TPD reference
Omega TPD Information
Winding direction and turns per day for Omega movements. Set your winder to the figure beside the reference you own; where a row names a calibre rather than a reference, it applies to every model carrying that calibre.
Most modern Omega Co-Axial Master Chronometer calibres — the 8800, 8900 and their relations — want 650 TPD bidirectional, which is the lowest setting on a good winder. The Speedmaster Moonwatch is hand-wound and needs no winder at all.
