May just require cleaning and lubrication
There's no way to guess what parts may be required without taking it apart and examining it, but sometimes a loss of amplitude and accuracy just indicates that the lubricants have exceeded their useful lifespan. A qualified watchmaker should be able to get it back to COSC specs.

Amplitude problem
Hi This is about one of my favorite watch Mido Commander Chronometre with ETA2837. I have experience the low amplitude problem around 250++ along with 7-8 seconds slow per day(dial up). I would like to have overhaul to bring back its Chrometre grade but I...

Mido Commander
The Mido Commander is one of my favorite watches too. Unfortunately mine is not a chronometer. It sounds to me like, as John said above, your watch probably needs cleaning. After several years the oil in the bearings looses its lubrication properties. The...
I agree, with John and Don...
Hello ste, The only thing I can add is, I believe this is a one piece case. During service, you should consider replacing the crystal and crown. Small fractures often form around the lip of plastic like crystals. Crowns are replaced for precaution. Mido i...
The watch
Actually I have serviced the watch once. But the timekeeping is just not good as what I expected. By the way I also have no idea if the watchmaker do it on right way. So that's why I feel that changing some parts could make the amplitude better. ...
