This stylish Certina is not running and I suspect it has a broken mainspring.
Movement does not look too bad.
Here you can se the winding/setting mechanism.
Train bridge removed and you can see the gear train.
As expected a broken mainspring.
All the parts clean and ready to go back together.
New mainspring fitted.
I see that the balance moves freely.
Movement comes together without any problems.
Setting/winding mechanism back in place ready for the dial.
Movement looking very good.
Watch is preforming okay, but I was expecting better.
I found that the mainspring I ordered from our supplier is thinner than originally specified, so I order a NOS mainspring on E-bay.
The upper barrel arbor hole was borderline worn so I decided to make and fit a new bush.
I feel much better about the watch now that it has the correct mainspring and I have repaired the upper barrel arbor hole with a new bush:)
That is more what I was expecting from this watch;)
Very nice dial on this watch! I also replaced the crumbling old luminous compound.
Real mid 60’s classic.
I’m so jealous of the lighting in Christian’s and your shop. There seems to be not a bit of yellow light in there. I imagine most of that can be attributed to north facing windows. Any other secrets? Maybe like the type of overhead or bench lights?
LED overhead lamps and daylight from the windows;)
