Identifying a Helvetia auto

I was recently given what was left of my grandfather's watch collection and this one stumped me. Decided to stop lurking and make my first post. I searched this forum and Google but can't find anything too close to this watch except for some bizzare mentions about the movement on a Romanian site.

My grandfather was from Romania, and I'm guessing the movement was specific to the area because the date calendar is in French/Romanian.

It's a Helvetia automatic, and there's not many clues to wether is authentic or its period. It has to be relatively recent as it has an ETA 2878. What the 0004.50 means on the caseback is beyond me. The caseback was loose...

The watch itself doesn't currently work. It winds and holds power, but doesn't run. I'm looking to get it repaired, but I'd like to know what I'm looking at first.

Sorry if the pictures are upside down. For whatever reason the orientation when I upped them to the post isn't the same as what they are on my computer. o|

So, any thoughts?
