Clone 7750 has a few extra parts

[AP1875]

I wanted to follow Lawsons excellent guide on serving a 7750 however my clone has a few parts not shown in the guide. The bottom can be removed easily can anyone let me know how to remove the other two?

Can anyone help me? I can pick up the bottom wheel easily with my tweezers. I’ve tried the top two and from previous issues with other movements, I’ve learnt if it feels like I need to force it I’m probably doing it incorrectly

Can you get a clearer pic and indicate exactly the problem wheels? The three clearly present don't look installed there, like just set on the movement randomly. I work on 7750s all the time and can't figure out the issue.

Hi Nick, I can take some better pictures tomorrow.
You’re correct I want to remove the three wheels covering the date disc. The wheel next to date number 27 picks up easily, the other two wheels at 23 and 17 seem to be seated fairly tightly.

This plate was on top is that the same as an eta 7750?




I believe ther’re extra gears to facilitate seconds at 9 position

The plate in the background of the last picture then covers the movement ready for dial backplate and dial

This is a 7750 converted to run the seconds hand at 12 for a replica AP ROO. They’re just pressed onto pinions. You need long levers or presto #3 to pull them off.
