A client has sent in his Zodiac. It badly needs some attention. The first thing I notice is that the bezel does not turn and that the rotor is clanking against the case back.
Movement looks decent.
The rotor post is broken. Hence why the rotor is clanking around
Here you can see where the rotor post is broken.
These Zodiacs have a funky micro regulator.
Dial is in very good condition!
I remove the hands and dial.
I start taking the date mechanism apart.
I now start taking the setting/winding mechanism apart.
Movement almost taken apart.
Here you can see the gear train layout. Nice hacking lever construction.
The dreaded 2nd wheel with the clutch pinion. I used to hate taking these apart because if they brake, there are not too many spares left out there…
Using the Platax tool I can rest the clutch pinion on the Collet remover and safely press out the 2nd wheel arbour.
The barrel is actually riveted shut..
And leaving it closed is no option… Look how dirty it is!
Dirty!! No wonder the Bezel does not turn..
Movement cleaned and ready to be put back together.
Mainspring cleaned and back in the barrel, you can see the carnage from opening it… If you have a better suggestion please let me know!:)
I see that the balance moves freely after fitting the shock protection jewels.
Clutch is oiled and pressed back onto the 2nd wheel.
Gear train back together looking good! I like the jewelled barrel bushes.
Date and winding/setting mechanism back in place.
Dial and hands back on the movement.
Movement goes back into the case.
I fit the autowinder gears and bridge. Now with a new rotor post!
Now the rotor works perfectly.
Very good performance.
Now that looks a lot better than before!
