Can’t find anything on the web that looks like this..
seems a lot of effort to build a copy watch if it is one
Any ideas ?

Any photographs of the dial and case sides?

 

Standard ETA quartz chrono (251.264 etc).

Looks legit so far.

Need more info though.

 

Not a copy, just a modern Certina DS from the last few decades.

Googling the model number gets you other photos of the same model.
