Ephraim Clark Pocket Watch
Ephraim Clark arrived from England in 1780 settling in Philadelphia. He was a distinguished maker as was his son, Benjamin, who learned the trade from his father. They worked together retailing clocks and watches and in 1793 succeeded the eminent Philadelphia clock and watchmaker John Wood. Wood headed the local guild, The Philadelphia Clock and Watchmakers Company (Harris, 699).
Benjamin's sons, Charles, Jesse and Ellis all worked in the business at times until 1811 when Ephraim retired. Benjamin and his son Ellis continued under the name B&E Clark from 1811 to 1845 and became one of the largest material dealers, including the largest suppliers of imported forgings and castings to Pennsylvania tall case makers (Gibbs, 24).

Several Ephraim Clark signed watches are known and all are beautifully finished. This example is engraved E. Clark Philadelphia, serial number 5968, and has a fusee and verge escapement, round baluster pillars, enamel dial and beetle and poker hands.
The silver pair cases have Birmingham assay letter for 1791-92 and maker's mark "IA" for John Adamson, Liverpool. They also have a King George III export duty mark that was used from 1786 to 1798 and indicates that the tax was paid on the silver cases (Priestley, 28).
Philadelphia watch paper by James Brearley located within the case. It reads, Ja., Brearley, Watch maker, No 115 No. Third St. Philadelphia.
Clark family watch papers are displayed for reference; Ephraim Clark's watch paper reads Ephraim Clark Watch & Clock Maker, The South East Corner of Front and Market Streets, Philad. Uncut early American papers like this one are rarely seen, circa 1780. Benjamin Clark, Clock & Watch Maker, No 1 South East corner of Front & Market Streets, Philadelphia. The third paper for Benjamin and Ellis is the same as the previous except for the added name. Read about American Watch Papers.
