Pretty sure what you actually have is a Calibre 185 movement, which is a combination of an ESA 555.232 base quartz module (i.e. time only) with a mechanical dubois-depraz chronograph module. The ETA equivalent to your base module is ETA 955.232

 

Assuming that it's the base movement that needs repair (rather than the chronograph), then take a look at this one:

Beware- it will need a watchmaker to remove the chrono module from your existing module and fit to the new base movement

 

Yes..this one is being sold for just the circuit
