Bought this 1960's Nivada watch on eBay. Works well on the Timegraph with nice clean lines so was very happy with my purchase, but then noticed the hour hand is out of sync with the minute hand.
Missed this totally on the photo from the listing shown here.
Problem is, how do I open the caseback? The watch only seems to have a small very flush fitting round porthole on the caseback.
Used rubber ball but no luck. No lip to try a caseback opener on.
Any ideas anyoneNivada?
