Orient 46943

Question

Hello,

First I would like to say I just got into the hobby. I've watch both courses and followed along with the 6497 movement. After going through the disassembly and assembly a couple of times I've decided to work on an old Orient from my dad that has been out or order for several years.

After watching a few videos and extracting the movement,  I noticed how much smaller everything is compared to the one used in class. While I'm currently awaiting for Level 3 in order to properly troubleshoot a movement I believe my issue lies within the Escapement (oscillator or pallet fork).

It seems to me the top pivot axis of the pallet fork is broken of very used up as I'm having a hard time getting to behave properly as I have seen it work in the 6497 and seen in videos online. While placing the oscillator has been the most challenging portion, I've gotten it to beat but it beats way too fast and erratic.

I've included some photos of the pallet fork and video of it ticking when I get it properly setup as I believe the missing top pivot prevents the fork from swinging evenly from side to side and there is some sort of vertical play as I believe the top pivot stone does not properly captures the fork. (I'm currently uploading a video to share)

While I've had trouble finding a proper service sheet, I found a post to a very similar one but I do not know where I would be able to find a proper pallet fork if I were to need one.

One more thing I have to mention is that I have not proceeded with doing any cleaning as show in the lessons as I've been wanting to get comfortable with the movement and so I'm not sure if that could be an issue with the pivot stones not allowing it to sit properly although I don't think that's the case.

 

I appreciate if you could offer any feedback on the issue. I seen this movement seems to be pretty good, but I was considering maybe finding a replacement Miyota or another orient on ebay or something.

 

Thank you.

The top pivot of the pallets has broken. So you need new pallets. Many members on here use https://www.cousinsuk.com/

What you call the oscillator. That is known as the balance complete. That whole balance has to be clean, any little hair or oil will cause the hairspring coils to stick togather and the timkeeping will be erratic.

    • H.Nathan and co where part of a group of companies owned by the Australian company called Hoffnung and Co their buisness was primarily based around the importing and sale of goods through catalogue they where importers among other things of sewing machines and parts, and Swiss and American watches and all forms of gold and silver jewellery and display cases for retail jewellers. They where a very large concern and supplied goods in Australia, New Zealand and Tasmania , Fiji and Honolulu and had huge warehouses across Australia. H.Nathan and Co was the company's London based subsiduary they where responsible for purchasing goods in Europe and America and arranging the importation to Australia they would have been responsible for the purchasing and importation of your watch, they would not have been the manufacturer of your watch as such but would have sourced them from manufacturers in Switzerland and stamped them with the company name, the earliest reference to Hoffnung and co I can Find is 1872. I think they would have been the Australian equivalent of Sear's Roebuck catalogue in America.
    • Can you post the link and I'll try and help you.
    • Yes that is correct. Looking at this photo you can see which strike side would operate the hammers. They would also need the springs to be the right force to run together, to compensate this the two hammers are lighter than the single one.
    • Some useful sites in case you havn,t visited so far. Julesborel.com Eternaltools.com OldSwissWatches.com Most recommended source is cousinesuk. Yes manufacturers recommend routine M/S replacement. Manual winding gives you an idea how well the spring feels, to say the least eliminates selfwinding mech form diagnostic guestimation. Joe  
    • Can anyone explain why there are 3 winding barrels to achieve this? Are there 2 separate striking trains?
