Can't get the movement out of my new 116900 air king, movement and movement ring are stuck very tightly in case, is there a trick to this?

The only way is to remove the ring using a tweezer or fine screwdriver, pushing it out from under the groove which allows stem go into the movement

I have tried and bent screwdrivers doing so. It's not moving for anybody this thing.

Think I will wait and let my watchsmith tackle this.

Reps have come a long way but the movements are still such poor quality components. The quality of metal and the finish is nowhere near even close to Swiss, and do buy these rep 31xx your spending genuine ETA money

I don’t know why it doesn’t come out.. I disassembled tons of these and never happened... could it be glued somewhere? Maybe if you turn it dial up and try to make the case gently hit a plastic surface Like a table it can came out.

Just going to leave it, wanted to inspect dial and hands etc and fit auto works but gen autoworks didn't fit anyway so will have to wait until my watch guy starts building the gen movement for me before I fit it, lost 5 minutes between last night and this morning so I'm not thrilled with performance of the rep movement.

Those reversing wheels look like they’re the SA version. (The hybrid between eta and 3130 clone) that doesn’t take any gen parts.

Something is def wrong though. From that I can tell in the picture, that entire assembly should just pop right out. It doesn’t have case screws and the movement tabs are clearly out.

I’m guessing the same. There’s some glue somewhere holding something in place.

Yea... there’s a balance cock under the fake balance bridge. If you paid for the SH3135 clone, I would ask for a refund.

That plus, the beat error tab and the regulator tabs look like they’re sitting in the opposite positions. Probably the reason for a 5min difference in 24hrs

It’s an sa3135, normal regulation tabs, and no fake bridge !! That’s not an a3135 (eta clone + fake bridges)
