Only thing is the Tissot/Pontiac/ChronoSwiss/Lemania/etc/etc variants would have a Lemania 872/1872 movement with e.g.‘Tissot’ on the bridge...and those are always a silvery (rhodium?) colored movement...not a copper movement. From my limited diving into these I have only seen Lemania-cloned-Omega’s as copper movements, and all regular Lemania (stamped ‘Tissot’ etc etc) always silver colored ... so I’m thinking that movement IS an actual Omega 860 movement ... the dial does not look redialed (the Omega printing actually looks kosher) ... would love to see that watch in hand.
