Hi all,

I've been having trouble with a vostok amphibia I recently bought. I've got a number of vostoks and they've been pretty much alright. This one though was running fast right from the off. It was gaining about 90 seconds every hour. I should of sent it back to Meranom but I couldn't be bothered with the hassle of packaging it back up and sending it back and then the long wait. Plus it's seventy quid watch, might of been different if it was a rolex or something like that.

I decided to open it up and have a look. I'd already stuck it on a time grapher app (I know they're not as accurate as the real thing) and it had picked up something wasn't right. As soon as I looked in I could see the hair spring wasn't looking right. It was bunched up, compressed on one side. Eventually I noticed one of the outer coils had hooked its self around the beat error adjusment stem. I carefully teased it off and the watch sprang back into normal life. I've worn it on and off the last few weeks and the watch has been exceptionally good. It's kept within about two seconds a day and then yesterday it started playing up again. wipped the back off and it was the same fault. Teased it off again and alls back to normal.

Has anyone had an issue like this before? I really don't want to start messing about with hairsprings as to be honest that could be beyond my skill set. I'm thinking maybe of getting a new balance unless there might be a fix that I could perhaps do.

Any help much appreciated.

hi GB pretty new and I'm guessing here-have you checked for magnetism, dust, nicks or dents you might have missed? is it an overcoil hairspring or flat? is it concentric? check that regulator pins are not bent, loose or missing and their gap is correct and that the spring is running thru them, centered. are you able to regulate it? hairsprings are a whole different animal and skill unto itself. I shake my head even as I type this...I try to avoid them if i can and only tinker with junk ones, you know? good luck!

I actually thought magnetism at first and checked it passing a compass over it but it was ok. I demagnetised it anyway. 

It definitely looks flat when you look edge on. I'll check again the things you mentioned and see if I spot anything. I've got a proper time grapher arriving this week so that might help pinpoint some things.

Thanks.

BTW I just picked up a "gently used" Vostok Amphib and I love it. first one. 75 bucks and it came with this awesome stainless mesh band. mesh bands to me are hair assassins to my wrists but this one not a problem at all.

This is odd. The only time I have ever seen anything like a watch suddenly  gaining time was from  over oiling. The lubricant migrates to the hairspring and the coils stick together  increasing the rate. Suggest that you remove the whole balance  cock and clean  it with naphtha.

thinking that also, was wondering what it might be getting stuck or hung up on. see what the OP says...i would think he would have seen any gunk right away the first time he debugged it but he didn't say anything....

I bought a brand new monster snowblower, ready to challenge mother nature with her mood swings and heavy snow. 2nd time I tried it thing sounded like an old Model A with a bad cold...couldn't for the life of me figure it out. opened the air cleaner cover and low and behold Ratatouille and his 3 friends took up residence in the carb. Moral to the story:

I think he's got mice in his watch lol. gremlins. I hope he gets em. they're everywhere.

But would that cause one of the coils to get caught on the beat error post. It's twice it's done it now but apart from that it runs within a couple of second a day. I think you might right and remove the whole balance and get a proper look at it.

Been using a timegrapher app up till now. It's ok but a bit hit and miss. Hopefully this week the proper one arrives.

which one? the usual suspect that is out there? the 1000? thats the one I use. perfect for my little operation. and, they've dropped in price since I bought mine in the spring.

 The fault is very likely to be found, if you are set up to show a close up vid of coil oscilating.

hairspring loose in the stud?

well Paul, sounds like you've got some tinkering ahead of you. now that you've got us all lathered up about it you'll have to let us know what you find. keep us updated.

Hi this type of problem can occur if the watch is worn during golf or any other activity where the arm incurs violent movement suggest   keeping it in the pocket for a week and see if it happens then, If it still occurs we need to re think.

It it happens again I'll try and video the balance or at least get some photos.

Coil needs to expand as far as stud to get stuck behind it, if unlevel, outer circle of coil can pass beneath the stud, that much expansion usually occurs at high amplitude.

Otherwise it can be loose stud or coil pushed to the side that stud is. You might even see outer circle of the coil not concentric with next inner circle.

A visual inspection may suffice to see what happening but a vid tops other approaches of inspection.

The coils on the left of center seem to be compressing much more than those on the right of center.  

The terminal curve seems to be running straight and true (as far as I can tell from this angle) between the pins. 

I don’t think it’s gunk; I think the spring is running oddly. Based on the way the reflections look, it’s as if it’s rocking in and out of flat as well, which I suppose could cause the terminal coil to jump out of the pins under certain conditions.  

Another video looking at the coil from the side would be good. This is a candidate for hard core spring manipulation. 

Last thought- is it possible the stud is lose somehow? Maybe the end of the spring rocking in the stud?

Further to the above, coil as said is too close to stud, both 145degree angles at the bend should be widened by 20 degrees.

The problem with HS manipulate is you affect nearly all aspects( centricity, flatness, levelness  .....) as soon as you tweeze it specially at the bend, so you would need to simulataneously check and readjust all said aspects.

If you don't feel skilled at this, I suggest letting someone who does do it.

Even a new balance complete requires final touches when installed.

Regards joe

I opened up two other amphibias I've got and the hairspring on both those compress more to the rear so I'm guessing this one is working as it should.  I've checked edge on and it's perfectly flat. I've also checked all things are tight and nothing is moving that shouldn't. I'm going to wear it non stop for the next few days and see if the outer coil jumps again onto the beat error post. If it does I'll post another vid and pics. Thanks for all your suggestions and help.

    • The unfortunate problem of the three jar cleaning machine. At least I assume it's a three jar machine. Classically with three jar machine the first is a cleaner and the second to be a rinse of the same type. Cleaning is a interesting process and it's not exactly cleaning and rinsed the entire procedure is cleaning. The cleaner is supposed to have chemicals to put things in the solution and things to make things right and shiny. The rinse continues to put things in solution and reduces the concentration of things in the fluid on the plates. Ideally you should have two rinses not one and alcohol. If you look at the modern cleaning machines you find typically now they will have a minimum of four jars or whatever. Often times the last one will have alcohol because depending upon where you live the rinse itself may not evaporate. So you have a final rinse of alcohol just to rinse off the rinse. Then the only thing I've ever seen on baskets would be this quoted below from something Omega has. But they are assuming that you have genuine Elma baskets and not a machine made in India from unknown materials. Although a lot of people are using the baskets from India I just don't know enough about them. Personally I've see in the baskets for other machines especially the holder which would be as it's implied below nickel plated where the plating wears off and eventually the brass will be etched away from the chemicals in the cleaning product. One thing I didn't see you mention was how long in the each of the baths? Usually for the cleaning products that make things bright and shiny. Time-limited approximately 4 minutes works really well. The rinses of less of concern it depends upon how much the cleaning fluid is dissolved in it though. You can download the specifications the cleaning products I like they have recommended times the final alcohol rinse is supposed to be relatively short as any time we mention alcohol and watches people get excited over dissolving the shellac. But typically with isopropyl alcohol it takes a little while longer and I've even used alcohol which I know dissolves shellac but I was just using it to rinse off the rinse so it was never a problem.  
    • I think i am done. I was working withe two pieces, one was 316 SS and the other 304 SS. The starting material for 304 was thinner, so I opted for finishing it. Since I only have images of one of these watches, I cannot know the exact dimensions. The owner is not critical...just wants a working solution. I think this is it. It was quite the challenge to turn the inside  locking rim. An inside angle cut. Had to be damn close in order to have a snap fit. Frankly I think I just got lucky. Sometimes lucky is better than smart! The inside edge that interfaces with the crystal is an interference fit. This was on purpose in case my locking-edge cut was overshot...then the bezel and crystal would work together to stay put. Tens of hours working on this, and I learned a lot!    
    • I'm using: 2.5L Elma WF Pro – New Formula for the main cleaning 2.5L Elma Suprol Pro – New Formula for the first rinse Isopropanol Alcohol IPA 99.99% for the final rinse So far, all fresh fluids. I was also under the impression they shouldn’t cause rust, so I’m wondering if maybe the damage was already there and is just progressing now. Because my baskets came with the machine when I bought it pre-owned, I’m not sure if they’re original Elma or not. That’s exactly why I’m hesitant to buy a new set—I don’t want to end up with lower quality clones again if that’s what these are.
    • It looks like the tube (pipe) for the hour counter hand pulled out of the hand and is still on the hour counter wheel. You can pry it off with small levers.
    • Hi @mcoulton, I was looking at the manual and my own fotos to understand you problem. I wasn't sure I follow. But to be sure: when you write "Hour Hammer Counter Wheel is pinned to the Calendar Bridge", are you saying that it's stuck to the bridge? It shouldn't (it should come off easily, actually -- worst case, the pivot is bent). You'd install the wheel onto the main plate, position the hammers/locks and then put the calendar bridge. I found this video quite good, time stamp added to the assembly of the hour counting wheel:
