      Hi all,
      I'm currently building a custom watch with an ETA 2892-2 movement. The movement is from an old Brietling. I managed to fix it and was working perfectly. I was in the process of putting it all together, was attaching the second hand and it suddenly stopped. I believe I may have used too much force. However, I have taken the watch apart again (about the 12th time!). I notice that when I move the hacking spring it stops as it should, but when I return it to the position that would usually allow the movement to move again it doesn't. I assumed I'd knocked something out of alignment, but to add to the confusion if I give the escape wheel the slightest nudge it continues ticking. It's baffling me. 
      Anyone have any ideas?
       
      Best,

      Hello,
      I have been asked by my stepfather to service his Sanford Bros HF 36000 automatic watch bought new in 1977. On starting work, I noticed its an ETA 2832 but on looking for the technical sheet, I can't find one anywhere. Perhaps it is a rare movement but maybe there's an equivalent document I can use. My first main concern after removing the rotor is how to remove the auto-wind assembly - looks quite complicated and this is only my second attempt at an automatic movement. I've added a few photos for reference. Of interest, Sanford Bros was a small watchmaking company in the '70s based at 321/323 Oxford Street, London W1. He still has the original sales invoice!
      Would anybody be able to point me in the right direction please?
      Many thanks

      Join me as I strip down, service and review this Chinese ETA 2892-A2 clone. Seagull ST1812 watch movement. There was a couple of issues to deal with but altogether a fairly impressive movement for the price.

      Hello Mates!
      Im working on an ETA 2783, and suspect that the canon pinion is to tight against the lower wheel.
      So I have to make it a little bit more loose...
      Has anybody done this befor? 
      And how it the best way to do this?
      Thanks   A
       
       
      ETA type of Center Wheel/Cannon Pinion

      Cheers Mates!!
      Working on a Tudor Oyster Prince with ref no: 2081/4     with a ETA 2784 movment.
      Cleaned and inspected, all looks good, no sign of wear and tear on the main spring, no sharps bend, looks overall good. Noticed that there where some marks on the barrel wall. But that I have seen before witout any drama....
      Oiled it , put togeher , goes like a dream..... but the the spring does not stick, it snaps over after 6,5 turns by crown.
      So the question is:
      Can I just replace the main spring?
      Can I just replace the main spring and do something with the barrel walls ?
      Buy a new barrel with spring? Is it to be sourced?
       
       
       
      Ref 9081/4 is the ETA 2784

    • Hi   All advise given is wise and should be noted, also consider lightening the inside of any desk/work place so as to give good reflection of light. My workbench is covered in white lino tile, a pale green as per the bergeon mats etc.  as Marc says the roll top is probably the best option.
    • Brilliant HSL nice of you to share the data  Thanks.
    • Thanks for the encouragement. I think it has to be a right-hand thread on the arbor, due to the direction the spring is acting. The mainspring did indeed have quite a bit of power left in it. There was a buzzing and a whirring for quite a while after I pulled out the balance, so it seems I have been very lucky indeed! I will check everything carefully again for damage. I have already found one cracked jewel.
    • That is (almost) identical to the part I have. Could not have wished for better support, thank you! I do not have the two holes in the barrel arbour, so I can't use a compass or similar to unscrew it. I will try gripping the circumference with something. The action of the spring suggests it is a conventional right-hand thread, correct? Part of the stop-function (the disc with the finger on it) was missing when I opened the case, so it may well have been broken by another bodger who got there before me. I have the Maltese cross part. I may have a go at making a replacement if it's not too difficult. Would you have a picture of the part I need? How is it held in place?
    • HSL- I am new to this and know the above will help me in the future. Thank you for sharing.  I believe and apply pay-it-forward :ThumbsUp:
