This Polaris is simply extraordinary.
It was and still is a modern watch, but born 44 years before !
On the wrist, it's perfect too.
Yep, let's wait, see and pray for a reedition of this model.
I'll try to post ASAP some pics of the Polaris and the A I together, and you'll notice, as said by Christian, that
effectively, the case and the caseback of these 2 watches are very very close.
