Hi Everyone,
Recently I have become obsessed with ana digi watches from the 1980's! I really dig the style for some reason.

I was looking on ebay in the low price ranges and I found this little nugget for the princely sum of $5.70 - the shipping from Peru was an inflated $20 AUD - so I got away with it for under $30.

It came well packed in a little padded envelope. It was missing the back, had severe damage, but I didn't see any rust stains on the back.

It is a Seiko H127A-5000 - the year could be between 1979 and 1980 - there is a little bit of info around the internet.

The case back will be an insanely rare part to find so I may have to CNC mill something or potentially 3d print a plastic back.
That is if I can get it working.

The Crystal is trash. I've tried sanding it, will wait till I have some crystal polish - I haven't had much luck polishing mineral crystals.
A new crystal is around $35 - with OEM Seiko writing.

I removed the movement and soaked it in WD40 to loosen all the bolts. It was too seized to attempt opening.
The LCD panel/dial has a crack in it. The sub assembly appears clean, the zebra strips on the LCD were a bit gummed up but cleaned up.

Happily the analogue movement was turning over freely, it wasn't ticking - but likely due to so much grit and much on the contacts.

The only corrosion was on the rotor, and some of the non important chrome plated parts.
I've soaked them in shellite. Cleaned with blutac and then inspected under microscope.
Everything appears fine.

It is a very high end movement with 8 jewels and all metal parts - it would have been top of the line back in the day. Very tiny parts.

The main circuit board is out - my it looks complicated.

Simple plain jane movement - nothing fancy: It's all inside:

The bridge is off and the rotor is next to the movement:

Cleaning the case:

Tonight I have finished cleaning everything - I have put it into my movement parts tray - awaiting some time after work tommorow.

If anyone knows how the LCD works please let me know - is the display in the top dial section? Or the next layer down? There is a white mirror presumably to reflect the light off the screen as this is the black model version (there were two models).


Parts look pricey and rare - I've found a dial panel NOS - also crystals online. May have to look for circuit board if its fried -

 

Can't find any bracelets - may have to go non OEM generic  steel band.

 

Goal is to get it running - if its not running - atleast to be a show piece in my cabinet.

More soon :)

Good luck! I have a number of fried ani-digi Seiko watches, mainly H608 from memory? No luck in getting any of them running yet so I’ll be following your progress with interest.

What's up WRT peeps!
I finally have some updaaaaaaaaaaatees :)

The story with the watch above was that it needed a case back and a replacement LCD panel.

I have been watching eBay for a while, there have been 3 watches sold since: $850, $450, $280 for working examples. The former of which was a mint example.

The prices have doubled from 3 years ago, where a mint NOS example cost $300-400.

Anyway - I bought a nice B grade donor watch which was 100% complete, however it had a cracked/bleeding LCD panel.
It only cost me $25 from germany (eBay) which is surprising because nobody else bid on it.
Luckily I knew that Northern Watch Clock Co had a 4510-841 replacement LCD panel for sale for 15 gbp.
It was the correct panel for the donor watch as the original had the dark dial which was possible rarer?


I ordered the part, after paying an absolutely eye watering 25GBP for postage, (it arrived with an 8gbp postage stamp - 14 days after ordering.waaat...). It wasn't packed that well considering how incredibly rare this part is. Cousins as an example posted me a 30x30x30cm carboard box just for a mainspring - atleast it was protected haha!!!

Right, my turn then Alexei, you have inspired me! Mine is in remarkably good condition cosmetically, it all looks clean inside too so hopefully it will work. It is the black dial one that you think is more rare? So I just need an LCD panel now. It seems you may have bought the last one available, so the hunt is on. If you found anywhere else that had one I'd be grateful if you could lee me know? I need the dark one which is 4510.840 as opposed to your 4510.841 (I think, anyway, not 100% sure difference between 840 black and 841 white).

Do you know, I had taken on so many other projects that I had prettty much forgotten about this one. I've had an ebay search for the panel going for months with no joy yet. But I did see a video a few weeks ago where someone basically squeezed out the lcd bleed on an old lcd watch. I don't have much hope that it's going to work on this one but I will give it a go, nothing to lose and all that.

If anyone does come across a 4510840 lcd panel though, well you know who to tell...!

Hiya Pip. I will keep an eye out. I'm looking for another one too as I have 1 more donor one to fix.
Your LCD looks to have a small crack in it.

I am afraid the parts will not come up easily as they are always the first part to crack. I think that people are a bit rough putting the battery in, or there is no shock protection on the case back when it is pressed in, resulting in a crack to the glass.

They are great watches, I've seen a few changes hands recently for only $100.

      Like losing Ranfft. That was a wake up call. We took his website for granted. Miss him terribly.

      Its 4 o'clock in the morning here in the Uk, i cant sleep, i dont sleep, not much ever really. My brain never shuts off to rest, I'm just a constant thinker, i have to be very tired to be able to sleep,  i guess eventually it will be my undoing and my health will suffer because of it I'm sure. But while I'm here i want to get as much out of life as i can, and give as much as i can, to help,maybe to make a difference to someone's life if that is within my capability,recent events have made that need even more clear to me. I'm not sure where I'm going with this or why i bring it up , or if its relevant to want i want to talk about its just in my head right now. What i do want to talk about is something thats been on my mind for ages. I like to be prepared,  I'm not fond of surprises because surprises take control away and i am a bit of a control freak at times. This forum, Our Forum if i can call it that, is here because of two reasons. The guy that created it and keeps it funded and the people that joined it.  Without either, it would not exist, and lets face it one day it won't ( I'm a realist and i talk about things others dont or who are afraid to in other words folk that dont particularly prepare for the inevitable). How many of us visit here regularly ?  How many among us almost depend on the forum as a way of socialising because they are stuck at home and how many of us has it become part of a daily routine to check in and see if they can offer advice or get help with something they are working on or just to have a chat and engage in some banter. The members here are in the thousands and thousands have disappeared over the years many had just a fleeting visit. But there are a good few of us that know each other quite well and visit regularly. I dont know about you but i wouldnt want to lose that communication with you all, in all honesty it has become an important part of that side of my life and helps to feed my passion for all things watches. Some of you may think differently and thats ok, some of may stop and think # what would i do " Without Our Forum " #

      Naptha appears to be a general name and its content can be varied depending upon what it's specific use is. Lighter fluid as an example can be light or heavier also with other ingredients to help it burn. Try sesrching for benzine ( as opposed to benzene which is linked to causing health issues ) . There are other fluids such as ethanol that you could try and also methylated sprirts, mostly ethanol with a small percentage of methanol added. Experiment with any new chemical to see how quickly schellac dissolves in its presence. I have tried a few things but hexane is not one of them, i understand it does evaporate very quickly.  Be sure sure to check out any safety data on chemicals you try. Toxicity of fumes and flash point information, ultrasonic machines can heat up fluids even without a heater function. And of course always ask here for personal opinions when trying a new substance.

      What tools does ebay have to offer this week.

      By GuyMontag · Posted

      I have that set and really like it. I prefer that crystal holder over the one that came with my Bergeon claw tool and any time I use the claw I use this one instead of the Bergeon one, just an additional bonus with this tool.

      Is the Roamer not a split stem? I'm confused on your how your case is put together. If it is a front loader where is it you are putting the case screws? I love me some Roamer, do you have any photos?
