I would guess older Japanese probably Miyota. No attempt at decoration or finely cut gears. Them and Seiko use the single screw to hold down the weight. Snap on case back is something the Swiss would avoid also and without the holder that dial swims in there. Chrono or rotary small date/day dials without looking at other side. Dial logo would point in a better direction.
I don't know how confident you feel, but there is a possibility that if you do a service on that movement, there tend to be marks and numbers in some bridges. Or if you take it to the watchmaker who will do the service for you, he will most likely be able to identify it after the service
