Dave Pak - New To Watch Repair


DavePak

Recommended Posts

Hi,
I was retired for two years from an R & D lab and took a part time job in a Jewelry store. The job was for a watch repairman (will train), but the training was very limited.
I find this field very interesting and may have pursued it in my youth. I'm currently working on a Hattori VD85 by replacing the movement but, I'm confused about setting the
"Day" hand. I broke the stem and have to retrieve it before continuing (don't tell the boss). I'm going to tackel the stem retrieval but, would like to know if there is a procedure to

setting and indexing the "Day" hand.

 

P.S. Mark does such an excellent job with his videos. He gives me the confidence to pursue this career.

Happy to find such a site.

 

TKS,

 

Dave.

Hi Vic,

Good stuff. I responded to clockboy (see post) and maybe it's me but, I have no way to determine where the "Day" hand post is located. I don't know where to place the hand.

 

Thanks again,

 

Dave.

Hello Dave,

The PDF shows the dismantling procedure numerically from 1 to 23 and the assembly is from 23 to 1.  It also shows a pic of the dial for your model.  Can you work out where it goes by following the procedure or does it not help.

The only other thing I can suggest is a few pictures of the part and movement so we have a better idea of the problem.  I am sure someone will be able to advise.

 

Cheers,

 

Vic

Dave,

Can I suggest that you start a separate thread in the help and advice and post the query with some photos there as this thread was started by Stryker11 and there are two separate queries going on at once. I will hook up to your query there.

Cheers,

Vic

"I have no way to determine where the "Day" hand post is located. I don't know where to place the hand."

 

Dave something occurred to me, I once worked on a Rotary watch that had a Miyota movement and two sub dials plus moonphase and some other pretty useless decorative stuff.  I had not realised that when I removed the tiny hands from the subdial I had effectively decapitated the pinions and the ends were left in the hands.

I had to get a replacement movement as a fix was not feasible. Is the hand post you refer to the pinion and if so is it possible it has been broken off meaning there is no where now to affix the hand.  The pinions I worked on were extremely thin and fragile and any sideways pressure was always going to snap them the hands need to be removed vertically.

 

Just a thought,

 

Vic

Sorry guys,

I didn't realize I had 2 posts going. Didn't mean to not respond to some of these posts.

Let me get some pics.

I'm trying to remove the broken stem first without too much disassembly.

 

Talk to you soon,

Dave

    • That's the right technique Mal 👍 If you are ok with a loupe ( which I'm not ) then pick up the dial in your left hand and make a tripod holder out of 3 fingers and then exactly how Mal and me described with your right hand, press and flick out the stem at the same time. You need three fingers to do this, i use my ring ring finger , sounds like mal uses his little finger, just whatever you feel comfortable with. The key point and dangerous side to this is the tweezers or driver slipping off the release screw. Stablise your left arm by resting your elbow on your bench, so that you can hold the movement horizontally flat, use a x5 loupe to view  and good light so you can see well and have a good tight fitting screwdriver to push the release down. Or as suggested a pusher mounted solid upside-down somewhere then all you need to do is push your movement up to it. I'll rig something up in a bit to show you what i mean.
    • Thanks Michael, shes a real soldier, it would take a tank to knock her off her feet.  Shes surprised even me and i knew she was a tough cookie.  Good for you Michael, you keep at it. I've been reading your posts re. your watchroom they're inspiring and it doesn't matter how long it takes you to get there its about the journey. Rome wasn't built in a day, our watchcaves are our solitudes, our own little empires where we can shut ourselves away from the crap that goes on around us in the world. I look forward to seeing you progress, I have my own ideas how i like to do things. But in answer to your questions on that thread, just let your workspace evolve around you and how you work. You wont figure it out straight away but you will know when to change it and when to leave it alone. But most of all just enjoy it.
    • That can be tricky. Sometimes I hold the movement from the edges in left hand and with right hand I push the release with tweezers and simultaneously pull the stem out with right hand pinky or something. 
    • I see what you mean. I must admit I’m not entirely comfortable with that but I can’t see a better method than what you suggest. I’d like to see something like this mirror with a short spike: https://www.cousinsuk.com/product/mirror-for-observing-movements Place it on, push the spike on the post with one hand and release the stem with the other hand. Minor problem, it doesn’t exist.
    • Hope you mum keeps on mending. I was adamant that I was going to get myself going after my stroke. I was only 52. I still have a lot of life left to live. Some people give up. Some people don't let it beat them. Your mum sounds like one of the winners. 👍
