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 clubmaker with Robert Thompson, 43 Hercus Loan, 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 Watt played in the Perrier Water Assistants' Tournament in October 1910 at Bushey Hall. The tournament was open to apprentices and assistants of professional golfers. The matchplay event was won by W.L.Ritchie who defeated Willie Watt in the final. Ritchie, assistant pro to James Braid won £21 and Watt received £10-10/-. Willie won the inaugural Scottish Professional Championship played at Dunbar in 1912. Also in the field were Willie Fernie, Andrew Kirkaldy, Ben Sayers, George T. Sayers, Robert Auld and Robert Thomson. Willie Watt (298) won £25 and a gold medal, his brother David Watt was runner-up (303) and £15. Robert Thomson from North Berwick finished on 307, and received £7.5/- while Ben Sayers finished 10th. Among the spectators was Frenchman Arnaud Massy. Willie was runner up in 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 Willie Watt had his best finish in the News of the World Tournament at Walton Heath. He reached the semifinals and was beaten by James Braid who in turn was defeated by George Duncan in the final.That year James Law the tenant at Archerfield persuaded Willie to return and look after the course.

At the age of 23 years, 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 February 1915 Willie was living at Easterbroom House, Dunbar where he enlisted to serve in the Black Watch regiment and offered himself for foreign service. According to Bernard Darwin writing in Golf Illustrated in April 1915, Willie Watt was refused permission to join the regiment on the account of a physical weakness. Later that year he was appointed the first pro at the Royal Automobile Association on their new course laid out in Woodcote Park, Epsom. Described as the first social clubhouse in the westend of London, organised on the same lines as the Athletic clubs of New York and Chicago, including a cricket ground and tennis courts. The golf course was unique being made up of three nine-hole courses which offered various 18 hole options.

To celebrate the opening a foursome match was played between Harry Vardon and James Braid against George Duncan and the new pro Willie Watt. It was reported that over a thousand spectators, including many soldiers in khaki watched the match. They enjoyed seeing Vardon and Braid playing together as they were normally on opposite sides. Their younger opponents Duncan and Watt where beaten 5 and 4, over 36 holes. In the crowd was the amateur Douglas Grant, a familiar figure around Monterey in California and a friend of George Turnbull from North Berwick while Pebble Beach was laid out in 1919.
