In 1876 Watsonians adopted the maroon and white colours it wears today and two years later the club moved to Myreside, named after a local farm of the day. In 1877 the club became a member of the Scottish Football Union (which became the SRU in 1924). Watsonians won their first Scottish Club Championship in the season 1891/ 1892, but their greatest period of dominance came between 1908 and 1914 when they won the championship a further five times. After relegation in 1989 the club relaxed its membership rules and having gone undefeated in Division II they won promotion back to Division I in 1991. After returning to Division I Watsonians challenged regularly for honours until, in Season 1997 / 1998, they regained the Scottish Championship title. Since John Tod played for Scotland in 1884 Watsonians have fielded over seventy Scottish internationalists, including five Scotland captains and seven British Lions.
Watsonians have had key roles in all three of Scotland’s Grand Slams to date. In 1925 AC Gillies played in three matches. In the game against France he scored one try and kicked two conversions, while in the game against England he converted a try with a superb kick from the touch line to help seal victory. Against England in 1984 centres David Johnston and Euan Kennedy both scored tries en route to Scotland’s first Grand Slam since 1925. Gavin and Scott Hastings played in every game of Scotland’s successful Grand Slam in 1990. In the never to be forgotten final game against England it was Gavin’s kick through that set up the deciding try, scored by Tony Stanger, while Scott made an outstanding try-saving tackle on Rory Underwood.
More recent Watsonian Scottish internationalists include Tom Smith, Duncan Hodge, Cameron Mather, Marcus Di Rollo, Jason White, Chris Cusiter, Kyle Traynor, Steve Lawrie and Fraser Brown.
In recent years many Watsonians have been capped for Scotland Sevens including Colin Gregor, Andrew Turnbull, Mike Fedo, Andrew Skeen and current player Jack Ferguson. A number of other current first XV players have also trained with the squad.
Watsonians have also a good tradition of providing internationalists for the Scotland Women’s side.
