S. G. Jones is primarily known for his partnership with Abraham Patton from 1798 to 1813 that conducted business under the name Patton & Jones with interests in Philadelphia and Baltimore. Patton likely retired shortly after their last advertisement, dated January 8th, 1813, and Samuel Jones continued the business from Baltimore under his own name from 1815 to 1829. An advertisement the following year in 1816 is especially interesting due to the unusual phrase “particularly made”, that perhaps references movements like the one found in his watch number 1173, shown below. 
Samuel G. Jones, 93, Market Street. Has imported in the ship General Hand, Patent Lever and Detached Gold & Silver Watches, particularly made; also, Common Watches, ornamental Mantle & Eight Day clocks, Clock Movements, Clock Dials and a choice assortment of all the materials and tools, used by Clock and Watch Makers.  Federal Republican, 8 August 1816. (Whisker, 49) 

Similar S.G. Jones-signed watches are known, dated 1816 to 1818. All have Massey escapements and adjustable lever bearings (like a rack lever); however, are not conversions. Massey apparently installed his escapements in frames that were originally meant for rack lever movements. The evidence is Massey's EMP stamp on the underside of the balance table foot that indicates that Edward Massey himself fitted the escapement. 

More information on Jones and his affiliation with Edward Massey was published in the British Horology Times in June, 2016.

In addition to the watch signed S.G. Jones on this page, watches signed Leslie & Price, and Patton & Jones are also displayed on this website. In the late eighteenth century, Abraham Patton was in partnership with Isaac Price and renowned inventor Robert Leslie under the firm Robert Leslie, & Company. In 1796, Leslie divested his share and Patton and Price added partner Samuel Jones (S.G. Jones), renaming the firm Patton, Jones & Company. This firm ended with Price’s death in 1798.
