The Planet Ocean 600M Co-Axial 43.5 Master Chronometer reference 215.33.44.21.01.001 was introduced at BaselWorld 2016, as part of the third generation of Planet Ocean models. It is powered by the Master Co-Axial caliber 8900, which is housed in a case of 43.5mm – a size previously only available in the GMT model. The dial is made of black ceramic, as is its bezel.
