Another Buzzing Accutron - Thanks Geo!


Lee

Recommended Posts

After Geo started the time to hum topichttp://www.watchrepairtalk.com/topic/426-time-to-hum-again/?hl=accutron#entry2872 I had to have one!

 

I brought this little number yesterday & it arrived this morning.

these are a really pleasing watch, prices are VERY reasonable & there's loads of history available about them online & the buzz from the tuning folk is lovely to listen to. I'm amazed these aren't dearer to buy.

 

Anyway mines a 1969 (year I was born) Accutron  spaceview,  with the Swiss 770 case, wide gray chapter rings & orange second hand. the wider chapter ring & orange second hand tie in with it being a later 1969 as they changed these details due to falling sales against the increasingly popular 218 models. also my case back is missing the mention of water resistance which was taken off later in the 1969 year so its quite easy to date.

ive put batteries in them over the years but never seen a spaceview until Geos topic. I just liked the look of it & when I realised how reasonable the prices are I kept my eye open. I also have a thing about being left handed & crowns, it bugs me that watches are rarely available as a leftie. so this fits the bill as the adjustments made from the case back, that I like! its a watch that ticks a lot of boxes for me!

Hi Lee, that's a really nice looking example that you have managed to acquire. I'm glad that posting a picture has ended up with you getting one. Enjoy!

That's me just back from holiday and I had my Omega hummer with me for a change. A word of warning though, if you leave it on a bedside cabinet that is empty, the cabinet acts as a sound board and you will end up with an amplified 300 htz keeping you off your sleep. It took a while before I worked out where the noise was coming from!

in the first couple of days this watch was gaining a minute a day, so I brought an Accucell-1 from the small battery company. These are nicely made, they have a resistor packed in somehow to reduce the voltage. It broke my heart having to pay £7.80 for a single battery! but its now keeping time to the second!

Hi,

  I just read this question about taking the accucell apart. I have done that and it will work for several battery changes. You have to be careful in that there are two copper plates inside the plastic ring and they are attached to the battery with what appears to be hot melt glue. You do not want to damage the small diode that is between the plates. You will need to remove these plates from the battery then reinstall them inside the spacer ring along with new battery. The new battery should hold the plates in place inside spacer without using any glue. I have managed to reuse them 3-4 times before they failed. The good thing about trying this is the battery will be dead when you start to work on it so you have nothing to lose. One other thing you will need to watch out for is that the battery is not too thick when you finish. Make sure you use proper battery and everything seats properly, otherwise it could be thick and damage the plastic plates of the movement.

Have you tried taking an old accucell apart for a battery change? or brought a new one each time?

I must have missed this.

I have not tried to re-use the accucell case, but having just read Charles' post, I'll probably give it a go.

Thanks for the detailed explanation Charles!

Just a few observations and please pardon me if its stuff you already know.

 

I have a few Accucell-1 batteries and when I started messing around with Accutrons the main thing I had my attention drawn to was the battery choices and Voltage which is 1.35 as opposed to the Renata 387 which is 1.55.  There is a handy table on another site:

 

Model Mercury type Silver Oxide type 214 387 387S, 394**, SR936SW** Accucell 1 218 343 344, 350. SR1136SW Accucell 1 219 343 344, 350, SR1136SW Accucell 1 2210 388 329, SR731SW*** Accucell 2 230 343 344, 350. SR1136SW Accucell 1 224 343 344, SR1136SW Accucell 1 ESA 9162/4 343 344, 350, SR1136SW ESA 9210 343 344, 350, SR1136SW Omega 1220 343 344, SR1136SW Omega 1300 313 357, SR44 Omega 1301, 1302 343 344, 350, SR1136SW

***Not a perfect fit, but there is no direct equivalent to the 388.
** These are not supplied with the little plastic spacer. Re-use the spacer from your old 387 mercury cell.

 

You note that for the 218 they advocate use of Accucell and also the 344/SR1136S but the main difference between the batteries is the Voltage ie 1.35 as opposed to 1.55. The use of either battery on a 218 is possible (if not recommended) but if the watch is normally phased for 1.35 and if you then use a 1.55 then it can lead to double indexing on the index wheel.  Some repairers re-phase the 218 to use standard Renata 1.55 cells.  I suppose what I am saying is replace like for like as if it has been re phased and you put an accucell in then it could lead to a problem.  I have a few movements that are humming nicely but even though they are only movements without cases I always check them out with an accucell.

The 214 has a similar sort of choice, if you buy a Renata, the 387 is shown on the package and it has the black plastic spacer disk on it but the positive side of the battery shows the number 394 and it is 1.55v. 

 

I have just returned my Accutron (bought in May) to the dealer I bought it off because gold on the case and crown was literally rubbing off.  It looked great when I got it but it had obviously been brush plated to give it a thin gold coat.  Give the guy his due and the benefit of the doubt he appeared quite surprised when he wrote back to me after inspecting it and agreed that it was not acceptable.  He offered to source a replacement case which he sent pictures of and I have accepted.  It makes a nice change to get customer service - I had expected a bit of a struggle.

 

Anyway its nice to see the hummers getting a bit of attention.  Lee put me on to the Stereo Microscope which has made a great difference for examination of the index wheels.  They are not easy watches but definitely have less bits inside that the Mechanical ones :D

 

Cheers,

Lee that is a super-looking watch and the strap is sharp too! Besides Omega, Bulova is one maker that I keep close to me because I love their history and designs. My Omega Constellation f300Hz chronometer (198.0022) uses energizer 344/350 with no problempost-328-0-08866900-1415163273_thumb.jpg

 

But this is a different movement than the 2xx series by Bulova and was modified under license by Omega. A few other watch companies used this hummer topower in their watches too such as Zenith, IWC, Movado, Longines, and I think Certina. They all used a variant of the ESA movement 9162 which is basiclaly what is inside my watch--a Omega 1250 caliber. I have a watch that  takes the best of both companies. By the way, I had my watch serviced here in New York by Ernie Goldman of StarFindings (its on the web) down on Canal St. and he only does Accutrons and is a graduate of the Bulova Schook etc., etc. He told me a lot of baloney all the time about batteries and stripped index wheels and such and not to believe it because this movement is actually very robust. I mentioned this because Ernie is a very forthcoming person and he's been in the business a long time![attachment I do agree with Vichy when he says replace like for like and don't just go and buy the accucell replacement. My watch runs as good as any watch in my collection--In fact I use it as a reference to set the others.

Here it is again showing off

    • I was going to say, but texting can be difficult due to a lack of nuance, that maybe staying on here could be a good thing.  You do need a  distraction, yes mum comes first but you need some time for yourself.  I hope this has come across as intended. 
    • Hello forum, i have some things i would like to say today if thats ok. Being here is something of a sanctuary for me, talking about something that i love doing with folk that i have become fond of ( yes quite surprisingly under all that craziness and verbal brawn lays a soft heart of gold 🙂 ). I imagine that the same can be said by many of you , a certain number of us are here daily both learning and offering any advice that we are able to. Quoting our experiences both successful and failures for others to learn from. For me at the moment just making this post is a distraction from my current bubble but also from the world around me for various reasons.  Its a place not just for teaching and learning but to make others laugh and smile and be part of a community. I would even go so far as to say we are a team, supporting and encouraging each other when needed and when we are down, my own situation with my mum being a perfect example of everyone's kindness. Thats the soppy bit out of the way 🙂. So my mum has been moved to a brand new facility after making amazing progress with her speech and word recognition in hospital ( poor mum has had to suffer my company and my teaching to the full extent of her visiting hours barring one day off for me that my sister insisted upon ) her consultant calls my mum his medical miracle 🙂, and will be starting her intensive speech rehab today after her initial assessment. Things I've learned about having a stroke, and I'd really like everyone to take note of the causes and outcomes of having one. Please do your own research I am a joiner and not a doctor 🙂, i just want to make everyone aware and just get checked out if you notice anything in yourself that you are unsure about, any risk of having one can be reduced with either medical intervention or/and a change of lifestyle ( which would be my own preference in an attempt to limit my risk, something i have now noticed in myself ). I do know a few of you here have experience but this is what i have become aware of and how it has affected my mum and me. First i want to touch on the effects of a stroke, not only to the sufferer but to the whole family, we all know how dementia affects lives. A stroke effecting language is almost instant non aggressive dementia. Like being in a foreign country where you can no longer read, write or speak to someone without some form of very basic sign language gesturing ( when annoyed i think everyone understands the middle finger ). But a stroke can affect movement ( fortunately my mum is virtually unaffected with her mobility, the nurses can't believe she is 87 and just had a stroke, she's like bloody Supergran, in fact she is a great great grandmother to 2 toddlers ) . Improvement after a stroke carries on for years afterwards, but from what i understand and now believe after being with my mum almost every day since it happened for 7 hours a day, language rehab should be started as soon as possible when the patient is out of danger and physically able. The brain is ready and set to go and rewire itself soon after injury, in a similar ready state to young children ( when we say kids brains absorb information like a sponge, thats pretty much true in early stroke patients) After the first few weeks maybe a couple of months things start to slow down and lesser progression carries on for the years following . After a day she could manage only one word, which was my cue to get on her back and start pushing her progress. Day two i wanted to see how capable she was so i had her writing on a whiteboard ( it wasn't great tbh ) . Day 3 and until she left the hospital most time with her was spent on picture/word recognition on my laptop, picture books, some writing and teaching her to play cards again ( i refrained from gambling for real money, though i was tempted, as I'm  pretty good at poker , she has a few bob and i have space for another watchmakers lathe in my watchroom 🙂 ) Now i suppose i have to back off as the rehab place is fairly intense focused and visiting times are crap as they interfere with all the physio and rehab going on . So i only have 2 hours max a day with her sometimes only 1 if her grandkids want to visit, but she is in good hands and i know she will get as much help as she needs , and as difficult as it is to admit i probably need a bit of a break and distract myself. I'll end this post for now but i want to come back and talk about what caused this and hopefully remind some of you to think about how we live , what to do in the event of a stroke and how we can lower our risk. I'm not a pussy by any means and very little frightens me, but seeing this first hand has put the fear of god into me if i ever had to suffer the outcome of a stroke. My mum is a tough old cookie and i imagine i will be just as tough, but watching the frustration on her face when trying to communicate completely tore my heart into pieces.  Please dont let this happen to you, do everything you can to avoid it, I'll come back soon to talk more about as long as everyone is ok with it, take care for now x
    • The fact that you have witnessed coils of the hairspring clinging or sticking together explains why the watch is running so fast.  If you reduce the length of a hairspring, the watch will run faster. When hairspring coils stick or cling together, this effectively reduces the active length of the hairspring, so the watch runs fast.  As nevenbekriev has said, the most likely culprit here is oil or other contamination on the hairspring causing coils to stick together. Cleaning the hairspring as he describes will solve the problem. Occasionally the contamination causing the hairspring coils to stick can be very stubborn to remove, in which case I suggest ultrasonic cleaning in acetone, naphtha or a commercial watch cleaning solution. Magnetism can also cause coils of the hairspring to stick together, if the hairspring is made of an alloy that can be magnetised. Finally, your watch has what is called a pin pallet escapement. They are considered to be less refined, but quite rugged compared to a traditional Swiss lever escapement. They are quite forgiving. They do require lubrication, if you haven’t done so already, find instructions for lubrication of these escapements to get optimal performance from this watch. Hope this helps, Mark
    • Murks, In theory, yes. For example I have a Seiko dress watch (dress style case) with a 6309 movement in it which I would not take diving, similarly, I have a Seiko divers watch with the same movement in it (6309) which is a diving watch. The only difference is the case (and crown sealing system), the diving watch case is made for diving due to it's more robust seal system on the case and its a more rugged design. Seiko 6309 divers watch: Seiko 6309 dress watch:
    • I mean let's say a was to make a dives watch is this mean as long the case is a dives case and a fits the movement it should be ok and is this means any movement longs it fit the dives case?
