Crown position when removing stem.

Absolutely not. It needs to be all the way in. Else it will never more work and you have to disassemble the whole movement. Although this is more vital for 2836 and 2824 eta.

That explains my struggles with the 2824 I was working on. Thanks President

You're welcome. I learnt throughout the years by a lot of mistakes but now can completely disassemble and reassemble 7750, 2836 and 2824 and lower stuff. Removing and replacing stem and crown can be very frustrating if you don't realize that a lot of stems have just a little bit different dimensions. Never push hard but carefully and softly try to get them in and find the right opening. If you push too hard also the whole composition of parts is out of order and you have a much bigger problem.

Of a 7750 Valjoux?

It's very easy. Unscrew the crown. Then press the button close to the stem, not too deep, just like half a millimeter. You can pull the crown and stem out.

To place back just bring the movement in position, don't attach the holding clips to the movement yet. Carefully push the crown in the hole and turn it a bit until you can push it easily further to the point that it's against the bar connected to the button for removing the stem. Push that button and the stem deeper and let the button click back. Now the stem is locked again.

If you haven't done this before, I would advise against it my friend.  Even when you have experience in watchmaking, the method of extracting the stem differs from one guy to another, myself personally pull the crown out to time setting position, and gently push the stem release button whilst gently pulling the crown outwards.

As said, I only choose this method due to the way I handle the movement afterwards, and this is dependant on what i have already disassembled from the dial side of the movement.

Get a watch repair guy to do this for you if cleaning the dial is your only reason, you may well screw up the keyless work, and then be without the watch until you get it repaired.

Yes, I work on genuine brand watches for my day job, and unlike most in my field, I am happy to undertake repairs of some replica watches too.  I'm moving premises in a couple of days though, and won't be back up and running until the end of January, so drop me a pm, and I will give you my email, and you can email me, I will then email you my price list, and then if you wish, get back to me end of January, and I will get you booked in.
