- One of the greatest clock and watchmakers; to his work is due the supremacy of English horology in the 18c.; he made some of the first watches with balance-springs. He took Edward BANGER into partnership about 1701, then, apparently, worked alone, and took George GRAHAM into partnership about 1711. On his death, in 1713, Graham continued alone.
- The watches were numbered in three series, for plain, repeating and special watches, the numbering being continued from Tompion to Graham. Approximate dates and numbers are: with sig. Thos. Tompion to 1701 (No. 3292 plain, No. 203 rep.);
- Tho. TompionEdwd. Banger from 1701-8 (No. 3252-4119 plain, No. 196-290 rep.);
- Thos. Tompion 1709-13 (No. 4265-4312 plain, No. 359-392 rep.);
- T. Tompion& G. Graham 1711-13 (No. 4369-4543 plain);
- Geo. Graham from 1713 (No. 4669 plain, 393 rep.).
- Examples of his watches and clocks in most collections. Several one-year clocks (two in Buckingham Palace), including a spring clock striking hours and quarters. Many watches, long case and bracket clocks illustrated of Cescinsky& Webster (English Domestic Clocks, London 1914).
