For 2012 Omega released a new 18k red gold version of the Seamaster Planet Ocean three-hand and chronograph models with a new type of "Ceragold" bezel. Ceragold is more or less the gold version of Liquidmetal (that I discussed in more detail here). It is a special process that Omega uses to inset gold in the engraved ceramic bezel. In a sense, this is Omega's answer to Rolex's Cerachrom.
So why isn't it just "gold Liquidmetal"? Because it isn't. The Liquidmetal process is very similar to Ceragold, but uses a different type of metal. Ceragold actually uses gold. In a nutshell, the ceramic bezel is formed and then the numeral and index holes are engraved in the ceramic bezel disc. After a conductive layer is formed in the engraved area, layers of 18k red gold are applied using an "electroforming" process. Next, the excess gold is polished off and the Ceragold bezel is finished. Omega details the Ceragold process rather well here.
So as you can see, Ceragold is similar to Liquidmetal, but not quite the same. Plus, it is a cool term. Note that as of now it only applies to the forming of the bezel. Each of the watches I have photographed are 18k red gold on black, but there are also white with gold models available. The black and gold models are extremely sexy though.
These watches are the 45.5mm wide versions of the Seamaster PO. There is the chronograph and three-hand version available with the Ceragold bezel - both look pretty fantastic. Omega will also offer the smaller three-hand Seamaster PO in the 42mm wide case with the Ceragold bezel. The watches contain in-house made Omega automatic movements. For more information about the Omega Seamaster Planet Ocean watches see my review here.
Being gold models these watches have the higher-end 8501 or 9301 calibre movements. These versions of the 8500 and 9300 movement range have 18k red gold bridges and rotors. At this time I don't think there is a matching 18k red gold bracelet, but the watches do come on black alligator straps. Omega makes a damn solid diver and nothing is lost here with the 18k red gold versions of the Seamaster Planet Ocean Ceragold models. Prices are $22,500 for the 42mm PO, $25,000 for the 45.5mm PO, and $33,000 for the 45.5mm PO Chronograph Ceragold models.
