William Wallace Watt had been born in Partick in 1864, his grandfather a Shipowner and Merchant, his father a Merchant and all three, including his mother originally from Irvine. However, by 1871 the family had moved south of the Clyde, staying with well-to-do friends in Bellahouston, and by 1881 was staying in the Mount Florida area, where Willie was to remain for the rest of his life, and, of course close to both the first and second Hampden Parks. 

Meantime, however, it seems the young Watt from fourteen had been indentured to the Merchant Navy, coming out to work as a Clerk. And it was as such that he continued to work apparently humbly through and after his footballing career, after which he turned his attention to cricket, captaining Cathcart C.C. and becoming club secretary. Yet by 1911 Willie Watt was a Shipowners Manager, working for the major shipping company, J & A Allan, and living on Prospecthill Road and a decade later on Crosshill's Queen's Drive. And at both long-term homes, never marrying, Willie would stay with two of his sisters, both also unmarried. Indeed when he passed away at the latter address in 1943 at the age of seventy-nine it was one of those same sisters who would sign the death off. He was cremated at the Glasgow Cemetorium.
