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.
