I bought this watch on Ebay.  It looked interesting and was not a lot of money, so hey...a little project to hone my skills.

When it arrived, I wound it up and did some 'tic'ing and off and on some 'toc'ing.  But the balance was clearly sluggish...struggling for the next tic or toc.

So today, in a fit of boredom, I decided to clean it.

My first image is the watch as I saw it on Ebay.

I do not have the "proper" cleaning gear but I worked with what I had.  I took the watch down, put the components in lighter fluid followed by IPA for drying.  Interesting design.  The top plate has a pivot hole for a gear that does not exist.  A little confusing.  But...don't sweat the unknowns.

I did not have to (and wish I had not), but I removed the click spring.  This was really for fear that it would take flight during the cleaning process.  Well...lol...it did take flight...more on that later.

Here is an image of the the train wheels with the main plate removed.  The balance and pallet fork are already removed here.

Forgive the 60Hz in these photos...the lamp is florescent.

I also show the dial side with and without the date ring.  These pictures were primarily for helping me reassemble

I removed the mainspring from the barrel.  Inspected and put it back in.  Gave a little thanks to my Dad who assembled this watch bench and tools...the mainspring winder is cool!  Fun stuff.  Anyway, wound it and put it back in the barrel...no problem.  Oh wait!!! Ieeeeee!!!  I put it in backwards.  Oh well...more practice with the winder.

During the reassembly process--remember that click spring--I managed to send the click spring flying aaaawwwaaaayyyyy!

I have a sweeper magnet leaning against the wall next to the bench.  I took several sweeps and no spring.  Lots of other things (another story).

What to do?

Well, a month ago, I saw a bag-o=springs on Ebay...one gram worth.  I bought them.  Moreover, I had a small collection of springs that my Dad kept for such emergencies.

I found a spring that was really close, did some bending and cutting and voila!

I assembled the train wheels, oiled them, and applied power and they spun away.  Yay!

Assembled the mainspring, ratchet wheel and click (with my handcrafted click spring).

Then the pallet fork and balance wheel.

OK, I confess, I could not figure out what was going on with the balance pivot holes.  Some kind of metal on one side and jewel on the other...not like anything I have seen, so I did not try to break it down to clean and oil. 

After the movement was assembled, I took another sweep with the magnet and found the original click spring!!

Here is the movement after assembly.

I tell you, I felt like I was fluent in Swiss...or German with a Swiss accent!!

Then...all of a sudden...shite hits the fan.

While putting the hands on and adjusting them to get a perfect calendar roll over, something hit the one o'clock lume and it popped off.

No biggie...I will glue it on.  I did this once before on another watch.  Well, no bueno.  The glue caused the lume to fracture and it was a mess.

Who needs one o'clock anyways!  Nothing happens then.  It is not a happy hour.

Here is the final result (sans case).

That's my story!

Nice to read an honest "warts and all" account once in a while. With some practice and time to experiment with different colour lumes you could probably rescue it still.

Nice one! I agree with Klassiker, it’s great to hear a full story, especially one with some ups and downs. That looks like an interesting movement. Isn’t it the best feeling when you drop that balance in and...it works? ?

Did you ever figure out the balance jewels?

    • Yes, the steel (and iron) solders well, but good flux is needed. This will usually mean acid type of flux, and after soldering, the part must be well washed from the flux, which is usually done with base solutions that will neutralize the acid remains. Actually, I don't know the current state of the wheel, so I am not able to give correct advice. But yes, if needed, new pinion can be cut. No matter what material the cutting wheel is, it is needed to start with soft steel (O1 is OK). After cutting the leaves of the pinion, the work must be hardened and tempered and only then the rest of the work to be done.
    • I doubt that I know enough at this stage of my journey to impart anything useful. I have the Laurel here, with (finally) the back off.  I also looked on Yahoo Auctions, there is a seller at the moment with what they've listed as a Seiko Marvel balance staff, but I don't know if it's the right part for your watch. It seems you need the whole balance anyway, and I'm not seeing any of those for sale. There is a very trashed looking Marvel from another seller that might suit as a donor unit, but no photos even with the back off, and the crystal is missing. It doesn't look promising: the dial is severely corroded, so useful internal parts might not be salvageable.  https://auctions.yahoo.co.jp/jp/auction/w1112646076 https://auctions.yahoo.co.jp/jp/auction/o1185016360
    • You've been to Aladdin's cave I see! 👍
    • So not a hack then, but rather an upgrade to modern space-age shock protection! 🤣
    • I was able to find a little bit about this watch though a google image search; BENRUS H010 TECHNIQUARTZ 1972 1st US made Quartz made by Benrus. Using a custom E-block with the step Motor, a power switch and a Moto Chip driven by MotoQ at 32KHz on modified mechanical movement.   Well I swapped out the quartz. Still no joy. This looks to have a capacitor, it that the same as a coil. How on earth do I go about finding a replacement?
