A friend and I where discussing my SMPc 300M and I mentioned it has the Liquid metal ceramic bezel. He though only the Planet Omega had that feature. I remember the AD mentioning this is on more of the new SMP watches. I did some looking on line but no definitive answer was found. I did see on the Omega site they mention. Cut and pasted from their site
Redefining longevity in the watch industry
The OMEGA Seamaster Planet Ocean Liquidmetal® Limited Edition was the first timepiece to feature this stunning design element. Since its introduction in 2009, OMEGA has made use of this technology in several other timepieces in the Seamaster Planet Ocean 600M and Seamaster 300 collections.
The OMEGA Seamaster Planet Ocean Platinum marked the world premiere of diamond-set ceramic and sapphire, where the exclusive Pt850 Liquidmetal® alloy was used to fill the cavities in the ceramic bezel and then set with diamonds. The same alloy was used on the diving scale of the OMEGA Seamaster Planet Ocean Orange Ceramic, the world’s first timepiece to make use of orange ceramic.
So does the SMPc 300M count.
