The Poljot caliber 9011 PI is a handwound mechanical movement with modifications to display the time with a Regulator style layout. This movement is basically a China-made ETA 6497 clone known as the Hangzhou caliber 9011. The “PI” stands for Poljot International.

Note that although Poljot lists this caliber as having 18 jewels, the stock photos of their Regualator models state “17 JEWELS” on the dials. The original HZ9011 has 17 jewels. Poljot does not appear to provide any images of the caseback or movement in their product listings, however, there is a video (see below), which is the source of the image above.
