First Project Ideas & Help Needed


Recommended Posts

Background: I know absolutely nothing about how to fix watches. I purchased this Hanowa Swiss Military movement ISA 2330 for $32 on ebay in 2016. I forgot I had it until my other daily watch broke (also Hanowa). After taking it to a watch repair shop to get the battery replaced, we discovered that the second-hand kept sticking. The watch store clerk thought it was the battery, but even after replacing a new one the second hand continued to stick. He recommended doing a "total overhaul". Because I didn't pay very much, I figured it would be a good first project to fix on my own. At first I thought about taking it apart to fix it but trashed that idea when discovering the movement itself is only $16! I guess I expected the movement to be more pricey since a new watch replacement is close to $200. Apologies in advance for those who will shriek at my questions. 

So here is what I would like to accomplish:

- A solution that is easy, long-lasting and easy to maintain. Basically, what would I have to do to keep this watch running for the next 30 years. 

- Preferably budgeted under $75

Thoughts and questions:

1) Are there "better" movements that I should consider using that will fit this watch?

2) Since I want long-term function, would it be better to make this an automatic movement?

3) How long would a replacement ISA 2330 movement last and is it my best option to keep the watch original?

New movement $15.95....quartz is not the easiest to work on esp if you don’t know what you are doing tools used on quartz movements are also very specific. So i suggest just a quick and easy movement swap. It’s the most basic thing you can learn if you are new to the hobby. Learn to remove stem, dial, and hands. Then re-assemble. You will need watchmaker non-magnetic screwdrivers/tweezers, hand puller, and hand setter.

Hi SASwatch is correct, as at the moment your knowledge is zero, now is the lime to learn the basics that being removing case backs, removing stems, removing hands and basicaly swapping the movement which if done correctly will last quite a long time and you would have gained the first foot on the ladder which is watch repair and servicing.

First pick up some reasonably priced screwdrivers case knife eyeglass (loupe) 5X and a medium priced pair of No5 tweezers this should enable you to change the movement. If you intend to continue with the hobby you can always add more and trade up in quality.

The tech data sheet contains very little information of use to you at the moment.

ahhh weasol I almost forgot case back opener duhhh, and def eye loop. Only thing i would say different is tweezer number 3 or even number 2 something with wider and tapered shanks. #5 is way too thin and mostly reserved for very fine detailed work. Someone experienced prob could use it for mostly anything but to a beginner it could mean many screws and parts flying across the room. OP just make sure they are non magnetic, because anything that becomes magnetized could potentially do harm to a quartz movement even more so than a mechanical.

Thank you both for you advice and information! I purchased the following items from esslinger today and they should be arriving next week. I am looking forward to working on this small project and having the watch back to working order. I already had the tool to take the back off and a pair of cheap tweezers that came with the amazon set purchased earlier. The one thing I didn't include was cleaning supplies because I didn't know if they were necessary for just replacing the movement. I chose to get the finger cots as a second option.

Looks good to me does the tweezer set come with a brass pair or are they anti magnetic?

Hi  Good,  looks comprehensive enough to start with. As saswatch says No 5 probably too fine, go with his suggestion.  If you are going to be changing batteries A plastic pair or ones with plastic tips but other than that you have done ok. One other thing  if you are working on mechanical watches consider a de-magnetiser as a potential future purchase.

Hi  Nows the time to start pick what looks like the simplest one and go for it. Remember you are not alone there are many members on here to help and are willing to help. When posting questions about a problem if you can always where possible quote the make and calibre of the watch and a pictures of the front and back, they go along way to help.  By The way  take pictures as you go for reference in case it all goes pear shaped.

Just a word of caution before you get stuck in ... the finish on dials tends to be very fragile so don't use your new hand remover without some protection in place. You can get pro dial protectors but as a beginner some suitable soft plastic would be fine. 

Watchmaker - I wish I would have read your comment earlier lol. I did in fact ruin the second hand with the tools. After ordering a new set of hands, the watch has been working perfectly! I love it and wear it daily.

    • Welcome to the forum, enjoy. It’s highly unlikely you will be able to purchase a new bezel look on eBay for a pulsar watch for repair to find a bezel.
    • just one little minor reminder here this isn't your normal balance wheel.  pages 17 and 18 are what you really want to be looking at. normally studs don't turn but this watch has the etachron system designed for lots of adjustment. Personally I would try to rotate the stud back to where it's supposed to be. If you're lucky you didn't actually bend it at the stud it just looks really bad as the stud has been rotated grossly out of position.. I think things will look a lot better if you put the hairspring back where it's supposed to be by rotating the stud. it's hard to tell if you actually did bend it at the stud or not we won't know until you rotate the stud back more or less where it's supposed to be. Then you want to pay attention to the manual of how to put the hairspring back in the regulator pins because yes they rotate also and they rotated specific directions otherwise bad things will happen to your hairspring. so initially you can open up the regulator as wide as it can go and don't worry about closing it until thing everything is right then you can close them a little bit
    • I need to see photos of the whole movement before I comment. 
    • Hi @Jon, so, from one extreme to another the beat error is 0.1(min.pos) to 0.2(msx.pos), and as you mentioned the rate does up and down dramatically. Also checked the position of the collet, and the collet is not central to the jewel on the balance cock. Balance moves freely, per my understanding.   So, after 24h the ampl. fell down by approx 20 deg, which I would assume is expected. After adjusting the endshake I believe I gained around +10 deg. of balance movement. Which is great, and overall the balance is not at 220'ish deg.   What I did next, some might think is non-orthodox, but was wort a try. I too the mainspring out, checked again for endshake and if the pin moves freely, and cleaned everything. Usually when installing the mainspring I would use some barrel grease on the barrel walls, install the spring and put a 2-3 drops of D-5 oil on top of the wounded spring and in the places where the arbor sits. This time I took the spring and applied a ultra this coat of Molykote Dx paste on the whole spring, before installing it in to the barrel, and added some oil to the arbor as usual.  The result improved, at a full wound the balance produces about 230-237 deg. @JohnR725 I'm getting closer to 300 😃   What I am noticing, there is a fluctuation in amplitude. With time it would rise and drop about total 8-10 deg in an interval about 2 minutes. I assumed this ruled out the power transfer from the barrel itself. So I took the gear train out, cleaned and lubed. 
    • Thank you so much, Hector and CJ. I appreciate the tech sheet and the video. Gasp, I think I will make the attempt. What's the worst that can happen? I think there may be a new balance complete in my future, though.  I'll update the post and let you know the result. R, Frank
