Service Certina Automatic DS (pre turtle back). Calibre: 25-45
I got a nice Certina DS pre turtle back calibre 25-45. These where only made in 1959 and 1960. Later models had the famous turtle back logo. The watch was not running and I could hear the oscillating weight rattling in the case.
Pre turtle case back.
Rotor was loose so I have taken it out. Hmm broken off case screw and missing case clamp.
Noooo…. Someone managed to screw in the wrong case screw far enough to dent the dial and then break it off.
Very funky hands.
At least the case screw is easy to remove when it’s sticking out like that…
No wonder this watch was not running, there are large fibres wrapped around the upper pivot.
I remove the auto winder bridge.
Movement coming apart.
Here you can see the train layout.
Movement has been cleaned and is ready to be put back together.
I fit a new mainspring in the clean barrel.
The movement coming together again.
The winding/setting mechanism back in place. I’m fitting a new stem as the old one was rusty.
Movement back together and ticking.
Preforming very well.
Movement ready for the dial and hands.
Movement goes back into the case.
I fit the oscillating weight and the watch is back together.
Great looking watch put back together the way it should be.
