Not just the bezel has been made in ceramic planet ocean 600 m omega co-axial master chronometer 39.5 mm replica watch, also the dial is made in a polished ceramic (which is discretely printed on the dial.This 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.
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. The 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.When we reviewed the Seamaster Planet Ocean GMT (back than named Seamaster Planet Ocean 600m GMT) we just loved it and considered it to be a perfect travel / dive watch.
Now the other big novelty about the new Omega Seamster Planet Ocean Replica is not cosmetic, but inside. 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. That’s where Omega’s Master Co-Axial movement ticks at a rather unusual pace. If you’re wondering what a “co-axial escapement” actually is, there’s a short video (here), which we showed you several years ago, that very clearly explains how the co-axial escapement actually works.
In our review we already explained in depth how easy the Seamaster Planet Ocean can be set and adjusted, something that is extremely convenient when traveling. Pull the crown and in the first position you can adjust the hour hand with one-hour increments, without compromising the time-keeping; in other words the movement keeps running while adjusting the hour hand to another timezone while traveling.
This escapement is used in the Master Co-Axial movements that were first introduced early 2013 (see here) and slowly found their way into the collection in 2014 (see here). These movements are completely anti-magnetic and they are all tested and Chronometer certified in-house, according to the METAS procedures (as we explained here). Last year we visited the new testing facilities and we published a 2-part report; part 1 is here and part 2 is here.
This could well be your perfect traveller watch as is has the additional function of the second time zone; something that comes in handy while travelling.In 2013 Omega introduced the Seamaster Planet Ocean 600m GMT and that was the first Planet Ocean with a second time zone. That’s eight years after the introduction of the Seamaster Planet Ocean Replica collection.
The watch comes on a steel bracelet or a black leather strap with rubber lining. The leather strap with rubber lining has also been improved. Because of a special treatment to the leather it is less sensitive to water and you can easily take a plunge with the Omega replica watch on the leather strap on the wrist. The bracelet for instance has been changed on some accounts a the biggest improvement is that the first link, which is attached to the case, is now in a U-shape instead of a T-shape. While just this info might sound kind of generic there’s actually much more to it. That actually means that the bracelet is easier to fit on a smaller wrist, which we think is very good, whether you have small or big wrists.
