  1. Hi everybody, I'm on a very simple project. I would like to assemble a watch. I have look at "Build Your Own Automatic Watch - Using parts from eBay" who was very clear and well done! I would like to put a Miyota 8N24 in a case who can fit a Miyota 8215, since I don't find any case specialise for the 8N24. This two movement have the same diameter but the 8215 have bigger height. 5.67mm vs 5.55mm fopr the 8N24 On the "shemas" they seems to have the same base, but I'm clearly not an expert. I realy want too biuld a watch with a Miyota since I like japanese watches. Thank you for your advise ! OwL
  2. Hi Everyone! I have been practicing watch servicing these past months. So far I have successfully serviced a ST36 (ETA6497 clone), thanks to Mark's watch repair course which is awesome! I have also tried to service a NH25A, and messed up the hairpsring (replacement on the way), and a Miyota 8215. Everything was going well with the 8215 until I reassembled the train bridge and noticed that the escape wheel wobbles when I turn the wheels. My guess is that I accidentally broke off the upper pivot during cleaning. I was looking for a replacement escape wheel and found it at Cousin's, but they are out of stock. Anyone know any other place I could get one? Thanks. PS: Trying to keep a positive attitude after messing up two movements, but practice makes perfect. :)
  3. Hello watchmakers! I am about to work on a vintage citizen watch. I removed the movement from the case but I am stuck on removing the automatic rotor.. It seems that my screwdrivers won't do the job.. Any advice would be helpful thank you.
  4. Hi everyone! I am currently in the process of building my first watch. I have sourced the parts from ebay and decided to go with a Miyota 8215 movement. I believe I have everything I need, have learned a lot from watching the videos , however I am still scratching my head on a white movement ring that the Miyota came with (picture attached). Is this the dial spacer ring or does it function as both a movement ring and dial spacer? The case I purchased comes with a movement ring (however I have to purchase the clamps and screws, which I have already found on Esslinger). If this is not a dial spacer, I am assuming I would need one so the date ring doesn’t get stuck, however I am uncertain if the dial spacer is totally necessary. Thanks in advance! Guido
  5. Hey everyone, I cant find out how to get this drown off and I've tried everything. The Miyota JS25 movement says PUSH and points to a hole which I've learned means this is where you press to reease the crown but I still can't get the crown out no matter which position the crown is in. I first tried with the crown all the way out then with it halfway in, then all the way in and haven't been able to get it out, please help.
  6. Miyota Automatic Service - "Three Screws to Rule Them All" Now for something completely different, a Japanese Automatic from Miyota. This is a budget driver's watch from a fashion brand called Scorpion, and I had no idea what I'd find when I removed the caseback :huh: Whatever! I just wanna work on watch movements, increase my knowledge, and the repertoire of movements I've had experience with. It's also a blessing to post these to help people with reference photos and walkthrough of various movements. When put on the timegrapher, it was quickly obvious that this movement was not running well at all. Extremely low amplitude, high beat error, and a graph that looks like the pepper in your mash potatoes :P Well, it happened to be a Miyota Automatic Movement ... I have no idea of the caliber, as there are no stampings on any of the plate ... beside the brand name. Once removed from the case, I pulled the Hands... ...and then the Dial. After that, I flipped it over and removed the oscillating weight to get a better look at the movement itself. Notice anything scary about this already?? There are only 3 screws holding the complete movement together!! :o Ack!! Visions of the Seiko 5J22A Kinetic "Auto Relay" , with it's 9 pivot gear train plate flashed before my eyes!! This was NOT going to be fun putting back together :P But I do so love a challenge. As per usual, I removed the tension from the Mainspring, and removed the Balance and Fork. Note: The red arrow is pointing to a very thin spring which you pull back to disengage the Click. Here's a closer reference photo of it after I'd pulled the plate off So as the title says ... Three Screws to Rule Them All .... Bam! The whole movement has to be located into ONE plate, that's only held by three screws ... this is not Rolex quality gentlemen ^_^ After tipping the movement up-side-down and telling the complete movement fall onto the desk (just kidding), you are left with only the Centre Wheel. Once the Centre Wheel Bridge was removed, the fault with the movement running so badly came to light ... RUST on the lower piviot! Rust also on the Pinion Over to the Calendar and Keyless Work ... looking way over complicated for a simple Date Wheel, as all the springs are there for a day complications as well; minus just the Day Wheel :( ... Gotta love cheap movements. Reference photos of the Keyless Work. One last thing to note with this movement. The setting lever is riveted into the Main Plate, so it's not able to be removed. Well this little gem is in the Watch Cleaner, and I've got a few weekend chores to do, so I'll put it back together tonight and post the results later. Hope you enjoyed this write-up, and got a few giggles out of it as well :)
  7. Is it possible to purchase parts for a Citizen 8228A (Miyota) movement. I have a rather beat up old example, which is missing the tip of one of the winder gears. I suspect the answer is going to be, no, you would need to find the parts from another damaged example. I did look on Cousins, but the part I need is not listed. Initially I suspected the only issue with it was the balance, and spent a little time tickling the hairspring back into shape, only to then figure out that while the winder made the right noises, it wasn't actually driving the mainspring, due to the missing pinion tip.
  8. My Beuchat Apnea has been a work horse for nearly 10 years (bought it the 11th Feb 2008)...up until a few month ago when condensation appeared inside after a shower (which isn't that great for a diver ). I let it to rest in a warm (not too hot) place with the crown unscrewed and the water disappeared. Worked for a few more weeks and that was it.Today, it only ticks when I wind it : the second hands moves while I manually wind it and stops as soon as I let the crown go. (That makes me think there's something wrong with the main spring...which makes me think it's unrelated to the shower incident).When I unscrew the back, I don't see anything obviously wrong (by that, I mean I didn't end up with a spring in my eye).For the price of a service, I can buy some tools and actually learn some skills. I know some will think it's a bad idea but I insist on doing it myself, hopefully with your guidance. Would you guys be able to guide me through that? I think it's a Miyota 8215 (Miyota, I'm sure, it's written on it )
  9. Hello! By any chance, does anyone have the service manual / troubleshooting for the Citizen U600 movement? Thank you, Bogdan
  10. My engagement watch was a Briel, which turns out to have a 0S60 Miyota movement. I paid goldsmiths to replace the battery, boy what a mistake. When I collected it the crown came off in my hand. Goldsmith said they can't repair!!! They paid me £250. So this is when I did some research and took the back off the watch. I believe the stem is still in the watch. But I think I can repair by replacing the stem and crown. I still have the crown. Could some one advise what stem I need and how can I attach the crown, doesn't appear to have a thread but I think it should have. I can get more photos if needed. Many thanks
  11. Hi all! After introducing myself I started out with demounting the AS1900 movement. I now came to a point to assemble a watch by my own. I bought the Miyota 8215 series movement (pictures in attachment). I really want to make a dress watch. Therefore i'm searching for a fitting case with dial and hands. My question is now, before I purchase all products, does the 8215 movement fit with the following case and dial? Movement is the image in the attachment: (already purchased) Case: http://www.wenping1970.com/40mm-watch-case-sapphire-glass-fit-dg2813-3804-eta-2836-miyota-82-seriesp488_p1527.html Dial: http://www.wenping1970.com/debert-345mm-white-dial-fit-miyota-82-seriesmingzhu-dg2813-movement-mens-watch_p1533.html Hands: http://www.wenping1970.com/debert-watch-hands-fit-eta-2836dg2813-3804miyota-82-series-movement-mens-watch_p1531.html If you have any other suggestions for buying the case/dial/hands for this specific movement, I really would love to hear about it. Have a nice weekend! Kind regards, Jorick
  12. I am looking for a stem/crown for a Miyota quartz movement (see attached). Why does Miyota seldom write the movement's part number on the movement? Can anyone help? It goes inside a cheap Nelsonic LAX 766 watch.
  13. Hi everyone. I'm servicing a TIAHUA watch, the movement is a Miyota GL02 with 3 hands and day/date at 3. Does anyone know where I can source one, or know its equivilent replacement? Regards to all
