Watson embraced En plein air painting, often capturing the effect of natural light falling to on to his subjects which gives many of his works an impressionistic style. His paintings Sunlight Reflected Upon a Wide Riverscape and Reflected Light are two examples which demonstrate his use of natural light.
His watercolour Across the River is in the permanent collection at the Tate Gallery. The Christchurch art gallery, Wellington art gallery and Brighton & Hove Museum & Art Gallery also have examples of his work.
In 1938 a memorial exhibition was held at Leamington Spa Art Gallery.
Harry Watson was a lifelong friend of Fred Appleyard.
