Watt retired in 1800, the same year that his fundamental patent and partnership with Boulton expired. The famous partnership was transferred to the men's sons, [[Matthew Robinson Boulton]] and [[James Watt junior|James Watt, Junior]]. The long-time firm engineer [[William Murdoch]] was soon made a partner and the firm prospered.

Watt continued to invent other things before and during his semi-retirement. Within his home in [[Handsworth, West Midlands|Handsworth]], Staffordshire, Watt made use of a [[garret]] room as a workshop, and it was here that he worked on many of his inventions.<ref>Dickinson, ch. VII.</ref> Among other things, he invented and constructed machines for copying sculptures and medallions which worked very well, but which he never patented.<ref>Hills, vol. 3, pp. 234–37.</ref> One of the first sculptures he produced with the machine was a small [[Bust (sculpture)|head]] of his old professor friend [[Adam Smith]]. He maintained his interest in civil engineering and was a consultant on several significant projects. He proposed, for example, a method for constructing a flexible pipe to be used for pumping water under the [[River Clyde]] at Glasgow.<ref>Hills, vol 3, pp. 230–31</ref>

He and his second wife travelled to France and Germany, and he purchased an estate in mid-Wales at Doldowlod House, one mile south of [[Llanwrthwl]], which he much improved.

In 1816, he took a trip on the [[Paddle steamer|paddle-steamer]] ''[[PS Comet|Comet]]'', a product of his inventions, to revisit his home town of Greenock.<ref>Robert Chambers' Book of Days.</ref>

He died on 25 August 1819 at his home "[[Heathfield Hall]]" near Handsworth in Staffordshire (now part of Birmingham) at the age of 83.<ref>{{cite news |url=https://www.britishnewspaperarchive.co.uk/viewer/bl/0002762/18190829/024/0008 |title=Deaths. |newspaper=Wooler's British Gazette |date=29 August 1819 |page=8 |via=British Newspaper Archive |access-date=18 September 2024}}</ref><ref>{{cite news |url=https://www.britishnewspaperarchive.co.uk/viewer/bl/0002644/18190830/019/0008 |title=Died. |newspaper=The National Register |date=30 August 1819 |page=8 |via=British Newspaper Archive |access-date=18 September 2024}}</ref> He was buried on 2 September in the graveyard of [[St Mary's Church, Handsworth]].<ref>{{Cite web|url=https://www.freereg.org.uk/search_records/5818e459e93790de6a311110|title=FreeREG database: Handsworth St Mary burial, 2 September 1819: James Watt Esq, of Heathfield, age 83. |access-date=18 Sep 2024 |work=FreeREG |publisher=Free UK Genealogy}}</ref> The church has since been extended and his grave is now inside the church.
