Are you sure of the Calibre?
There were several iterations of the 34x and 35x (34X being sub seconds, and 35x being center seconds), most of which were not chronometers. I am guessing because of the generic crown the watch did not come with paperwork from a recent Omega service.
How is the timekeeping?
If you could post pictures of the movement the would be helpful.
That piece probably needs a factory service. You will get the correct crown and one of the most accurate watches you will ever own when it is finished.
I have an almost identical piece in 18k RG and athe cal 354. Same dial configurations except the subdial.
