I'm sure you will get help on here soon. 

Kkramme we like new members to make an introduction before posting. A little about your self such as where you life and what got you interested in Horology

Thanks. I did make a self introduction— perhaps in the wrong place? 🤔😢In any I am an Australian 🇦🇺 American living in the beautiful Gold Coast, Queensland Australia. I love Grand Seiko and Seiko watches, and recently came back from the Grand Seiko Shizukuishi Studio in northern Japan where I was blown away by the design artistry and technical excellence. More later on that (including photos, if interested!)

Here are some photos of the undamaged and damaged coil.  My bad!  I find it interesting because it is an "old" Seiko Credor -- which later evolved into $20K watches!

Sometimes surface damage like this can be repaired with solder. Run pre-tinned soldering iron tip with a tiny blob of solder over the damaged area and pray that the Gods of watchmaking are on your side. 🤞

the problem with vintage watches and yes quartz watches can be vintage is availability of parts will be a problem. I have a link below where we can cross reference the coil and  I was hoping for more.

Another problem for vintage parts are everyone on the group gets used to ordering from online. Conceivably the physical material houses that still exist out there might have the part and you'd have to reach out to them and see if anyone has one. this is because they don't list every single part that they have online with the exception of cousins where everything they do is online work just doesn't exist but the other material houses can have stuff not listed.

Otherwise just set up a search on eBay and sooner or later it will possibly show up if you're lucky.

You don't have to use his special tester. Any good multimeter would work.

Thanks.🙏 Very helpful.

Hi. Breaks like this can br fixed with conductive paint like the paint used to repair a car  rear screen heater. I have used it successfully, you don’t need much and unlike solder there is no heat

What a cool and talented and helpful group/community!   Well done -- and much appreciated!

Yep, i pulled that up as well when i was looking,  there is definitely parts out there if you are prepared to go out and find them.

I watched that video years ago, I'm not so sure about probing the coil like that. If you are going to touch the coil use the side of the probe or at least shape a nice round end to it.

Hi. It’s always better to replace the coil but in the event of being unable to find one it’s nice to know that repairs can be effected. I prefer the conductive paint option because of the lack of heat and the chance of causing further damage.

Would the paint increase the resistance of the coil ?

Effectively joining the wires that are painted. I imagine its important to only paint the smallest of areas to make the repair.

In think you are effectively shortening the coil by shorting out damaged tracks. In my case as long as the continuity was good and the resistance not too greatly affected it should be ok .  One was on an era  movement,

Thanks ww, its maybe not as much of a bodge trick that i thought it was.

Hi New. More of a get you out of a hole than a bodge. There is no substitute for a new coil.

Unfortunately after much investigation, apparently the coil has been discontinued! Shall I get my service guy to try the solder or the conductive paint? 🎨 Final recommendation please🙏

[Myota2034] Custom simple quartz watch — PricewaterhouseCoopers

On a very very different note, here is a watch from approximately 2000 when I was a Partner with PwC, Management Consulting.

It was a simple “marketing watch” with a clever “vase of knowledge” that is subtly revealed on the dial as the second hand progresses.

Clever for a simple watch!⌚

    • Guys, thanks for your help! According to the advice of a colleague @nevenbekriev, I managed to straighten the spring. Surprisingly, it turned out completely flat. Like new. And the watch after that, for the first time since it was with me, started running late. 🙂 That's great news!!! The rotation of the weights is about 190/200 degrees. In the past 12 hours, it was 4 minutes late. I still have enough room to speed it up. Looks like everything will be OK.  Thank you very much for your help!
    • Thank you for this post. Adding on to it, I've done a little digging trying to get the most bang for my buck. So I really wanted a set that had a base. You can buy the screwdrivers for around $33 usd 10 Piece Screwdriver Set. The base is around $32 usd Rotating Screwdriver Base (Grey) plus $20 in shipping, with tax you are looking at about $90 which is an excellent deal for what you get but I still didn't want to spend that much. I saw that they had the 9 piece set w/ base for $59 usd 9 Piece Screwdriver Set W/Base and I had a 'welcome discount' and got a matching 3mm screwdriver for 99 cents. 3mm Screwdriver. (without the discount the screwdriver is $6) With free shipping my total was $66.55 usd. So, I saved about $24 to go without a slot for a 3mm screwdriver. I'll take that! I hope this helps anyone looking to save a buck or two. Also, this corrects the issue of the orange 1.8mm screwdriver. 😉
    • No hex wrench needed there. Screw driver in case of AS1475 or just push the poinst down in case of Poljot2612.
    • Well, what is written here can't be explained with the wear of the winding/sliding pinion. Probably it is some kind of delusion from You side. But it prevented the people from pointing the reason of what is happening. Otherwice, this kind of wear is one of the common problems of winding works in watch movements. It meets often in old or cheap movements, or particulary in negative stem system pocket movements where not proper adjustment of the sleeve that guides the stem is done.
