Hi Andy,
BDLJ's advice to let down the power on the mainspring would be good except that the broken teeth on the ratchet wheel are going to prevent it from turning and allowing the power to be released. You're going to have to do something a little more dramatic to release the power I'm afraid, and your best bet may be just to remove the screw for the ratchet wheel and pry off the ratchet wheel by wedging a screwdriver blade underneath it (expect some drama at that point, perhaps flinging the ratchet wheel across the room for example).
Then you can start with the balance bridge and the other bridges as BDLJ mentioned. If you want to remove the crown wheel (the other wheel on top of the bridges after the ratchet wheel, you can remove the bridge without taking it off), you'll want to know that it is almost certainly a left handed screw , so turn it clockwise to release it.
Enjoy and expect to break stuff and then you won't be disappointed when you do.

Tips on taking a movement apart required please.....
I have an old movement in a watch case which I have had for years...as you can see there are some broken teeth on one of the wheels and their is no spring on the escapement so obviously it has never worked since i've had it. I would however like to take i...
If you're not scared of damaging it...
....then I'd start by winding down the mainspring (if it's at all wound). The click for this is at the 11.30 position in that first photo. Just push back (anti-clockwise) on the little lever with a toothpick or something so it disengages from the gear tee...
Thank you, thank you....just what I was after....
it is actually fully wound but I never knew how to unwind it. I will be careful with the broken cog and let you know what happens, might take pics just in case anybody else is interested Yours my friend, Andy.
Anytime.
...feel a bit embarrassed giving advice when there's the likes of John D on the boards, but if all you want to to is attack and wreck your watch...well, I feel qualified to provide assistance in that field.

Has any watchmaker lost an eye?!
Sounds dangerous, John. Reminds me of an old cartoon of a bomb disposal practical exam for first-year students. The consequences of failure were high! A
I know a watchmaker who always puts on safety glasses for mainsprings
Installation or removal. And also for springbars. Yes, others make fun of him a little. _john
What you get when a rank amateur...
....gives advise - missed basics all over the shop! Thanks, John, I read Andy's comment but didn't spot the busted tooth jamming it up.
Thanks for the extra info....
it obviously isn't a family heirloom but I'm just interested in seeing what is inside...maybe (but doubt it) fix it if possible but either way I'll be more knowledgeable about it soon. I'll take on board what you said and let you know what happens. Yours ...
A small suggestion
If you're doing this at home and things could go flying around, do it in a room with hard floors or else lay down some newspaper on the carpet. Those tiny bits can be hard to find until you step right on to them. Regards, Richard.
"try" being the operative word
You will almost certainly drop something, so RJW is just suggesting that you plan for that eventuality. If it's not really important that the watch ever run again then of course this is not critical. _john
sounds like the height of boredom matey,
you should come down here and help me sort my crap out ready to move. only the cellar to do now. big cellar, lots of rubbish i've thrown out about 50 watches or bits of watches over the last few weeks. you could have filled your boots playing with them. h...

Typical...

Little advice
Hi Andy, It is interesting to fiddle with watches. You will learn a lot too. I would advice you to take photos in step wise as and when you find necessary when you strip the watch. This will help you to refer to these photos While you assemble the watch b...
Cheers Ed...
it should be a fun evening or so to take it apart - not sure if I'll get it back together but you never know..!! Hope you and the family are all OK, Yours my friend, Andy.
Taking it apart is the easy part..
But I guarantee you much more satisfaction when you successfully assemble it back and the watch starts ticking. (Of course you need a working watch for that). You could practice with this watch, get your hands steady and gradually work on a working watch ...
