Update: I finally managed to find the time to move ahead... I abandoned trying to diagnose my 8200 and got a 8200 clone and got it onto the dial no problem. QUESTION: Unfortunately the day wheel isn't moving very smoothly (worse than the orignal 8200) using the stem (date moves fine though) Is there any way to fix/diagnose that? The other issue is the stem (and stem receptacle in movement by association) isn`t exactly the same design as on the 8200 which is very unfortunate- the locking notch not in same position on the new stem, so looks like i`ll have to use the flimsy stem that came with the clone movement. not sure its long enough. I guess it could be worse. as long as the stem is the right length and diameter, should be usable. I could ditch the clone and get an 8200, but i'm at the end of my patience scale with this project...

"The date window in the dial is made for the date to show at 4 instead of 3. " I don't follow. on my dial the day date shows at 3, and the crown is at 3.8. not sure what you mean? thx

I need your advice again... I'm getting a replacement 8205 as you suggested, either clone or original, not sure yet. A couple of questions 1) some sellers mention 3 oclock date in their ads. My case is 4 oclock (3.8 oclock). Does this mean there are 2 different variants of movements with different mounting points, or do the dial mounting posts do the job of getting the crown to either 3 or 3.8 o'clock? This is unclear. The mounting slots on my current 8200 with the crown position at 3.8 oclock are 6.3 oclock and 11.6 oclock (approx). 2) is there any higher end day date movement from miyota or chinese . that is slightly more $$ that would work with this configuration I have? Thanks for any advice. Note I can't use an 8215 style since I have day - date window on my dial (like 8200 and 8205).

i am getting a new movement then instead of fiddling around with wheels, i did get the stem bit out and i have 5 new stems now useless, replaced mineral glass with sapphire I received today, my press worked great. So now the challenge is wait for the movement, and get dial and hands off and on without damage, i just ordered the right tools for each task. I also have to glue the crown onto the new stem and check if those seals are still effective on push crown (it is a dive watch of sorts). Only question is, crown is 4 oclock, does this mean the dial mounting is different than 3 oclock? also what kind of adhesive do you use for the stem to crown? thx

the stem broke off beyond the movement edge, impossible to get a grip on it, had to remove the plate to access and push the other end (or did i have to?) anyways i did, and then lost a wheel which is a bummer because everything i removed except for that wheel is in a plastic container. i think im going to just buy a chinese replacement movement (or look for one in my collection of cheap chinese watches), move the hands and dial to the new movement, which will be another fun project no doubt, the challenge not to destroy those. my sapphire crystal should be here tomorrow, if the replacement goes well, i'll order the movement, if it doesn't (i.e. the crystal doesn't really fit) i'll have to reevaluate since too much time and aggravation. i have lots of watches so i'll get over it (i hope).

i found the answer, no it won't work with the 8200 hands since the second and minute hands hole diameter is incompatible with nh35. easiest solution is to buy 3rd and 4th wheels it seems. In your view, what are my chances as a (fairly handy and careful) beginner, of properly reassembling the top plate with all the wheels in proper place so the movement works without destroying anything. Is there room for trial and error on reassembly or more likely to destroy gears if not on right side or in holes properly? thanks

i don't suppose a garden variety nh35 would fit to replace the 8200 assuming hands would fit it ? thanks for your help

thanks, that's what i figured i found the 3rd and 4th wheel on ebay, 10 bucks each per set of three, not sure which one i have. my problem is i really like the dial hands and case on this model CITIZEN NH8381-12LB, and despite the barebones movement it isn't particularly cheap north of 200usd new, but the shrouded case and bezel are quite nice. I have a sapphire crystal on the way, which was the original plan to replace the crystal before i stupidly broke the stem moving the movement, which cascaded into the disassembly to get the stem out. The question now is whether i can get the movement back together and working properly if i source the missing 3rd or 4th wheel (how can i tell which one i have/need? does one have more teeth?). I tried to reseat the wheels i have and they don't seem to have obvious fitting direction or holes no markings on the plate etc. so probably a bit of trial and error.

Hi, I have been using your great post as a guide. I have a fairly new/seldom used marine master dive watch. Actually wish i had read it before. Anyways, I was planning to change the crystal and I broke the stem somehow right at the edge of the movement, impossible to get out, so I disassembled the movement from the back side taking the bridge plate off. I managed to get old the piece of old stem out, and my replacement stem looks correct. 2 questions - 1) I seem to have lost one of the 2 smaller brass gears (one of the 2 small ones that look almost identical) and i'm stuck and unhappy because if it landed on my clothes it could be anywhere in my house. Is this a "standard part" that watchmakers would have in different sizes, or is it unique part number only for this movement and has to be ordered as such? The movement is simply labeled 8200 (not A), and i bought the watch new around 2010 i think. Miyota doesn'T have it on their website, 2) I didn't realize that getting the bridge plate back on with all the wheels aligned would be so difficult (based on your description) and i worry i may not have all the wheels properly engaged - this is my first time reassembling a movement, so at this stage, i'm wondering if a) i should try to see if i can find a watchmaker who has the missing part if i can find the spec of it and then try to reassemble, or just abandon and find another use for the soon to be delivered sapphire crystal. I don't know if i would get a new movement, which isnt cheap and presents other challenges like removing the hands and movement from the dial and put on a new movement, never done before.
