Movement seems to be a 1st generation one (Serial ~31.700.000), but the electronic was swaped out with a newer one. Depends on the price. I would not pay more than gold value + 400€ for a non original condition in working order. You should always ask if the date disk is ok (all 31 days). They often suffer from broken teeth.
Nice set.
Just asked her. Apparently it’s a big fat no.
Even though it just got her in more trouble. Or rather my watch budget just went up.
Thanks!
