My watched Stopped for no reason

[thovis]

SO i woke up this morning and my watch had stopped. I got it about 4 days ago from a thrift store and it has been working FLAWLESSLY , not loss of time or anything. So i unscrewed the pin and gave it a wind, and it started back up. That was at 10am this morning and its been working fine ever since.

This is my first mechanical watch so im very ignorant to them, so is it possible the "self winding" part of it can be broken? and if it was would it had gotten 3-4 days out of a single wind?

Here is a link to the watch in question

Looking for info on a Vostok Watch I picked Up

I'd say you've done very well so far in fairness.

Amphibias have to be pre-wound just as you would any mechanical watch then the autowind rotor keeps it 'topped up' so to speak and it won't keep going purely on daily usage without that initial charge.

Any chance of a photo/ details of the model
Vostok autos have about 2 days reserve, Poljot 31..'s handwind 60+ hours.Curious about yours, but whatever many congrats

It had an initial wind, i gave it one when i got it. Pics are in the link in my first post.

Like i said this is the first time its done anything wrong since i wound it the first time i got it.

You can't 100% trust an unexpensive used watch... it may have some issues and any watchmaker will ask you more than the watch is worth. If the watch proves to be unreliable either you try to fix it or you throw it away or maybe sell it as "need repair/for parts" watch.
That's the story with used cheap watches: it's just a matter of luck.

The automatic mechanism of the tough and accurate Vostok 24xx is not the most efficient out there, in my opinion, and is dependent on how much you move it around, of course, so I look at it as a way to extend the run time not as a means of eliminating hand-winding. If you think about it the rotor has to swing around and transmit its power to a small gear that winds the mainspring so it has to be geared very low to overcome the resistance of the spring. That means it will take many rotations to advance the spring wind gear even a little bit.

Paul (schnurrp) is right, the 2416 has its own little eccentricities. A service (clean and oil) may solve the problem, but you may also have a bad movement. Easily fixed, as Zenitar (eBay) will sell you a brand new movement for $40 shipped. Then you're still only $45 in the watch and 'ahead of the game' still. Good luck with it!

What CCCP said. Or just give it a bit of a wind every day. No biggie.

I never pre-wind any auto watch that I own. I give it 5 winds to get the second hand going, set the time and let the auto winder do the rest. That's what it's there for. I never fully wind an automatic watch before I wear it. The Vostok can handle being hand wound every day but some other automatic movements out there like the ubiquitous ETA 2824-2 can't handle that.

In my experience, even when sitting behind a desk most of the day the autowinding system of the Vostok 2416b should be able to wind the watch from practically unwound to full power reserve in under a day.
