Can anyone help a novice in distress,I have a 1952 Omega cal.420 in need of repair but being a complete beginner in this field i don't even know what the part needed is called or the part number!! Can anybody come to my aid,The part in question is the wheel/cog highlighted in the photograph,Any assistance would be greatly appreciated
Welcome! I'm not sure, but one of the experts will chime in soon (cross fingers). Can we see a pic if the watch it comes from - no pic, no help!
I posted a pic of the movement do you need the full watch? And many thanks for putting me on the right track.
You have to remember your dealing with an amoeba when you talk to me!! All i can say is the wheel in question is not centre.
I beleive it's the winding wheel or compensating balance wheel in question...all movements are assembled differently although the parts are similar.....still gathering, and learning along with yah....soon an expert will pop by rest assured.
I believe you are looking for the sweep seconds/third wheel on the this movement, though I am not very familiar with 420s . You should be be able to get one cheap here, http://www.julesborel.com or in your case being in the UK , Cousins maybe be a better alternative.
It's an intermediate wheel which indirectly drives the sweep second hand. What it's actually called by a parts store is another story. It's a separate wheel than any in the train. A watch with subseconds has the second hand driven directly by the fourth wheel. Center sweep was done a few different ways back then. Normally, I'd link you to a schematic from this site: http://www.omega-fanatic.com/pages/omega-movement.php But the 420 is not listed.
Thank you,I am making a little more progress with every post,At the start of this i did'nt even know what to call it.
