Omega Seamaster Planet Ocean GMT comes in a different size (43.5 mm) than the two ‘normal’ Planet Ocean models (42 mm or 45.5 mm) and this new edition with Co-Axial movement sports the same 43.5 mm case. The case’s thickness has been reduced from 17.25 mm on the old Seamaster Planet Ocean 600m GMT, to 17.04 mm on the new model – reduced but still a hefty watch and not one that easily fits under the cuff of a nice shirt - Omega Seamaster Planet Ocean replica.
Omega Seamaster Planet Ocean GMT features a black and white bezel (day and night for the GMT hand) that is made in polished bi-ceramic. This is a world’s first, since “the other” 2-tone ceramic bezel (from Rolex) is actually made in one colour and treated afterwards to get the two colours! This black & white bezel features numerals and scaling in contrasting colours. Not just the bezel has been made in ceramic ZrO2, also the dial is made in a polished ceramic (which is discretely printed on the dial.)
Omega Seamster Planet Ocean GMT is not cosmetic, but inside. That’s where Omega’s Master Co-Axial movement ticks at a rather unusual pace. Let me explain… Most modern movement run at a frequency of 28,800 vibrations per hour, some have a higher speed of 36,000 and some at lower speed of 18,000 or sometimes 21,600 vibrations per hour. The Co-Axial Master Chronometer Calibre 8906 runs at a frequency of 25’200 vph (3.5Hz) and that’s according to Omega the best speed for the co-axial escapement that they use.
