Thanks.
Two have gen movements (1570/1560).
All other have gen ETA 2824/2873/2846 movements.
All have gen tubus an gen crown..
The 1016 Explorers are built full of aftermarket parts.
All watches have Vietnams cases with correct serial.
At the moment i'm thinking about selling the 1016 Explorers to
fund a next gen 1560 movement.
best regards
Stephan
