Okay, I’ve sussed that. Looks like a balance spring problem. Any advice on stripping this thing down?IMG_2359.JPG

You now need to remove it from the case. That inside ring should just pull our, unscrew the feet and the top and push from the front. Once removed can you show me a photo around the spring to include the click, as some of these types do not have a normal click spring and click.

That is just what I expected to see. You cannot un-wind the springs in these movements. If you try and lift that circle shape which is the click, you will distort it and it will not wind up. Can you un pin the balance and take it out and show me please. It looks like the h/spring is damaged, if that is it is you might be able to repair in, oil the movement and see how it goes.

Yes, I need a picture of a good balance spring.
If I could get the face off, I would just dunk it in cleaner and oil it as is. How does the face come off?IMG_2377.JPGIMG_2378.JPGIMG_2379.JPGIMG_2362.JPG

Hi you need to take the hand off first to get the face off, have you got a hand puller??

I use levers, but I wasn't sure if that one just pulled off.

The face seems to be fixed to the backplate, somewhere near the twelve o'clock area.

Don't remove that hand. That is the alarm hand, it is fixed to the alarm wheel behind the dial. The movement should come away by ether pins or screws or both. Depending on your skills that h/spring can be sorted.

Thanks. That's what I thought about the alarm hand. I just can't see how the face is fitted to the backplate. I can't see any screws or pins. 

The dial is free all the way round, except for a point in the twelve o'clock position, midway between the centre and the edge of the face. Could it just be double sided tape or something? although, it doesn't feel like it.

I can sort the spring out, no problem. I've found a picture of how it should look.

Yes it would.

Do you think I can separate the two parts without stripping the top half first?

If I run the springs down, how would I go about removing them and re-installing after cleaning?

I do not recommend this. You could undo the plates by a little and remove the pallets. Make sure to add oil to all parts that will run. Be very careful not to bend any pivots (its soft metal) the train will run down, you can put a finger on the train to ease the run down. When it is down you can take it apart and clean. You should be able to remove both springs from there arbors. Take note of how and where the springs are attached, they should be open loop and attached to the pillars. When putting it back together make sure, the springs are attached to their arbors. So the movement is together and tightened down, wind the springs up and as you go you should be able to attach the open part of the spring over their proper pillars.

Pick a spot where to start, the higest part,

Take note of how and where the springs are attached, they should be open loop and attached to the pillars. When putting it back together make sure, the springs are attached to their arbors. So the movement is together and tightened down, wind the springs up and as you go you should be able to attach the open part of the spring over their proper pillars.

You will just have move the parts into their holes. You can screw down the nuts a little by little, to hold things in place, not to tight or you could damage pivots.

Thanks for everyone's help, especially oldhippy. I managed to get it all back together again. Manipulated the balance spring back into some kind of spring shape, and it's running very nice now.

Most important, I learnt a lot for the next one.

      Rolex 645: shock protection cleaning and pivot wear

      By GPrideaux · Posted

      1. I think the pivots look pretty good and I wouldn't worry about wear. 2. Yes, I think the hole jewels should come out for cleaning, complete with their spring setting. I don't have experience with Rolex but I've seen this spring type setting in another movement. They may be stuck in with old dried oil. 3. Yes, I think the overcoil is out of shape.

      ETA 2472 - how to tackle this crown and stem?

      By Michalzeszen · Posted

      Yes, I'm looking at this option. I have a good friend from childhood who happens to be a goldsmith, and he would certainly be able to tackle the second hole to my specifications. I usually avoid this path because, since he deals with gold pieces, every time he stops to help me with "frugal" parts, he is objectively losing money. I agree with you. Even though I couldn't justify paying this much for the set (they only sell the whole set or the sole case tube), I understand the price tag. The trouble with this particular stem set is that the most common use case for it is the Technos Skydiver, a watch whose price certainly justifies 220 USD for a brand-new stem set.   I have messaged them only on the surface, without specifying my needs. They already stated that they don't sell the single female part, only the full set. What I still don't get is the need for a second hole. Is it supposed to be some sort of regulation, meaning that I can fit the head of the male part in any of the two holes to adjust the pressure of the spring? Does this mean that a single-hole female part has a chance to work with my setup? I'll later test this hypothesis while continuing the assembly of the movement. Some photos are attached. Can you judge this bracelet? It was dirt cheap (4 USD), genuine leather, wife's choice. I have just realized my dial is upside down. lol

      Royama watch with Grilamid Base

      By Juleswatch · Posted

      Hello from chilly Brazil! I just bought a couple of watches and this watch came with them. While perhaps not worth much I'd like to try to find out something about it. Googling comes up with with the name Gerald Genta, and I see from internet searches he's made some nice designs (perhaps an understatement)! Also some cartoon designs but I can't find anything like this anywhere, so most likely not his!  Googling Royama I see that some famous people liked his watches and also the Royama watches. Two questions; 1. Can anybody tell me anything about this watch and its background? 2. How to get the base off to let down the main spring which is fully wound. I gently tried prying it but nothing, I see there is a button but have no idea if it is functional for removing the back or anything else. Screwed back maybe? I really don't want to break the back or the watch with too much pressure and haven't looked up the properties of Grilamid!   Probably not much of a watch but it peaked my curiosity and I hope somebody might be able to help? The auctioneer sold it as a psychedelic acrylic 1960/70 Royama watch overwound! All the best...Jules
