Watch slows down when setting time

Canon pinion friction may be a bit tight, in some cases it will actually stop the watch. Some watchmakers back in the day considered it "right" when it'd stop the watch, it gave a sort of hack system.

Imagine if you grab the center wheel pivot going up through the dial, and twist anticlockwise. You're going against the power from the barrel. This is what the canon pinion is doing.

I’ll try. I was a bit disappointed as it is a nice watch.

Oh,  its as Nickelsilver said, canon pinion and perhaps minute train, with the one you on your bench.

I meant , some don't want to run regardless of the crown position, especially if the new piece has been sitting unused for couple of years.

Hi JD    Does it do the same when the hands are moved clockwise or only anti clockwise if so I second Nicklesilvers opinion on this one but also can see where Nucejoe is coming from as regards lubrication.

One other thing do the Russian manufacturers use the same oils and greases as the Swiss or are they on their own home produced oils and greases.  If so we may have quality issues here.

It's very normal; nearly every Vostok movement does that...... it's called the "poor-mans"-hack.

Nothing to worry about and certainly not a reason to send it back or "fix"-it. These are great watches and unbeatable with regards to Value/price ratio. In fact they beat nearly all, if not all Swiss watches as for sophistication & design for the price.

Just have a look at this link; what a fantastic piece of engineering for slightly over $40 !! ; https://forums.watchuseek.com/f54/vostok-2415-2416-self-winding-function-reversing-wheels-revised-5134701.html

So I took the movement apart and oiled under the cap jewels upper and lower and oiled all the normal areas. Got home tonight and now the amplitude is finally good.

Out of curiosity  did you record before and after amplitude numbers?

80 deg and 209 after oiling. It was a new movement.

First; 80 degrees can't be right.

Second; 209 is very low as well ...... are you sure you did set the lifting angle to 42 degrees?

Here are the new results with the 42 deg lift angle....very good now.76dc175cbd3dc899b84bac9b041804ca.jpg

If the lift angle is defaulted to 52 degrees  the amplitude  would be a false reading. I would  call your results  acceptable. Btw I love the amphibia  case.it is unequalled  at it's  price.

Maybe I go nuts like the rest of the world, but since when has a Vostok 2416b movement 21,600 BPH ?????

I'm guessing it's one of the other problems of whatever this is that's masquerading like a timing machine? According to the site below it's not a 21,600 bph watch.

Couldn't remember what mine was so I just put it on the Timegrapher.

It is indeed a 19,800BPH movement and with the lift angle set at 42 degrees it's returning a healthy 287 degrees of amplitude at full wind, it's on its original m/s and is currently 5 years down the line from it's last service (documented here).

@jdrichard there does seem to be something not quite right with some of the data that your timing setup is reporting, unless it's something other than a 2416b of course.

So Marc. You mentioned and I saw the thin metal spring at the bottom of the second hand wheel. What is that all about. My second hand actually fell off today, so I disassembled the watch, took of the rotor and put a white screwdriver in the hole that could be the bottom of the second hand and the spring that holds it in. Then I pressed the hand on again. Did I do this right?

      In the meantime whilst awaiting a better plan, please drop me a quick hello on my email.

      I looked at it like this, I've built a lot of stuff in my time, building structures and furniture,those are my creations and they will still be here way way after I'm gone. Traditional watchmakers felt the need to pass their knowledge on, ideas that they created . I assume with them as it is with me, leaving their mark on the earth, a way of being remembered. This creation of Mark's has brought thousands of people together to pass their knowledge around,  ideas that will continue to be used for lifetimes. Ideas that should continue to be procured. If for whatever reason the forum ceased to exist, not quite like Ranfft's, that didn't disappear but much less usable. Then that is sad, such a massive loss of communication between good people and a wealth of knowledge lost. There should be something in place for when that happens which could be next week, next year or in 10 years. Might not be a topical subject for a lot of folk or boardering on controversy, i did say i talk about stuff other people dont. But if you dont talk about it and something happens then you've lost it and you ain't gonna fix it .

      I've remained silent on this thread, and at the risk of upsetting everyone, the thing that worries me the most the the apparent absence of Mark. The moderators do a great job and the members also pitch in, and the site seems to run itself, but it is a concern for the future of this forum when the owner is absent for all intents and purposes. Like many of the comments above I would hate to log in one day and things be closed down as I rely on this site for ideas and knowledge and also cheer me up. maybe the Moderators could reach out to him, assuming he does not read this thread, and express our concerns and let us know the plans going forward? some kind of WRT ark

      That was the exact reason for me starting this thread watchie. Still we haven't worked out how the regulars are going to hook up if it goes tits up. I honestly think something should be arranged to stay in contact, we all help each other so much.

      Setting lever spring

      By Neverenoughwatches · Posted

      Yeah ive watched that a few times before,  i couldnt find my old school dividers to scribe it up 😅 Yep thats the guy i bought a roll from . Thanks Nicklesilver that answers that perfectly and more or less what i thought an experiment over time would prove . The jumper arm is quite thick along its length, i left it that way intentionally, i thought the original was probably very thin, i didnt see that it was already missing. Setting isn't particularly stiff as such just positive, i still need to take it out and polish where it mates with the stem release.
