By the looks and sounds its not actually a PVD case at all, but rather a solid ceramic one which is pretty damn cool!

just a higher res pic, if you click on it it'll get even bigger

 

ahhhh nice!!

 

Could very well be all ceramic, keeping in mind when it comes to this technology, Omega has a massive amount expertise and engineering at its disposal through the Swatch Group, and Rado has been making ceramic cases since forever.

 

CERAMIC BABY!!

Uses

The main use of zirconia is in the production of ceramics,[6][7] with other uses including as a protective coating on particles of titanium dioxide pigments,[1] as a refractory material, in insulation, abrasives and enamels. Stabilized zirconia is used in oxygen sensors and fuel cell membranes because it has the ability to allow oxygen ions to move freely through the crystal structure at high temperatures. This high ionic conductivity (and a low electronic conductivity) makes it one of the most useful electroceramics.[1]

News just in....

The black zirconium oxide ceramic dial, complemented by a matching ceramic 44.25 mm case with a brushed and polished ceramic casebody, features striking 18K white gold applied indexes as well as two blackened sub-dials that distinguish the timepiece from its legendary predecessor, OMEGA’s “Moonwatch”.

These two sub-dials are made possible by the innovative placement of the 12-hour and 60-minute counters on the same sub-dial at the 3 o’clock position, allowing a comfortable and intuitive chronograph reading.

There is a small seconds sub-dial located at 9 o’clock and a date window at 6 o’clock. The hour and minute Moonwatch-style hands are fashioned from 18K white gold, as are the hands found on both sub-dials; the central chronograph hand is rhodium plated and features a red tip for increased visibility of recorded seconds. Super-LumiNova coats the two dots at 12 and the hour, minute and chronograph hands ensuring that the wearing can read the time in a variety of lighting conditions.

Protecting this prominent dial is a box-form scratch-resistant sapphire crystal with anti-reflective treatment on both sides.

The matt chromium nitride tachymeter scale – among the most identifiable design features of the Speedmaster – stands out on the polished ceramic bezel. The two polished ceramic chronograph control pushers on the case function totally independently – accordingly, there is no risk to the chronograph mechanism as a result of inadvertent manipulation.

This unique timepiece is presented on a highly durable black Cordura® fabric strap complete with a black ceramic buckle. The timepiece is water resistant to 5 bar (50 metres / 167 feet).

Powered by the incredibly advanced in-house movement, the OMEGA Co-Axial calibre 9300, and equipped with a Si14 silicon balance spring, this Speedmaster is offered with a full four-year warranty.

The dark side of the moon
Engraved on the polished ceramic caseback in matt chromium nitride, above the bevelled scratch-resistant sapphire crystal, are the words “DARK SIDE OF THE MOON” – an appropriate tribute to this Speedmaster’s heritage and its bold black design.

Building upon our past’s great legends
With a design that recalls the same watch that accompanied astronauts to the moon on all six lunar missions, this model is a welcome addition to the family and one that upholds the bold Speedmaster name. It is sure to find a strong following among Speedmaster fans and watch enthusiasts who want to combine the impressive legacy of a remarkable chronograph with the best series-produced mechanical watch movement in the world.

 

It is a beauty but I fear with the ceramic case will be a very expensive piece - probably priced as if it were 18k gold.

 

Its definitely going to be a premium price, but I'm thinking it falls more into the same category as the Titanium Liquid Metals, which were about 25-35% more than standard stainless models off the top of my head.

 

AFAIK Ceragold is just gold with ceramic bezel and dial
