Jim was a shy and quiet spoken man, who allowed his club making to do the talking. His shop was very popular with local golfers and visiting dignitaries where they could arrange a golf lesson with Wilfred Thomson or Tommy Hoben, the last of the traditional North Berwick professionals. Jim Watt was an elder in the Abbey Church, and continued to work in his shop until he retired in his seventies. Many of his clubs are now highly collectable particularly the 'Watt Scareneck Spoon' from 1904 which is valued at over $600.

WILLIAM MARTIN WATT born 1889, was the youngest of the brothers and apprenticed as a club maker with Thomson at Musselburgh. Willie Watt was a member of Dirleton Castle Golf Club where he won many club competitions. One of the first professional tournaments Willie entered at the age of nineteen years was on the Burgh Course at North Berwick in July 1909. The field included five Open Champions; J.H. Taylor, Arnaud Massy, Sandy Herd, Harry Vardon, Willie Auchterlonie and two future champions in Ted Ray and George Duncan. Willie played well enough to gain the confidence that he could compete at the highest level. He won the Scottish Professional Championship in 1912, was runner up in 1909, 1914 and third in 1910 and 1911. His Scottish Championship Medal and the Croydon War Charity Medal which he won in 1915 are on display in the British Golf Museum.

Willie was appointed pro at Turnhouse G.C (1909-12) and he played in the Open Championship at Royal St George in 1911 and at Muirfield in 1912. That year he scored 72 at Carnoustie in the qualifying event for the prestigious News Of The World tournament at Sunningdale where he won £10. In 1913, James Law the tenant at Archerfield persuaded Willie to return and look after the course.

Willie Watt was selected to represent Scotland in the matches against England in 1912 and 1913. He reached the semi-finals of the PGA Championship in 1912, defeating Lawrence Ayton in the third round, but was defeated by James Braid who lost to George Duncan in the final. Willie gave golf lessons at Archerfield to Herbert Asquith, (Prime Minister 1908-1916) and as a reward, Willie and his family were invited to Downing Street to have tea with the Prime Minister.

In January 1915 Willie was living at Easterbroom House, Dunbar where he enlisted to serve in the Black Watch regiment and later that year he was appointed the first pro at the Royal Automobile Club at Woodcote Park in Epsom. The course was unique being made up of three nine-hole courses which offered various 18 hole options. At the opening of the new course a foursome match was played between Harry Vardon and his partner James Braid against George Duncan and Willie Watt. It was reported that over a thousand spectators, including many soldiers in khaki watched the match.
