[1] His younger brother, Francis Watson (born on Saint Helena in 1860), also played first-class cricket, appearing in a single New Zealand domestic match for a West Coast team.
[8] An obituarist recalled: "I remember no innings which contained more good hits and fewer bad ones, than this of Mr Watson.
"[9] Watson's score of 175 stood as the highest total by a player on debut in first-class cricket in New Zealand until October 2017, when Brad Schmulian made 203 runs in the first innings for Central Districts in the 2017–18 Plunket Shield season.
[10] Canterbury totalled 381, setting a record for the highest total in New Zealand first-class cricket, and dismissed Otago for 77 (William Frith 8 for 18) and 72 (Charlie Frith 7 for 25) to win by an innings and 232 runs, a record victory margin in New Zealand first-class cricket at the time.
[12] In his last first-class match he again made the highest score, 82, when Canterbury beat Tasmania by one wicket in 1883–84.
