Service Certina Automatic DS (pre turtle back). Calibre: 25-45

P1120110I 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.

P1120113

Noooo…. Someone managed to screw in the wrong case screw far enough to dent the dial and then break it off.

P1120114

Very funky hands.

P1120115

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.

The winding/setting mechanism back in place. I’m fitting a new stem as the old one was rusty.

Movement back together and ticking.

P1120231

Preforming very well.

P1120233

Movement ready for the dial and hands.

P1120297

Movement goes back into the case. 

P1120300

I fit the oscillating weight and the watch is back together.

Great looking watch put back together the way it should be.
