Hi ColBlimp
Without wanting to sound rude, the simple answer is....
If you need to ask this question, then best left to the professionals ie a watchmaker.
The less simple answer, if you're not put off is....
Re the dial - leave well alone - it'll only end up being ruined.
Re the movement - if it's running poorly, not really worth servicing. Better to buy a replacement quartz movement. Cousins material house in the UK sell replacements that drop right in. Can't remember the price, but the last time I fixed some CWC's, they were well under £10 each.
Hands and dial can be relumed if you have a steady hand. Again, luminus paste can be bought from materials houses such as Cousins.
Tools you'll need - ideally a set of hand removers & some watchmakers screwdrivers. That's about all for a quartz CWC. I have some pics showing some dismantled CWC's. If I can find them, I'll post them later.
Cheers
