My apologies to
@Masterofkarate and
@bimbim1207 for not responding to your queries on this one. I found myself conflicted and put my own interests first; I do hope you understand.
It is a bumper polerouter with case reference 20217-9. It's not a reference you see very often. The steel marker ring with gold hour markers is correct and is unique amongst Polerouters to this reference I think.
The serial of this watch is extremely close to that of the watch in the link above, which is the only other example I've seen of this reference.
The pictures were terrible though. Fingers crossed
@Larry S was wrong about the dial.
