Hi again! Now that I've removed the stem I see the dial has a sort of a thin transparency on it that is bubbly and I wish I could clean up its appearance. Would you possibly have any suggestions about this, or where I could view some instruction on it? Thanks.
Hmm, sounds like a layer of lacquer and my instinct is to not touch it. Dials are notoriously hard to repair or restore. The only thing I usually do is use Rodico to take off some light dirt and dust. Anything stronger risks damaging the dial permanently. The only practical options you have are to leave it as-is and call it patina, or find a replacement watch with a better dial. Sorry! If it helps, @MyRetroWatches has a good video where he cleans up a Seiko dial: th-cam.com/video/ixJYb2Z2YTQ/w-d-xo.html
Hi there. Yes, I could have a go, although it might be easier if you just let me know the model number written on the back of the watch. It should be eight digits with a hyphen in the middle, a bit like this: V401-5250
@@curiousassortment Thanks for that. The model number is 43-3349, and the first part of that is the movement number (43), which started production in 1975. I don't have that movement but I found a photo, and I'm pretty sure the stem release lever is the place where I highlighted here: imgur.com/pcJQlVx If you press that with a sharp object, you should be able to pull the stem out. If not, let me know! By the way, the first number you mentioned (6D2613) is your watch's serial number. The first two digits are the year and date, so it shows that it was made in December (D) of 1976 (6).
Question what’s the difference between seiko 7N43A and 7N43C. Is it the same I brought a watch that says 7N43A but it’s a dummy movement and want to know it 7N43C movement would work/ fix with no problem
Hi Charles. There is a very small difference between the two - according to the technical guides, the 7N43C is about 0.1mm thinner and has one jewel, whereas the 7N43A has no jewels. The actual width/diameter is identical so you should have no problems replacing the 7N43A dummy movement with a 7N43C movement. I've just updated my website ( mizeni.com/movements/seiko-7N43 ) with this info and links to the technical guide PDFs. Thanks for the question.
@@mizeni thankyou. I don't suppose you know what size dial fits it also? I'm figuring a 28 mm there abouts? Only I'm not seeing dials specific for that movement , so wondering what the best option is to have one for it....
Hi. Yes, it does. The second hand stops when the crown is pulled out two clicks. I found this video which shows it at around 01:55 -> th-cam.com/video/0rrLJc6pHmg/w-d-xo.html
I have this movement in a Sandoz which as given me good service for a few years. I know nothing about watches but like tinkering. Recently the watch stopped. I changed the battery and it worked for a while then stopped again. The next morning it had restarted. I adjusted the time and it refused to start. Its done this a couple of times. Any suggestions as to the problem?
Hi Ronald. Unfortunately I'm not sure what the problem is. The most likely things I can think of are battery (even though it's new, sometimes they're low on power from being old or poor quality), some kind of dirt inside the movement, or perhaps the hands are slightly bent and getting stuck when they pass a certain point. If the watch stops at the same time each day then this is a possibility, otherwise I think dirt inside might be the culprit.
Thank you for the prompt reply. I think I've cracked it. Here in Thailand maybe the batteries are not always genuine products and vary in size. I've stuck a small piece of duct tape on the back of the battery so that when the back is screwed down it holds it in place. It's working perfectly. Real Heath Robinson and I expect you are having a fit. But it's working. So far.😉@@mizeni
So happy I found this! I was stumped!!!
I followed your directions, and I was able to get the crown out after the 3rd try on my 7N42. Thank you.
Nice, and thanks for letting me know. If you got it out and nothing's broken, that's always a win in my book!
Well, that couldn't have been any quicker or easier. Thank you very much.
Your video and explanation were helpful in making the repair. Thanks
You're welcome! Glad it was helpful.
Thanks, I finally got a bit of crud off the watch face of a Lorus I've owned for 20 plus years! 😊
Great, glad to hear that! Ready for another 20 years…
Thank you! That thing is really difficult to see, even with magnification.
Sir,i still new to this,i had one question,did you know what battery size for seiko V743-8B50.?
I have severed coil in my 7N43 movement, do you think I can replace it with VX43 coil? Will it fit?

I agree - thanks.@@mizeni
I have an old seiko quartz. Can't find the release point for the stem. If I sent you a photo would you be able to spot it? Thanks.
Hi there. Yes, I could have a go, although it might be easier if you just let me know the model number written on the back of the watch. It should be eight digits with a hyphen in the middle, a bit like this: V401-5250
OK, on the back are two numbers; 6D2613, then under that is 43-3349. Thanks!@@mizeni

Hi, would anybody know where I can get a winder for my Seiko 7N42-0DE0? Thanks
What's the size of the case on this watch ?
Hi. It's quite small - 36mm diameter (37.7mm with crown).
@@mizeni thankyou. I don't suppose you know what size dial fits it also? I'm figuring a 28 mm there abouts? Only I'm not seeing dials specific for that movement , so wondering what the best option is to have one for it....

You're welcome! I appreciate your kind comment.
Does the 7N42 movement have a hacking function?
Hi. Yes, it does. The second hand stops when the crown is pulled out two clicks. I found this video which shows it at around 01:55 -> th-cam.com/video/0rrLJc6pHmg/w-d-xo.html
