      I actually have a couple problems I could use some help with. I’ll start with the more serious one I guess. I don’t have any trouble getting the back off my watches or changing the battery, but every time I use my tool to snap the back back on, something happens to the crown pin. It just lets go and comes out. I thought it was a strange occurrence the first time but I tried another one this week and got the same results. I’ve done this same thing on hundreds of other watches of different types and brands but never ran into this problem before. Can someone please help me figure out what I’m doing wrong?
      Also, a couple of my watches don’t seem to be able to adjust to my teeny tiny wrist size. In my Monarch, the majority of the links don’t have holes to remove the pins. Is there any other way to remove a couple links. Any advice would be appreciated immensely!!!

      Hi, new to repairing, just getting my feet wet, so be prepared for me to use incorrect language, and have things explained like I'm 5 :)
      A couple years ago, I purchased a Seiko Sportsmatic Weekdater, cal. 6619-7050. 
      Soon after purchase, the crown detached from the stem, and I took it in to local watchmaker for repair. It was returned in apparently good shape, but actually the problem still exists. 
      I'd like to learn how to fix the problem, and hopefully bring this watch back to my wrist. 
      It appears that the crown screws onto the stem, but that is as far as I have got. 
      Any assistance would be welcomed. I did find a service manual elsewhere, but I'm a bit lost as it's my first.

      Hello Everyone.
      I need some help with repairing my Emporio Armani ar-1922.
      I've watched some videos on YouTube but none of them resemble the movement of this particular watch.
      My first problem is removing the stem/crown. I cannot see anything which looks like it will release the stem and I don't want to poke around inside it any more for fear of creating any damage.
      Any help will be much appreciated.

      Hey, so I have a question. I've got an Invicta dive watch with a NH35A movement here that whenever I unthread the stem and crown as it is unthreading the date starts changing. Once its unthreaded I can change it to the 1, 2 and 3 positions and set and wind it accordingly. How can I fix this and what is causing this? 
      Yours truly, Josh

      Hey guys, my name is Lorenz. I am an 18 year old electrical engineering student from Germany. 
      I got this Breitling chronospace a56012.1 from my granddad and I want to repair it.
      Besides a slight clicking noise while turning the crown ( someone please let me know if this is normal ) it works just fine.
      My main problem is that the black color on the Bezel is worn out on some positions and I dont know where to find a paint that holds on the metal nor do I know how to paint it again.
      I have worked with watches already, I disassembled a mechanical movement cleaned and oiled it again so I feel pretty confident in doing this job.
      And I would also like to change out the crystal, does anyone know what size crystal I need for this watch?
      Thanks in regards for any advice.

    • Perhaps it did migrate, but someone initially stated that 4-jaws would be better, without referencing hobby machining. I think there is a reason why self-centring 3-jaw chucks are the usual choice for watchmaking. I rarely do any eccentric turning, but I do have a faceplate which I can use. Back to the original post: I can recommend getting a Burnerd or similar quality 3-jaw (German, Swiss, English, American). The Sherline chuck which jdrichard describes sounds promising too.
    • Further to John's remarks, -I would advance the hands by 12hrs, if the fault is in the calender mech then it should loose time during the day. -Note how long it runs on bench following a full day on wrist. This points to the area the fault is at.    
    • Does your app measure amplitude? Then what was your definition of fixing the watch in other words what have you done to it? One of the reasons automatic watches can have issues is if they just run out of power. It's why asked if your timing app has amplitude measurement. So in other words when the watches on the wrist it manages to keep enough power to be running as soon as you take it off your wrist did just runs out of power. Then next day's your watch still running or is it just off by a couple hours? Another Guess since basically were guessing without enough diagnostics information. I see from the picture at the link below it appears to have a calendar mechanism? There is possible you're losing your time during the calendar change but as I said it's just a guess.   http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&&2uswk&Orient_46941  
    • Hi has anyone tried printing bezels for vintage timex watches? is there a known supplier or does anyone have any 3d models made i could use to try it. thanks
    • Hello, I finally managed to fix my fathers watch which is the reason why I started learning watch service and tinkinring, the thing is the watch runs perfectly and keeps good time as long as I'm wearing it but it's losing like 2 hours during the night when it's not on my hand. I've tried leaving it both dial up and down but it made no difference, I checked the timing with the Tickoprint app and it's -15 s/d if I remember correctly. The movement is 46941 if that makes any difference. Thank you and have a nice day.
