UNITAS / ETA 6498

[HSL]

The other day I was flipping through some auction sites and stumbled across an offer to buy a Moeris pocket watch movement for about €19 (22$). Took a look at it and thought it would be a shame not to bid on it.

The UNITAS 6498 is a quite nice movement and been cloned by many Chinese companies. Later on it became named ETA 6498.

Most people start their practice career working on a ETA 6497 clone which is a cousin to this movement, they are slightly different in the layout.
So here is a PDF as a small introduction to the UNITAS / ETA 6498 which shows my standard service approach to a movement like this and a small tutorial in how it ends up in a Chinese watch case. 
The PDF is optimized for use online to save server space.

And here are some example shots from my service notes.

A bargain and a great result. Well worth the effort. Many thanks for putting the tutorial together.

Thank you, but I already have the ETA tech sheets.
My Tutorial only shows an alternative and a more detaild way to service this movement with some tips and tricks.
One more tip I can share i were to find all the latest tech sheets.
This is for the ETA/UNITAS 6498.
