I recently scored this Dugena Monza Ana-Digi:

It was sold as non-working, but the only real problem was that the polarising filter had completely failed. The battery hatch was also missing, but I got that sorted with a hatch from an old Compuchron LED. After a thorough clean of the movement, and a new polarising filter, it now runs sweet:

Build quality is excellent, although setting is a real nightmare. With no crown, the hands must be advanced one minute at a time via the buttons ! For example, if you need to advance 11 hours, it requires 11x60=660 button pushes
The movement is marked EST4330, although it seems identical to the Cal-2045 used in Tissot TS-X models.
I'm starting to really appreciate these 1980s ana-digis.
