Robert from the US sent in this Rolex Yachtmaster, which is of great sentimental value to him.
The watch doesn’t work, the second hand is stuck under the hour hand, and the movement rattles loosely in the case.
He previously sent it to a service centre in the US, which quoted him a good $1000 for a service. That’s why it’s here with me now …
The Rolex calibre 2135 movement is one of the best ladies watch movements. It beats at 28,800 bph, performs like a trooper, and is a pretty sturdy beast. It has a quick-set date, is automatic, and that’s all you need from a movement!
With the second hand dislodged, the movement starts up, but with a very feeble amplitude.
Time to take the movement apart. Here is the auto winder assembly.
A beautiful movement, and nicely decorated.
The mainspring with the usual old grease. I will of course replace it.
The bottom plate with the date ring. Note that the date ring is suspended by a large jewel. Very nice construction!
And what lurks below isn’t bad, either. Great finishes, jewels everywhere,…
And off into the cleaning machine.
I start off with the bottom plate.
And then put together the movement until it starts beating. Note that the escape wheel is capped from both sides.
Straight away, great performance. Very little positional variation, and a constant beat rate.
I put the dial and hands back on.
And put a new case back gasket in with a bit of silicone grease.
Now the auto winder goes back on – note the new case screw on the left.
And ticking again. Robert wants the watch to be left as original as possible, so the crystal is still the same.
