She was the artist who created the Claíomh Solais (Sword of Light) image used to commemorate the 50th anniversary of the Easter Rising in 1966.

She attended the Holy Faith Convent in Glasnevin and then the National College of Art and Design, where she was mentored by artist Maurice MacGonigal.

[1][3][4] Watters exhibited with the Royal Hibernian Academy between 1956 and 1965, alongside fellow artists William Leech, Louis le Brocquy, Harry Kernoff, Muriel Brandt, and her cousin Sean O’Sullivan.

[6] A year after her death, her husband organised a posthumous exhibition of 37 oil paintings at the Dublin Painters Gallery on St Stephen's Green.

Following the 1966 exhibition, Ó Tuairisc gave away most of Watters's work to family, friends, and acquaintances, effectively dissipating her legacy.
