Hi, it's possible to install a mainspring by hand, but you'd want to know what you're doing. Probably your best best is to buy a new mainspring and install that instead, as it will come pre-wound and ready to pop into the barrel. You might need to buy a barrel complete with mainspring ands arbor though, as it looks like these are manufactured to be replaced as a complete unit during servicing (same as Seiko 7xxx movements).

Otherwise you're going to want a mainspring winder with the correct arbor size and rotation direction for your spring, and ETA 2892 winder should be fit for purpose. There are cheap sets on Ali Express that have ETA 2892 winders included, or you might be able to get an individual one.

The winders themselves take some practise to get used to.

Thanks a lot, I`ll tell my boss to try this winder! But it`s very time consuming to order new barrel with springs all the time? Isn`t there any original winder for orient cal.46943 ?

Well boss said that he tried this 2892 winder and that didn`t help him? May be he did smth wrong ?

Heyo, you'll find that the Orient 46943 is most likely a clone of a more popular movement and/or uses parts that are virtually identical to other movements, so there has been no need to create tools specific to this movement.

In this case (according to my super quick research) the mainspring and barrel are identical to an ETA 2892, therefore the winder for that particular mainspring should be exactly what you need.

No guarantee I'm correct there though, just to be safe.

If he's put the mainspring into the winder the wrong way he's likely going to ruin it. What exactly went wrong? The direction and diamater of that winder should be correct for that particular mainspring (from what I've found).
 

 

Video for demonstration purposes only.... 

I'm wondering if he's using a pin/arbor vice so he can wind in the opposite direction that the supplied winder runs in? Might be something to consider, perhaps the 2892 winder does run counter to the direction you need.

Interesting wording you have up there? So you have a boss in watch repair?

Then unfortunately in watch repair we have to order lots of parts just depends upon the particular watch. Then typically winders for specific calibers only exist if they're extremely popular.

And found some information which indicates maybe there were variations for this watch? Plus I have a tech sheet attached down below.

Like while trying to wind the spring we were hearing a clicking sound and winding always stopped at this point. By the way if it`s not boring can you please tell how the spring can be ruined ? 

If you're hearing a clicking sound from your winder, the catch isn't engaged properly or you've got the mainspring backwards. You can risk the winder kinking/bending the mainspring particularly if you rotate the winder counter to the mainspring winding direction, as the catch can push the end of the mainspring and break it.

Well i tried today to bring the spring into the barrel by hands but i failed, anyways a new barrel have arrived so we`ll just replace the old one.

      Part swapper to part maker

      By Neverenoughwatches · Posted

      Thanks Rich, its really not that difficult to make them, simple ones anyway. Cousins didn't have the part though i could find it on ebay at 6.50. I figure i earned about £1.50/ hr . It paid for the diamond files i bought.

      How to remove shock settings from Smiths 512 movement

      By mikepilk · Posted

      If you look at this thread, you can see I had exactly the same problems with balance springs with 2 prongs on a Smiths 627. The slots in the chaton were not big enough to get the ends of the spring out. I had to bend them to get them out and back in. Not ideal. I don't fancy having to do it again as they could easily break, and where would you find replacements? I didn't come across the 3 prong type.

      Breguet Exhibition at London Science Museum

      By mikepilk · Posted

      I visited the Breguet Exhibition today. https://www.sciencemuseum.org.uk/about-us/press-office/rare-timepieces-unveiled-new-display-science-museum The Science Museum now holds the collection of "The Worshipful Company of Clockmakers" - "The collection includes more than 600 watches, 90 clocks, 30 marine chronometers and a number of fine sundials and examples of hand engraving, mapping the history of innovation in watch and clock making in London from 1600 to the present day." It's well worth a visit. They have some amazing pieces by the likes of Harrison, Breguet, Tompion etc . I've visited twice before but decided to go and see the Breguet Exhibition. Maybe I was expecting too much, as on reflection, "More than 20 extraordinary timepieces designed by inventor and watchmaker Abraham-Louis Breguet " isn't going to take up that much space. In reality, it's just one cabinet. But, Oh those watches, stunning 🤩 , e.g. (No 1297 was made for George III and is valued about £1m)   I tried a couple of pics, but with subdued lighting and taking through glass, they aren't good. I like thin hands on a watch - how about these (I think this is a split second chrono)   And this one, with all it's complications, is only 10mm thick !   What I found very interesting were a few very old machines for making watch parts, like this 17th Century gear cutter. The disc below has concentric rings with holes in, so that is can be set to cut varying teeth numbers.

      How to remove shock settings from Smiths 512 movement

      By RobS · Posted

      Firstly sorry for poor image quality I only have an iPhone for photos.    Im working on a 512 movement and I’ve had some trouble with the “jewels”. I’ve got the metal one out, but when I tried to put it back the three sides of the spring seem to need pressing all at once to fit it as there are three “holes”. I get two corners in but as I go for the third the first two pop out! Constantly I’ve lost the spring. I’ve done the similar ones on seiko movements without trouble. Assuming I find it/a replacement, what am I missing!   on the other side with the only ruby in the movement is a setting with no “gap”at all. How do I get the spring out, and of course get it back in!    What am I missing!    thanks in advance.    Rob

      Links like that are the reason I routinely donate to the Internet Archive - they are the last safe house for a tremendous amount of useful info that is otherwise lost.
