      Hi Guys, 
      Hope this finds all well, i have started disassembling a rotary watch with a skeleton movement and a tiny part fell out of the movement which i was not in time to take a picture. If anyone has ever worked on similar movement and know where it belongs i will appreciate your help.
      Pictures attached.
      Thank you in advance.

      I am trying to remove a mechanism from a Rotary Kensington GS02490/06, it's a front loader, any suggestion?
      The front,hands and stem are removed.

      Hi all,
      I have a Bulova sine plate with integral rotary table. It doesn't have any locking features for the plate so I don't think it was used for machining. The rotary can be locked and it does accept a dovetail block that can be clamped in place. Has anyone seen another, know what they were used for or when it might have been made?

      Hi all, 
      First time ever trying to fix a watch. It's a Rotary Editions 500series. Opened it up and the part in the pic was swimming about loose only issue is I have no idea where it goes. 
      Any help would be greatly appreciated.

      I have recently bought a 'non working' rotary automatic skeleton watch. I love the watch to bits however...
      The watch will only work when fully wound and as it unwinds (with little wearing) it stops. it appears as though the minute hand is ever so slightly fouling on the hour hand. when full wound there appears to be enough power to override this. I'm hoping I can just tweak the hand very slightly to clear it. it visually appears slightly bent up.
      Ive had the watch open fairly easily however I cant for the life of me find how to remove the stem/crown. ive searched high and low online and am now fairly familiar with the process on many watches except this one.
      Any pointers would be much appreciated and well done on great forum.

    • Hi all and thanks for all info. Will start to go through it all over the week end. I have also looked for a way of letting down the m/s. I can see that the ratchet wheel is on the ”wrong” side though. And there seems to be a few Junghans made that way. The Ranfft samples are not identical though, if I look at the bridge designs. It’s just running as it sits right now so I will let it run out the ”natural” way before attempting anything. Sent from my iPad using Tapatalk
    • There are a few Buser movements on 17jewels.info and ranfft.de but none are an exact match. This is similar in construction but a different shape. -> https://17jewels.info/movements/b/buser/buser-75/ Which suggests it may be a Buser movement, but beyond that, there is little information.
    • Thats a new one for me. It did find some movements maked as  "Nidor"  under the trade name of "Buser" This is one of those watches that you will just have to repair without any manual/tech guidance. However I can not see any obvious way of letting down the mainspring which would be fatal for the watch without this first step.

    • That doesn't look right to me. Looks very amateurish, could it be a fake case?
