Before turning professional in 1968, Jim Watt was a successful amateur boxer. He became the British lightweight champion in 1972 and 1975, and held the European title from 1977 to 1979. After entering the pro ranks, Watt defeated Colombian Alfredo Pitalua in Glasgow in 1979 to become the world lightweight champion. He successfully defended his title four times. However, Watt retired from boxing following the loss of his world lightweight title after being defeated on points by Nicaraguan, Alexis Arguello, at Wembley Stadium in 1981. He won 38 out of 46 professional fights and now works as a boxing commentator.
