If it’s a Certina, it has to be Joris’! Well, not exactly, but it belongs to a friend of his, and there is a long story involving bicycles, watches, and other things… The gist of it is that Joris has to have the watch fixed, and will get a bicycle in exchange.The case has already be pre-cleaned, but there is still a lot of dirt that has to be removed.
The inside looks pretty clean, but the watch runs too fast.
Look at the solidified grease on the winder clutch wheels!
Nice and tidy bottom plate.
Got to love those Certina movements!
It’s been a while since this watch has been serviced.
Solidified grease on the barrel bridge.
The mainspring is pretty dry – time for a new one.
The date changer doesn’t work – let’s see why.
The little spring in the date change wheel is broken, and somebody glued it in with super glue. I can’t get hold of a replacement wheel, and I don’t have wire that fits to make a new one. So for the time being, it will be the first every day, until a replacement can be found.
The bottom plate comes apart.
Everything ready for the cleaning machine.
And I’m ready for reassembly.
As usual, I start off with a new mainspring.
The base movement is back together, and the movement is ticking.
That looks pretty good!
The auto-winder assembly goes in.
And the movement is ready for casing.
I take the bezel ring off to replace the crystal and clean the case.
The dial has some damage, but is looking pretty good considering the age of the watch!
Lovely movement – just the rotor missing.Back together and cased – a great watch!
