This watch formed part of the Burton collection, see “The Watch Collection of Stanley H Burton Warts and All”. A rare early Tompion, no. 1303 (the circled dot representing a thousand), with subsidiary seconds. Until the application of the balance spring watches were not accurate enough for the indication of seconds to be useful. There are less than a dozen examples of Tompion's watches with subsidiary seconds recorded. The dial plate is stamped “SC” for the movement finisher whose mark is found on many Tompion watches as well as some by Daniel Quare and James Markwick. The mark might be for Sampson Crooke. This The quality of the movement was still appreciated enough 80 years after its manufacture to warrant it having a new dial and case made for it.
