The Singapore Watercolour society (SWS) was officially registered with the Singapore Registry of Societies. At fifty years old, SWS is now one of the oldest active societies promoting the use of water media in Singapore. Eight remarkable leaders have led SWS during its history, namely: Sim Kwang Teck, Chen Chong Swee, Khoo Ean Ghee, Gog Seng Hooi, Ong Kim Seng, Seah Kam Chuan, Dr Michael Lim and current President Seah Kang Chui. Each has made significant contributions to the water media art scene in Singapore.
