I've found a watch on eBay that looks fake (especially the mouvement doesn't seem right) but still being a noobie I'd like confirmation before reporting.
I‘ve found a few similar pieces online (same design but not two-tone) and they all had the Cal. 861 inside which is a manual-wound chronograph movement, so no rotor. Also none of them had a see-through casebacks. I would be very cautious here.
