Time-only automatic movement without date complication, introduced in 1990 and used until around 2001. Featured in non-date models like the Submariner 14060, Explorer 14270, and Air-King. The bidirectional automatic winding system uses double-click wheels similar to ETA/Eterna design. Uses flat hairspring without regulator and adjustable-mass balance. The Explorer version was COSC certified but the non-date Submariner was not.
