Hi, I bought these two vintage Heuer chrome helmet clocks today. How rare are these? I've never seen them before until today while I was researching them, I usually see the none chrome ones.
The one on the left is in working order is the yellow second hand original?
The one on the right is missing the seconds hand and doesn't seem to work.
I'm looking to probably list both for sale the none working one I might look into replacing the movement if it doesn't sell and keep
How do I removed the helmet form the base the right one was easy to remove, on left one I didn't want to be rough and end up breaking anything.
