These are good low beat automatics, robust and reliable. They are in new Gavox Legacy, and many older Gigandet, older Invicta

You seem to know movements. I bought an old Sea Dweller 40mm (date just). The previous guy opened it up and messed up the movement, with some of the components also missing. Dealer gave me a quote and I cannot afford the repair. What Miyota or ETA movement can I use as a replacement. The rest of the watch is still in fair condition and I would like to use it.

Why do these watch companies ruin watches by adding ugly plastic shields around the movements? If the case is too big for the movement it probably means something. And if the movement is too small at least make a metal spacer!

Debert Bathyscaphe that I own (Blancpain Fifty-Fathom knockoff) has this movement. This movement is also known for its shutter/stutter second hand sweep movement.

Hey. I bought Zeppelin Lz 127 with this movement. I got it 3 days ago and First day it added 16 minutes and second day 15 minutes. Is it something temporary or will I have to send it back? And on top of that, it changes date in noon? How can I adjust date so it turns in midnight? I didn’t expect this with this brands. Some advices guys?
