On September 28th, top actors gathered at the Banyantree Oasis outdoor swimming pool for the launch event of the 'OMEGA Seamaster Planet Ocean' collection. Attending stars included Ha Jung Woo, Jung Woo Sung, Gong Hyo Jin, Lee Dong Wook, Kim Min Joon, Jang Mi Hee, athlete Park Tae Hwan, and many more.  Actor Jung Woo Sung definitely stood out in the sea of black with his crisp white suit. The Seamaster ocean line was first launched in 2005 and is known for its ability to function 600m underwater as well as its stylish qualities.  The watch went through an upgrade in 2011 with new materials like ceramic and liquid metal.
