Omega designed the Omega Seamaster Planet Ocean GMT Deep Black Watches Replica to have a black ceramic case, bezel, as well as dial. The case is one piece of ceramic, and the finishing depends on the model. This isn’t easy to see in the stock pictures, but the 18k Sedna gold and black ceramic models have polished cases, while models like the blue or red accented Deep Black watches have matte-finished cases and dials.

This is a valuable extension to the already updated for 2016 omega seamaster replica family with a few interesting twists. Of course, the most important is that the “Deep Black” is the Planet Ocean’s take on the Speedmaster Dark Side Of The Moon (review here) that very successfully translated the appeal of the Speedmaster’s polished steel case into a polished black ceramic piece.

I have a feeling that omega seamaster planet ocean replica models will continue in the future with additional models, but at launch the first models offer a unique combination of elements making for a compelling model aside from the new black ceramic case. It is, however, also worth noting that this is the first 600-meter water-resistant dive watch in ceramic that I know of. I don’t know enough about how ceramic handles high pressure, but it is possible that some clever engineering was required to make the Omega Seamaster Planet Ocean Deep Black model possible.

Omega further employs their Liquidmetal or Ceragold (same as Liquidmetal but uses gold) technology on the bezels and crowns to apply the markers and Omega logo. The benefit of this technology is best explained in terms of wear resistance. Rather than print on top of the ceramic material, omega replica watches used melted metal to fill in channels to create the markers – which will not scratch away. This is a good thing for people who like their watches to look better, longer. When it comes to colors such as red or blue (on those models), Omega uses injected vulcanized rubber as they did on other 2016 Omega Seamaster Planet Ocean models that were debuted at Baselworld.
