The watches in OMEGA’s Seamaster Planet Ocean collection have been held in equally high regard for their professional divers’ features, their style and their innovative Co-Axial technology since they were introduced in 2005. OMEGA has upgraded the entire family and each of the new Planet Oceans is equipped with one of the brand’s revolutionary family of in-house Co-Axial calibres – the 8500/8501, the 8520/8521 or the new 9300 chronograph. The movements also have the Si 14 silicon balance spring and the combination is so stable and reliable that OMEGA offers all of the new Planet Ocean watches with a full four-year warranty.
