The formative years of the Singapore Watercolour Society were from 1970 to 1979. On 10 December 1970, SWS held its inaugural exhibition at the Victorial Memorial Hall, with then Minister for Culture, Mr Jek Yuen Thong, opening the exhibition. This was the first-ever watercolour medium exhibition in Singapore. The success of the first annual exhibition led to consecutive Annual Exhibitions from 1972 to 1980. During this period, SWS was also invited to participate in the regional exhibitions, namely Watercolour Society of Malaysia Exhibition and Taiwan Art and Educational Circle Exhibition in Taipei.
