Ball Engineer Master Ii Aviator Dual Time GM2086C Calibre ETA 2892 A2

Low amplitude with module attached

Very healthy amplitude without module attached means the module is the problem

The wheel is hard to turn on its post which is the cause of the low amplitude and the watch loosing time

Post refitted into the plate

A smoothing broach was used to clean the rust from the inside of the wheel

The post had to be pushed out of the plate and the wheel to release it. It was rusty which is why the wheel was struggling to turn.
