How to remove the dial/movement from a KW PAM389 case. Tutorial

[chris3007]

I work at my KW PAM389 to improve the winding construction of the A7750 movement.

http://forum.replica-watch.info/vb/showthread.php?t=205473

At this point I ask myself "how is the dial/movement fixed to the case?"

And the answer is very easy.

Let's see how it works.

First open the watch and remove the CG and the stem. To remove the stem from a A7750 you must pull the crown too the set time position and than press this little button.

But don't press too hard. Be careful with this button

Now you can remove the stem.

This is standard at a A7750 movement and you can remove the stem also with the p.9000 deco plate at the movement. but now we come to the interesting part of the PAM389 case construction. How is the movement fixed too the case.

Normally it's just fixed with this 2-3 little clips.

But not in this case. This clips just fix the movement too the dial. And the dial is fixed too the case. So you have to remove the dial first because of the hands.

But how is the dial fixed too the case?

Just with this little black "things"

6 of this little black plastic bolts are just pressed in between the dial ring and the case.

Too remove this bolts you just need a small screwdriver and push this bolts too the slot at both sides of the ring

If you have the bolt at the slot you can easily remove it with a tweezers

If you have all 6 plastic bolts removed you can pull out the dial/movement construction from the case.

Here you can see the groove at the dial ring for the bolts

And the opposite at the case

This can be necessary if you have dust at the dial or you have to re-aligne the dial to the bezel. Or if you want to do a lume job of course.

Amazing, thank you

Interesting way to hold a dial in place. Thanks.

also, it's a stem not steam.......

Hehe, damn iPhone autocorrect. Thanks for the hint [emoji2]

Another great tutorial Chris!
Now I wonder if the gen has the same construction?
Maybe it's unlikely, due to different movement, but it still would be interesting to know.
Good job

Chris I'm going to prepare a canned reply for your tutorials. LOL
Amazing and really useful

Congrats again

The interesting thing is the inner movement case has no metallic connection to the outer watch case because of this plastics bolts (except the stem).
It "floats" more or less in to the watch case. Maybe this helps to be more antimagnetic.

Great work Chris.
I wonder of the KW Pam 382 is constructed this way also?
My dial needs slight re-aligning to the bezel. Might just have a go at this to see if it can be done.

Chris, another great review. What i like the most is how clear and well organized your pics are. Usually tutorials have pictures but they are blury or unclear of what step is actually being performed, your are very clear and therefore usefull for someone trying to follow them step by step. Very well done.

YES I agree

This is the useful way to make a tutorial. Showing people clearly step by step with good explanations and GOOD pics

To encourage people to do it by themselves

That shows that Chris Tutorial award was well deserved not only for the awarded post. This is the way to prove it

Thanks

But how is the dial fixed too the case?

6 of this little black plastic bolts are just pressed in between the dial ring and the case.

Too remove this bolts you just need a small screwdriver and push this bolts too the slot at both sides of the ring

If you have the bolt at the slot you can easily remove it with a tweezers

And the opposite at the case

This can be necessary if you have dust at the dial or you have to re-aligne the dial to the bezel.

Looks like dial tilted a little bit too the left after a month using the watch.
To re-aligne the dial to the bezel, how would you preceed?
Remove the bolt completely and re-install them (how?) with dial in the right position?
Just "pushing" with a thin screw-driver through the gaps at both sides?

In other words, can that be done?

While those plastic bolts give some more shock resistant,
the fact is the whole movement "swims" inside the watch case.
So, that would make imposible to rotate the movement to align the dial better, since there are no metal mounting plates secured by screws. You can rotate the movement quite easy but the moment you snap the crown to the standard position, the whole movement moves to that "stress free" position and the correction applied is lost in the same moment.
As someone said in other thread ... "That is by design".
So the important thing, here, is to have crown tube at the correct position on the case.

Thanks in advance,

Great tutorial and interesting design they use to locate the movement. Probably also better for shock resistance.

 

[chris3007]

The movement/Dial sit very tight in the case with the plastic bolts. If you can rotate your movement quite easy inside is something wrong with the plastic bolts.
You need some force to rotate the movement inside the case. The stem alone don't move it back normally.

Nice write up! The "plastic bolts are a very odd feature, although I guess they would provide extra shock protection, so they could be a gen feature. I'd love to know more.

 

[slaughterer62]

In other subs, a simple rubber gasket/washer is used instead of the plastic bolts.

Awesome tutorial.

Is is there a similar tutorial for Seagull movement?

 

[plyschbyxa]

@chris3007 is this the same method of removing the dial/movement from a H factory PAM243?

Thank you for posting this, and taking the time to get really good Pic's Chris!

Truly helpful info here Sir! ;-)
