I bought it for about three years ago.
The movement is 25 jewels Eberhard cal. 896-8J, it’s a hand wound eight days movement with double barrels and power reserve indicator. It takes about 80 full turns on the crown to wind it up.
The movement is not in-house, but highly modified by Eberhard & Co. The base movement is a Peseux 7001.
