MSR was created by Revue to manufacture movements. Just like Eterna created ETA. This is their automatic T56.

I remove the osculating weight.

Movement out of the case.

Hands and dial removed.

I start taking apart the setting/ winding mechanism and the date mechanism.

Here you can see gear train layout.

I have cleaned the movement and it’s ready to be put back together.

I fit the mainspring into the cleaned barrel.

I see that the balance moves freely. It was a little deformed and got a little tweak.

The movement did not move freely. The sweep second wheel was touching the third wheel, so I replaced that.

Oops I forgot to take apart the clutch pinion. The hour and minute hand are driven from the barrel via this pinion.

Best way to remove the pinion is using the Platax  tool

I clean the pinion and lubricate it. I press the clutch back onto the pinion using the staking set.

You can see how the pinion comes up and the clutch engages with setting mechanism.

Gold dust, new sliding pinion and winding pinion.

Setting/winding mechanism almost back together.

Date mechanism back together and very snappy.

Movement almost back together.

Base movement back together and ticking. I actually had to take it apart and back together a few times to find the bugs ailing the movement.

I’m happy with that!

Dial and hands goes back onto the movement.

Movement goes back into the case.
