New Movements For Practicing On, Very Cheap.


Geo

Recommended Posts

I checked them out, but the postage to Australia is prohibitive. $US9 for the card of 5 movements, but $almost $US35 postage (that's about $Aus42). I know the total is still a cheap lot, but it's a bit hard to swallow the postage as being 4 times the price of the goods!

Ahh bugger it! I just ordered 2 cards of them - 10 movements. It hurt to pay for that postage though - I buy a fair bit of stuff from the USA, much bigger and heavier than these things, and the postage is usually a fraction of this. I suspect it's a swings/roundabouts thing on the price - attract buyers with the low price, but scalp a bit extra on the postage.

 

Never mind - I'll now have 10 movements I can stuff up! ;)

Just so you guys know, these movements are FE or Cupillard caliber 233-60 with LeJour branding.  I looked them up and individually even for parts they are selling for around $25 so I might relist a few at some point. Seems like only one movement has sold in the past though.  I tried winding the first one out of the case and it doesn't seem to be running.  Will be a cool project getting at least one working.  Defiantly smaller than the Chinese movement too.

I tried winding all ten and there was only movement on one of them and the balance wheel just didn't seem to be going fast enough. If they are indeed NOS, is there anything that locks them from the factory?

There's a good chance that oil has dried out and turned into a sticky or hard varnish. Unless they have suffered some kind of mechanical damage, a thorough clean and lube should get them going.

naphtha work well enough?

Naptha (lighter fuel) will do the job OK. There are lots of articles on cleaning, of you do a search you will be able to check them out and see what will be best for you.

Talking of cleaning, I was considering one of these:

 

http://watchbitz.com.au/shop/index.php?_a=viewProd&productId=330

 

Plus a couple of baskets/trays.  That site is local to me, and provides an excellent service on tools etc. Given that (1) I'm a complete beginner, and (2) I'm not doing this commercially, I figured one of these budget cleaners may be all I need.

 

So the question - would something like this be useful for cleaning movements? Rather than one of those multiple-canister dipping machines like Mark uses in his videos?

Hi Pete,

 

I use something similar but I warn you it will take time vs. the commercial machines. If you calculate that every cycle is 10 min and you can only have one cycle at a time, one watch might take over 1/2 hour and sometimes more than 1 hour if you consider some parts are individually cleaned: hairspring ensemble attached to already clean main plate sans jewels, etc.

 

Then, hand dry all parts except screws. Hand clean jewels and/or assemblies. Dry them by hand too.

 

It is important to keep chemicals in beakers and then immerse the parts (inside their baskets) there, not directly into the ultrasonic machine which is filled with water (i.e. parts inside baskets, baskets inside beaker with chemicals and beakers inside ultrasonic filled with water). Therefore it calls for at least 3 beakers containing: cleaning fluid, rinsing fluid (dirtyish) and rinsing fluid (clean) = Three 10 min steps.

 

If in addition you clean other watch parts (wristbands/bracelets, backs, etc) it might take a good evening just doing that.

 

I personally have baskets that fit inside the beakers so I can lift the content of the beaker easily but it doesn't save time, just convenience. Therefore, I get everything I need to clean and clean it in one designated day. Then work on them another day.

 

It is noted that pre-cleaning preparation is important since all jewels need to be examined, pegged and examined one more time. It all adds to the cleaning process.

 

I hope this insight may help your choices,

 

Cheers,

 

Bob

 

PS. I would recommend a search on cleaning and cleaners in this forum too, very helpful to read other opinions and techniques on this interesting topic.

PS2. Lighter fluid is good but won't be safe in the ultrasonic. I rather use it for hand cleaning like in the old times.

Excellent advice, Bob, as always.  Thank you for that.

 

Just re the drying - would warm air drying be good, or is it a no-no for some reason?  Most surgical instruments are dried that way after cleaning, including ultrasonic cleaning. Some others with bits that are hard to reach are dried using acetone and warm air. I doubt that acetone would be good for watch parts though - am I right?

 

A simple warm air drier could be made using a box, a hood over the box, and a hairdrier set to its slowest speed blowing gently up into the hood - NOT into the box directly. With watch parts still in baskets, would that be any good rather than hand drying them?

That is correct Pete, heated blow dry is used by many people (example: hair dryer as you indicated). I personally have no experience with this method since I do mine by hand: holding the part with tweezers and blowing with hand pump. Acetone, alcohol and heat are a problem with pallet forks and balance wheel jewels since they are usually held in place with shellac.

 

I'm always afraid of blowing stuff into a watchmaker's black hole so I try not to even breath when manipulating the tiny parts. Somehow my system works considering my workroom is cluttered with many different and unrelated stuff, from reloading equipment to musical instruments to bookshelves to boxes full of tools and whatnots to my watchmaker hobby mini desk close to computer equipment in a corner....you get the picture. Part that falls is never found as a general rule although I've worked a mathematical equation, based in chaos theory, in which it is necessary to drop 4 parts to find the 5th dropped part, not necessarily the last one dropped. :)

I disassembled one of the ten movement tonight. I think i'm getting the hang of it! A few of the parts like the escape wheel and pallet seemed to be stuck in the jewel so it took a little extra pressure.  Probably gunked up with dried oil like you guys said.

@bobm12: Your man cave sounds very similar to mine, Bob :) I'm flat out finding floor space to step on!

 

One thing I did make, due to being a keen fly tyer for my trout fishing, is a three-sided "fence". It is made from some walnut, with each of the three sides (like a square with one side missing) is about 600mm long (about 2ft in the old lingo). The boards themselves are 80mm (about 3") which therefore is the height of the "fence". Some of the materials used in trying trout flies are virtually weightless (eg CDC feathers) and simply breathing out can make them take off over the horizon! But lots of things like tiny beads, hooks, bits of tinsel, etc etc all tend to roll or move - and all are stopped by the "fence". I keep everything inside the fence - i.e. where I'm working - clear, with tools, materials, etc all stashed outside the fence.

 

I'm now using that same fence for learning about watches. I've had one piece fly over the top when I wasn't smart enough to hold down a spring clip, but otherwise things have been stopped by the fence.

 

@Blake: would be very interested to hear if you succeeded in getting those el cheapo movements to work, since I've also ordered a couple of packs like you did.

Correction to the above post - I just measured the sides of my "fence" and they are 450mm long, not 600mm. So that's about 18" for you 'Murkins... :crazysmile:

 

Those dimensions give me enough room to get my forearms rested on the bench. When I'm tying flies, the vice is clamped to the front of the bench/desk, and I usually mount it towards the left side, with the business end pointing to the right and ending up about half way across the front. If you get my drift...

 

Unclamp the fly tying vice, pop it in the drawer, and hey presto - a watch fiddling bench :D

You guys think this is a good deal at $90? Would take about a 1.5-2 hour drive to go get it but the guy says it all works just has a half broken knob. Wife said we could take a day trip to go get so its good she's on board. I could restore it pretty easily like the other post I recently saw on here. It also included some of the metal mesh baskets.

Hi Blake,

 

I'm not familiar with those but I've seen the link to Micky's restoration which is super amazing.

 

To me, it seems a bit "used", that machine, but if it is still working - and you are handy and can restore it, - I see no reason why it should be a bad deal. It actually seems like a fun project if you actually enjoy doing that type of work. I believe they go for a lot more out there...but then, don't quote me since, as I said before, I'm not familiar with it...Won't hurt to at least have a look and it is still a good opportunity to enjoy a leisure trip with the wife.

 

In any case, maybe another member has a better opinion.

 

Cheers,

 

Bob

    • I understand the demand bit, the generation below me 30ish are too technology engrossed to own a mechanical watch and they just dont like old stuff. I also consider myself at the getting on age of 57 to be a rare find of someone that likes old stuff, i did buy an almost 100 year old book yesterday titled " The New Modern Home " printed 1929.  Cost me a quid. What i was trying to work out is if we have reached a volume peak of watches being discovered hidden in the back of drawers.  Those watches that were hung onto until they entered the hands of the non sentimental generation. 
    • Even for myself who only started getting into watch repair/servicing during COVID I have seen a huge jump in watch prices - we have a 404 channel on this forum. When I started you could relatively easily find a watch on eBay to restore and put onto the channel, however this is now almost impossible and the only feasible solution is to buy a job lot with an average price <4.04. Even watches sold for parts/spares are 3 or four times the price of only a few years ago. Why - Either Demand must have increased in order to push up the price, or supply is reduced. I think it is a little of both, I think that most watches in the UK/US may have been picked over, which agrees with most of what @Neverenoughwatches says so supply of all kinds of vintage watches, including tat is dwindling. As a double whammy I think that more people are wanting watches, either to work on, or as a way to differentiate themselves from the Apple Watch and FitBit crowd. The upshot is that half decent watches that require restoration are now $500 instead of $100 and cheaper watches (Seiko 5 etc) are now $50 instead of $10, and even Mumbai Specials and garbage are now pushing $50 each. When - how long will this last, I think that most of the people who are returning to mechanical watches are those that have previously experienced life without them and want to return to something with a bit of personality that doesn't buzz every 10 seconds on your wrist and tell you how many steps you have done today. i.e. the 30-40+ generation. My son who is 17 has several mechanical watches but only wears one on a special occasion and is obviously only aware of them at all in part due to my hobby. I asked him the other day how many of his friends wear a watch and he told me that some use a smart watch but most just use their phones. So as I see it, demand will start to fall once the sub-thirty crowd start becoming the majority and/or the older amongst us stop buying watches and switch our attention to mobility scooters and trying to remember our bank password. Price - I think this is here to stay, even if demand does start to drop as the older generation becomes to decrepit and stops buying and the younger generation isn't interested in buying, supply will become progressively less as time goes on as more vintage watches become lost or broken beyond repair. I think the prices will plateau at some point as an equilibrium is reached as reduced demand is balanced with reduced supply, i.e. less and less people buying less and less watches. Sorry for the long ramble!
    • Hi. Use a PVA based glue, gorilla glue it dries transparent then do as advised by Old Hippy, smoothe down using very fine  0000 wire wool and either French polish or beeswax for a finish.
    • Hello and welcome to the forum.    Enjoy
    • The problem with oil in particular 9010 is it likes to spread. This is why you're supposed to use epilam anywhere it's used to keep the oil in place. Then you want to splurge on money you could buy 941 it's actually an oil that existed before 9415. Then the problem with the grease yes it stays in place but if you have too much you lose amplitude. Then if you get really obsessed with this he would follow Omega's recommendation for escapement lubrication. One of the problems with internal documents of the watch companies is typically are never going to see Them.But a few of them out in the wild for instance at this link Below I searched for the keyword of working. In particular working instructions of the Omega watch company for which there is way more than This but this is all they have. So you want to download number 40 as were going to talk about that and also download Number 81. Plus anything else that looks interesting https://www.cousinsuk.com/document/search?SearchString=Working Then number 40 covers lubrication of the watch. Most interesting is lubrication of the lever escapement under three different conditions with Lubrifar Which you probably no longer have has been washed off without which is what you have and then a course with epilam. Notice how they go supers super minimalistic with the 9415 because if it's too heavy you lose amplitude. Then if you lose amplitude the group will be disappointed with you and the end of the world will come.
