Release mechanism tutorial , a how to

[rbj69]

ok many know me by now and know i type as i speak , plain english and no big words , but im guessing now u guys know me and can understand me , well at least i hope u can lol what i will be showing u is how i fix the release mechanism if u push it out of the socket so to speak, this one was pretty bad he bent some things i had to straighten out and piece back together, ok lets start , remember my pointer is the screwdriver ok

first of all u take the hands , dial and datewheel off , this is a mbw, so there is glue to tend with and u have to be really careful while taking the dial off or u could bend it

pic of the , hands ,dial, and datewheel and top of the movment once removed

im pointing with a screwdriver in this pic to show u the release spring for the datewheel u simply push it in to release it , also the big screw underneath my screwdriver/pointer i loosend a bit , reason for that will be coming up

this is how it looks when u push the stem release mechanism too hard notice how the sparts r bulging outward

now the fix, we have to remove the top plate , remove this screw

remember that screw below the datewheel release spring i said earlier u need to loosen but not remove here is why , when u do this it makes it easier to pull the top plate out

see the little lip on the top plate , it slides under that plate/big screw i loosened at the datewheel release spring , here is the little lip and where it slides under

now u have to loosen this screw and remove this piece , i dont know the correct name for this piece but u can see what im doing in the pic . also where that screw driver is do u see the bend in it, this where the person pushed really hard and bent this piece way on the other side , u really have to push it to achieve this bend lol hey he didnt know and i commend him trying to do some work himself , sometimes trying something is how u learn

another shot of the bend at the screw

ok now u have to remove the little arm im showing it simply pulls upwards off the post im pointing at

now u pull the stem release mechanism out to reposition in its correct place , like a puzzle

backside shot of the pusher , this post im showing is what u actually r pushing on to release the stem from the movment

now all u do is reverse everything i just showed u and put it back together some key points is in this pic, make sure this arm is around the little post on top of the release mechanism

and make sure u push the u shaped spring over to the side of the little metal piece im showing , it is spring action and when u push the stem in and out to change date or time , it helps push the arm up and down

after u get everything lined up and positioned correctly , u put your top plate back on like so making sure u slide the little lip back under that plate im showing and tighten that screw and put your top plate back in place and tighten it down

this is how it looks with it all in order and as u can see the bent parts r straight and looking good , lol

after pushing in and out the stem testing it now u can put your datewheel back on , u have to push in that little spring i showed u at the top to get the datewheel to lock in position

now it all works properly , and u can smile and now take a breath of air lol

enjoy , i know im not a english major and i never claimed to be, i tried to make it fun and simple for u to understand

just wanted u to know if u try this at home u have to have patience and if u r nervous or shakey i wouldnt recommend working on watches lol cheers

now for the best part after a job is completed ..... BEEEEEEERRRRRR!!!!!!!!!!!!!!!!!!!!! LOL

Replacing the spring is the hard part of that job

That spring takes off like a bat out'a hell into the land of unrecoverable watch parts

Nice post Joe. We just need to be careful when removing the stem we don't push the release pin too hard. Use the right size screwdriver = 1.2mm

Great post - be carefull if u guys try this yourselves.

U need patience and a lot of experience with the board game called "Operation".

If you're good at that game, then u might be steady enough for minor watch tinkering.

nice joe
