His first international was against England, played at home at St. Helen's, and the match ended in a Welsh win.

Watts was reselected for the remaining two games of the Championship, an away loss to Scotland, and a crushing home win over Ireland.

Watts had joined the Wales team during their first 'Golden Age', and the loss to Scotland would be the only international defeat of his 11-match career.

Wales won all three Championship games, winning the tournament and taking the Triple Crown; and in beating France at the Cardiff Arms Park the team also took the first Grand Slam title.

Watts' final international campaign was the 1909 Home Nations Championship, which began with narrow wins over England and Scotland.
