For those that don't have Instagram:
The account is a long time Seiko modder that uses cases and Seiko/Miyota movements to create replicas (not using "real" logos).
In the video he's using a Dremel tool to literally "Pop" the watch movement out of the case to start testing putting it into one of the steel RO Chinese cases he uses for the Seiko kits he makes and sells.
It won't be long, and these do have the logs on the dials...
