Hi All,

I recently replaced the movement for my Tissot PR50, which was a standard ETA F06.111. I now need to replace the crown as the old stem was broken into the crown and could not be re-used.

Could someone point me in the right direction in finding a proper replacement crown? I don't know the size or how/where to measure to find a proper crown.

Thank you!

Cousinsuk has some Tissot crowns. You would probably need a new stem also. I would think the stem is 0,9 mm . 

I replaced the movement and it came with a replacement stem.

Further research shows that the stem provided is a Tap 10 Stem, I presume.

How should I go about sizing the replacement crown?

      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?

      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.

      Question for those who work on Vintage Timex watches:
      I've restored several Timex pieces from the late '60s to the late '70s.  The technique I learned (from Internet posts and tutorials) say to simply loosen the dial-side balance pivot by unscrewing it 1/2 turn prior to cleaning the entire movement in an ultrasonic cleaner.  This method contradicts the official Timex service manuals, which state that the balance should be removed, cleaned separately and reinstalled.  Thus preventing the hairspring form being damaged in the ultrasonic cleaner.
      My experience is this: 
      Leaving the balance in place (slightly loosened) is much easier and will work on the standard movements used in the '70s (M24/25, M32/33, M104, etc.) Attempting the same method on movements from the '50s and '60s (M22, M29, etc) will result in a kinked hairspring that is damn near impossible to un-kink.  So my question is this:
      What do you experienced Timex restoration experts recommend?  Leave the balance/hairspring in the movement for cleaning, or take it out to soak in a separate jar?
      Is the potential for hairspring damage greater when removing/reinstalling the balance - in comparison to leaving it in place?
      I've messed up a couple of vintage movements that I really wish I hadn't.   I don't want to make those mistakes again.
      Thanks for any insights!

    • I love quality but IMHO cost must be reasonable for the intended (hobbyst) use. So I'm putting the $32 link anyway  https://www.aliexpress.com/item/32634442471.html
    • Nicely done. I've only made 1 balance staff so far. I've got a German aircraft clock that has a broken endcap jewel that also had both ends of the pivots worn flat. I've rounded them again and once I've received the new reamers for my jeweling tool and fitted the new endstone I will find out if I will be making my second balance staff as it may now have too much endshake.
    • I think this could be done out of brass with a three/four jaw chuck. The threading would be very tricky...unless you do snap on. Sent from my iPhone using Tapatalk Pro
    • Thanks. Not sure how I would advertise? I actually love making balance staffs. The new DSZ-70 stereo microscope is great for examining my work and seeing any defects in the parts. Still cutting the part with x20 loupe however. Here is my messy desk Sent from my iPhone using Tapatalk Pro
