A customer has sent in his Patek Philippe calibre 30-300 PM for a service.
Movement does not look especially dirty, but there are some fibres here and there.
Dial and hands before I remove them.
I notice there is a little more dirt on the dial side.
I now start taking apart the gear train.
Here you can see some of the gear train exposed.
I will take out the mainspring and clean it.
Movement cleaned and ready to be put back together.
Mainspring is oiled and put back into the barrel.
I see that the balance moves freely after fitting the shock jewels.
The ratchet wheel is placed on the underside of the barrel bridge.
I fit the barrel and barrel bridge.
I now fit the setting/winding mechanism.
The gear train goes back into the movement.
I’m happy to have a ticking movement again! I must say it does look very nice.
That’s good enough for an old Patek;)
Ready for dial and hands.
Dial and hands back in place
Movement goes back into the case.
