A client has sent in his Rolex. It belonged to his father and means a lot to him. Two years ago it was serviced by a jeweller in Cardiff, but kept terrible time. Contacting them he got no willingness to inspect the problem. He dropped the watch and it has stopped.
The movement looks fairly clean at first glance.
Well the shock protection spring has opened hence stopping the movement.
I correct the shock spring, but watch is not preforming like a Rolex should!
On closer inspection, there is a lot of dirt in the jewel holes and micro fibres in the gear train.
I take apart the auto winder mechanism.
Wonderful blue dial!
I take apart the setting/winding mechanism.
Here you can see the Rolex calibre 3000 gear train layout.
Movement has been cleaned and ready to be put back together.
i fit a new mainspring.
I see that the balance moves freely after fitting the shock jewels.
Gear train coming back in place.
Base movement almost back together.
Base movement back together and ticking.
The watch definitely needed another service! It’s now running like a Rolex should.
Movement ready for the dial.
Dial and hands back in place.
Movement goes back into the case.
I fit the osculating weight.
I doubt the movement was actually taken apart in the last service. It’s highly unlikely that amount of dirt could accumulated around the pivots in 2 years. In any case the watch looks and preforms great again.
