Why is it losing time?


Recommended Posts

I have this Vostok Europe K3 auto with hand winding circa 2007 which is losing 2 minutes per hour!! However, on the TG the results are looking pretty good as shown in the photo when dial up. Other positions are similar. If I leave the watch wound up and dial up it immediately starts losing time yet the readings contradict this.

Any thoughts what might be the problem please.

When setting the time it is very loose. Could that mean the canon opinion needs tightening?

Absolutely. That friction that you should feel is the clutch mechanism between the movement and the motion works. It slipping allows you to interfere to set the time.

So in effect the hands are slipping against the motion works? Tightening the cannon pinion is beyond me as I don't have the correct equipment at the present time.

A clean may also be necessary as Clockboy mentions.

Thanks for your imput.

What’s happening possibly is that the centre wheel is being driven normally by the movement, but the canon pinion (which slides over it) is not gripping it tightly enough. That’s what forms the slipping clutch. The canon pinion then drives the rest of the motion works.

I would estimate it would realistically take someone up to an hour to repair this if it is as trivial as I describe. 
 

It looks like the movement is running very strongly and I wouldn’t assume that it requires cleaning. Russian watches can be more crude than Swiss, but it looks like it’s probably running well in all likelihood, in my opinion.

If you have a dull nail clipper or would dull the balde of one by sand paper, it would work to tighten the canon pinion with.

Thanks for that. I will have to think about whether I do this or not!! I have some spare movements I could practice on which would be good experience and another new task to undertake. All good fun.

Thanks everyone.

    • people be honest.... Swatch is evil for the watchmakers and repairers, BUT not everything in watches from Switzerland is from the Swatch-Group. As far as i know, Selitta got sacked by Swatch as a Movement-Assembler for them and they started to produce Movements in their own Name with slight Modifications. As far as i know, they sell Parts to the Market for their Movements. In most cases, if a ETA-Movement fails, it is a valid Option to replace it with a Selitta Movement, which i consider the Solution for this Mess with the Swatch-Group...... I have no Connection to anybody at Selitta, but being a Swiss-Guy, i still like to have Swiss-Made Watches, but not from the Swatch-Group.   ok ? regards, Ernst
    • Just one more greedy act by Swatch. They started a number of years ago here in the US..cutting off supplies to watchmakers that could build complications that many Swatch houses couldn't even touch. Old school masters who had gone through some of the most prestigious houses in the world. Otto Frei has some statements on their page about it. I tell all my customers to avoid new Swiss watches like the plague,..unless they just want an older one in their collection that still has some parts out on the market, or they have really deep pockets and don't mind waiting months and paying through the nose to get it back. Plenty of others to choose from..IE Seiko,..or other non-swiss brands Even a number of Chinese brands are catching up with the Swiss,..and I think that in time, their actions will be their downfall
    • Yes. If that's not what you are experiencing...start looking for something rubbing. A 1st guess is that one of the hands is rubbing against the hole in the center of the dial. Especially if you now have lower amplitude in face up/ face down positions.
    • Once a movement has the dial and hands put back and it is recased, would you expect the assembled watch to have the same amplitude as when the movement is in a movement holder and is without hands and dial? Thanks
