Omega Seamaster Planet Ocean 600M Co-Axial Master Chronometer 39.5mm Watches

The Omega Semaster Planet Ocean Collection has now been adorned with the "Master Chronometer" certification. Not only is the movement certified by the Controle Officiel Suisse des Chronometres (COSC), but each and every timepiece is tested by the Swiss Federal Institute of Metrology (METAS). The smallest of the new models with 39.5mm, this collection provides top quality timekeeping without being overbearing - for those with humbler tastes and/or smaller wrists.
