Picked this up today, literally for nothing. Unfortunately after changing battery, still not working. Questions. Any tricks that might jump start a quartz watch. For example, I got another vintage quartz last week , wouldn't run after battery change. So before just throwing it out, I put it on a demagnetizer. The second hand spun like a top. I let it spin for a couple seconds. Watch then started up and has continued to work perfectly. I tried this on this new Crystron and the second hand spun, but watch still doesn't work. Any other tricks? Also do these Crystrons have any vintage/collectible appeal, such that it might be worth the cost of a service attempt. Thanks.

I have fixed hundreds of quartz watches and I'm sad to say that Japanese watches more often then not are broke and need a new coil or the circuit board needs changing. I generally don't bother with these watches anymore as it can get expensive to find working parts. One more problem is that they liked to use the crystal as part of holding the movement and dial in place and used a crystal with a thicker base and a new crystal like that is both hard to find and expensive. You can try the standard Sternkreuz Armored crystal and see how that goes or you can remove the armored ring from the old one and place it in a non armored crystal.

Very nice!

For a 1978 model I'm surprised they have so little protection for the coil. I have a 1980s model and they have gone overboard with both a protective metal cover and plastic film. :)

It is always a good idea to put a non working watch in a warm place with a fresh battery in it. I did this with a 80s Certina chronograph and sure enough it came back to life. Also look for a shuddering second hand when you put in a new battery as this means it's just in need of some blockage clearing.

Shum. This does have a plastic and metal cover. I didn't show it in the picture. Also the second hand was shuddering as you described. But I also got excited too soon . It is now back to shuddering and stopping again now. I'll just keep tweaking with it. Thanks for the help.

Ahhh. :)

What you need to do is get some Rodico and clean the movement (great for cleaning dials as well.) then get some quartz oil and oil the top jewels and pivot holes. This is normally all you need to do to get them back working again.

Rodico is like putty and you make a tiny ball and role it over everything you want to clean. Just be careful with the dial and only use minimal pressure as it can hurt the dial but this is mostly very glossy dials.

LOL, yes this is normal for me. I'm an old heavy metal guy and nights have always been my daytime. :)

I don't remember if one can see the jewel holes on the back side but you might need to clean and oil them as well but normally you don't need to and in the 80s you couldn't get at them anymore without taking the movement apart and doing that needs practice (a few broken movements).
