Thomas Tompion (workshop)
Historical attributionPrecision clocks and watches of the early English school
History
Often called the father of English clockmaking, Tompion's workshop produced numbered clocks and watches of exceptional quality, collaborating with Robert Hooke and George Graham on escapement and balance-spring work.
Thomas Tompion established his business in London after an apprenticeship, first appearing in records around 1670. His workshop produced high-quality spring and longcase clocks alongside a substantial number of watches, often collaborating with scientific figures such as Robert Hooke. Following Tompion's death in 1713, George Graham assumed control of the workshop and continued the established production methods.

Key models
- one-year clock
- Commissioned by King Charles II for the Royal Observatory in 1676, these precision clocks were designed to be wound only once a year.
Major innovations
- Tompion was responsible for the systematic application of serial numbers to his clocks and watches.
- Early adoption and refinement of the balance spring in watches
- The workshop pioneered the early adoption and refinement of spiral balance springs in English watchmaking.
- He collaborated with Edward Barlow and William Houghton to develop an early precursor to the cylinder escapement.
Known markings
- 'Tho: Tompion Londini Fecit'
- Workshop serial numbers
- The workshop used specific signatures that varied according to the active partnership and year.
Serial numbers
Tompion's numbering is a key authentication tool but has been widely imitated; attribution requires physical examination and documented provenance.
Collecting significance
Essentially a museum-level field. Signed movements without provenance should be treated with caution.
Identification and dating notes
- Signatures on the dial plates can help date items to the period of the Tompion and Banger partnership.
Where sources differ
- Founding date: this record gives “c. 1671 (Clockmakers' Company)”; a cited source gives “1674”. The record is kept until the difference is resolved from period documents.
