Accutron Swiss Quartz W/ETA Movement Replacement


Recommended Posts

I've owned this "Accutron" branded chronograph for quite a few years.  It's had numerous battery replacements.  Last years, I the 1/100 hand stopped resetting (the other hands reset fine).

Last month, it stopped completely and I thought that the battery was dead. I  put in a new battery and it is still dead in the water.

This blog entry about the watch says is uses the ETA 251-282 movement

From what I find, that movement does not have a date.

Some pictures of my movement, which appears to read 251-292

I've found two similar movements:

And

http://www.startimesupply.com/merchant2/merchant.mvc?Screen=PROD&Product_Code=ETA251294-4A&Category_Code=09-Movements

Will either work?

Star Time Supply won't sell to a hobbyist, is there another retailer that sells this movement?

I found this one on Ebay, sold by a Greece seller.  It does have the date at 4 O'clock:

I know the watch doesn't have great monetary value, but it was gift from my wife, so it has sentimental value

Any advice is appreciated!

Just so you know, your battery clamp is in the wrong way. Shouldn't actually effect it, but I have to say it. 

I'll let someone else decide if any of those would work as alternatives but I'm assuming straight off you'll find something different that is some sort of problem. I don't want that responsibility when you'd be paying so much. :D

Hello,

I have an account with Star time. The watch movement you've mentioned is the correct one, and if you want the date at 4 o'clock then you click on the other link to specify the 4s date wheel:

As you can see, it's not cheap, so maybe the movement from Greece would be a better deal if you factor in shipping. I would be willing to order it for you if you decide that's the best choice.

Thanks for tracking that down.  So that looks to be a very good Quartz movement?  I'd be Ok making that investment.  But, I really struggled in working on my Hamilton Quartz chrono this weekend, I don't think that I can remove the chronograph hands.    I just sent you a PM

I did flip that battery hold down, but no dice.  The stopwatch flyhand moves and resets, but the secondhand doesn't move.

Well, thanks to some help from a forum member, the Accutron is back in business.  That ETA movement was indeed the correct one.  The sweep second hand didn't fit, so the hand that came with the new movement was painted to match.  Everything works perfectly!

I definitely didn't baby this watch and it's had its share of abuse, I decided that the case needed a polish, and I'll be sure to treat it a bit more carefully moving forward.

Thanks for the help!

    • As with every skill it watchmaking, it takes practice. Notice at the top of the document it says, "Practical work - 40 hours".  I can get the balance wheels 'close enough' to flat, but never seem to get them perfect. Same with gear wheels. Guess I need more practice.
    • Has it got a beat adjustment on the platform or is it a fixed hairspring? in short what you are looking at to get it just about in beat is to get the roller jewel sitting dead centre between the banking pins. So remove the platform and take of the pallet fork and escape wheel to give you clear line of site, sit the platform with the balance in place and with it level look between the banking pins and see if the roller jewel is sitting between them, if it is nice and central its there or there abouts in beat, if its not the the position of the pinned end of the hairspring needs to be adjusted to move the roller jewel into the correct position, thats why I asked if it has an adjustment on the platform or not, if it has its an easier job. 
    • I've managed to adjust it. I'm going to try and explain it as well as I can with my limited horology knowledge but I hope it helps someone in the future. There is a cam to the right of the front plate as shown in the picture. As the clock ticks along, the pin indicated in the gear comes around and slots into one of the silencer cam gaps, turning the cam. The pin completes a full rotation in 2 hours. To adjust the cam to start at the right time set the clock to just before 7. I did 6:45. Then I turned the silencer cam anticlockwise, which spins freely, until it pushed the silencer lever up and was placed just before the drop. Just before the 7AM indicated in the picture. All I then had to do was progress the hands to 7-7:15which made the pin slot into the silencer cam gap and turn the cam so the lever comes down again, unsilencing the clock. That was it. If anyone comes across this issue again I'd be happy to assist. Thanks again to everyone that helped. Hey Transporter! Thanks a lot for the reply. That was a really good explanation and I'm sure it would have made my troubleshooting a lot less painful haha. I'm sure someone will find it useful in the future. Thank you again for taking the time to try and help me out with this.
    • Now I'm completely confused, it would appear that the epilame  is oleophobic  as @Marc states: This oleophobic  behavior can be seen as beading of the droplet (as above) which stops the oil spreading which is supported by what we observe on treated/untreated cap stones (for example), but as @VWatchie states this should make the drops more mobile and is supported by the literature:   A review on control of droplet motion based on wettability modulation principles design strategies recent progress and applications.pdf   However the hole point is that we have less mobile oil so an oleophobic  would see to be the opposite of what we want. In fact this beading and high mobility are desirable properties in things like smart phone covers, see below.  I am fairly sure that epilame doesn't make the droplets more mobile, so maybe its a strange coating with dual properties that are both oleophobic (beading) and cohesive/adhesive resulting in low mobility?? This may explain the high price??  
    • The description there is exactly how it's done, and it's very well written!
