While Eterna is famous for its contribution to automatic winding, being the leader in a fully rotating automatic winding weight as opposed to the 'bumper' automatic, like any other swiss watches they started their wristwatch era with normal hand-winding watched. I found this watch on the net for a pittance,   Movement shot.. What I like about it.. -unusual movement (Eterna 1020), winding stuff is 'under' the barrel bridge' resulting in a nice clean appearance.
