This is Jason’s second watch – another diver’s watch, an Orient with the calibre 46943 movement. It’s in need of a full service, and that’s what it will get.
There is a bit of a beat error, the amplitude is a bit low, and the escapement has some dirt on it.
The dial and hands are in great shape.
The bottom plate with the day ring removed.
The auto winder assembly.
The gear train after removing the wheel bridge.
Only the centre wheel with its bridge left.
The mainspring has dried-up grease on it, but otherwise is looking good. As I can’t get hold of a new mainspring, I will use the current one.
And all goes into the cleaning machine.
I start of by putting the balance jewels back together.
And the cleaned mainspring goes back into the barrel.
The centre wheel and barrel back in place.
And the basic movement is back together and ticking.
The beat error is now perfect, we have a decent amplitude, but the graph is slightly wavy. This isn’t a new movement, and even a slight wobble in one of the wheels will lead to this. Nothing to really worry about.
The bottom plate is coming back together.
Everything ready for the day ring.
The auto winder bridge is back on.
And I can case the movement.Beautiful watch!
