Like London busses – this the the 2nd out of 3 Rolex watches with the 3135 movement in my workshop this month. That’s the power of Google – as soon as I do the first one, my ranking for that particular calibre goes up, and so on. Not that I mind; I love the 3135. It’s simply a great movement, and beautifully executed.
This one was sent in by Nici, who must be the dream wife of every watch enthusiast! She arranged everything, and sent in her husband’s watch for a service. That’s got to be love…
The watch hardly moves, and stops regularly, even when fully wound. So something has to be wrong…
As I used to work as a car mechanic, I recognise these marks straight away – they are little pieces of metal emitted when MIG welding, and I used to have these on my glasses 😉 Not sure you should wear a Rolex when welding, but the watch apparently can take it.
No lack of dirt on the case as well.
That will need a bit of cleaning as well 😉
The usual dirt under the bezel.
First look at the lovely bottom plate after removing the dial and hands.
The auto winder assembly. The detail of the execution is stunning.
The top plate without the auto winder.
The gear train.
The great wheel (the one driven by the barrel, and the only wheel still in place) doesn’t want to come out, and there is a reason for that.
I don’t want to force anything, so I remove everything else before trying to get the great wheel out.
Time for the bottom plate.
Again, everything beautifully made.
The date changer lever has a bit of corrosion on it and will need some cleaning up.
The great wheel after pushing it out of the jewel. The bottom pivot is damaged, and had a lot of almost crystallised lubricant on it, which had turned extremely hard, and had worn down the pivot. A new wheel is in order.Off into the cleaning machine.
I start off by applying a thin layer of braking grease to the barrel.
Then the new mainspring goes in.
The barrel bridge in place, and the balance jewels put back in and oiled.
The new great wheel.
The new great wheel turns freely, and I can continue to put the movement back together.
Gear train and pallet fork back in place.
I drop the balance in, and the movement starts beating.
After correcting the beat error, it’s still a bit fast, and I will adjust that after having let the movement beat for a couple of days.
Time for the bottom plate.
The date disk goes in.
And the dial and hands are put back on.
Charles from Watch Glass Cutting has replaced the crystal and polished the case and bracelet.
I case the movement.
And adjust the beat rate to +3s/day in dial down position, which is about as close as I can get to +-0s/day average in all positions.
The new gasket gets some silicone grease.
And the watch is back together.
Charles did a great job polishing, and all the welding marks are gone.Looking great again.
