel.

According to the Flume K3, this movement, which also has got an integrated indirect center second hand, uses a very unusual beat rate of 17280 beats per hour (4.8 Hertz). Normally, 5 Hz (18000 A/h) are used.
