This timepiece features another first for Planet Ocean: the world's premiere polished bi-ceramic black and white bezel ring. On the stainless steel case, the bi-directional rotating bezel separates night from day, with numerals and scaling in contrasting colours. If the colour of night wins out on the black ceramic dial, the numbers and scales shine through. The black leather strap with rubber lining is held fast with a foldover clasp in stainless steel. Both night and day, the watch keeps perfect timing thanks to its revolutionary movement: the Master Chronometer 8906.
