Received a watch today fitted with an eta 954.111calibre quartz movement .

I fitted a new Renata 399 battery but it is running really erratically , it goes along fine but then visibly speeds up .
Would it be something that a service might cure or is there something more to it.

As i say it's not running fast all the time but then it just it just seems to have a funny turn.

It was running better i think with the case back off , so i did put a small piece of plastic over the battery just incase it was shorting or something but that doesn't seem to of made any difference.

Any thoughts most appreciated guys TIA Andy

Hi Andy,

 

Sometimes the hands touch each other at certain points if they are not completely "horizontal"/"parallel", or the dial is pushing the hands up (became loose), or the hands are touching the crystal for some reason...those are the easy fix options: redo/press/push down/etc the hands or/and the dial. Otherwise I'd look for some worn or broken gear, bent pivot if the problem is cyclic. Electrical issues may happen with a bad connection/loose solder. IMHO.

 

Cheers,

 

Bob

Recently serviced a 954.111 movement. There aren't that many gears in this movement? Maybe it could be some thing with the stepping motor. You could lift the rotor out and clean it with rodico. I haven't finished my watch as i am having a problem with the date ring? It's worn and won't shift properly? Saving the movement though. As they are rare and hard to find this days.

Thanks guys.

Well after gaining around 9 mins in a couple of hours it didn't gain anymore overnight , so reset this morning and so far it is keeping good time , so it appears to of settled down.

Will keep an eye on how things go , but i think whilst it is running ok i'm inclined to leave it .

cheers Andy

      Generic screws for unknown movements

      By Chief · Posted

      So I found what I believe is the setting lever screw! Am I right in thinking the screw next to the click is the correct one for the setting lever? However if it is, it doesn't fit in the hole which I believe is for it! I can get the lever to sit nicely on the stem and line up with a hole, but the screw only goes as far as the shoulder and stops. It's as though the hole is too small! The dial side has been disassembled by the way, the other wheels are in my tray

      Gilding after silver soldering

      By AlanB · Posted

      When faced with say a pocket watch bridge which is cracked, silver soldering to repair is often the only option (hopefully someone wasn't there before hand with soft solder). I can generally do this succesfully and tidily with a small torch and miniscule pieces of silver solder, but on parts which were mercury amalgam gilded the heat can have have a deleterious effect on the finish.   I keep wondering if there's a good way to refinish these - and despite having the needful items would rather avoid using the mercury process.   In the past for electronic work I've gold plated PCBs but this involved gold potassium cyanide solution, which also doesn't realy belong at home. I've read that there are now safer alternatives but couldn't find more detail (and importantly how similar are the results to amalgam gilding, since I wouldn't want to refinish the whole watch). Pointers would be very welcome (and yes, I know solutions containing gold won't be cheap!) Alan

      Ok so with the great answers for my previous question may I ask what these two attachments are used for. The one with the red knob is I assume used for hand setting the seconds hand? Jon

      Roamer Searock Crystal problem

      By Zedster · Posted

      According to Cousins site I need to look at document G22 as I think I need an ATGB at 304 but I cant find this size in G22 doc. The last thing I want to do is order the wrong one😳  Unless I cant see the wood for the trees 😆 I could be looking at the wrong style, I assume its classed as Round plastic Armed  https://www.cousinsuk.com/product/wide-ring-gold-atgb
