This lower cost 7 jewel grade has its top plate pinned to pillar posts instead of being secured with screws; this saved labor and expense as screw manufacturing had not yet become highly refined. On the other hand, the pinned plates might have been an intentional distinguishing feature as these watches employed many other screws. The hairspring is also anchored in a brass stud on the plate under the balance cock on these watches, presumably hidden like this so the stud could be left unfinished and be less costly to produce. Although the C.T. Parker and P.S. Bartlett movements did not employ the same potance on the AT&Co grade, they did share the same design of ratchet, ratchet bridge, click, and click spring. The porcelain dial is plain with Roman numerals and seconds bit is not sunk. 18K C.J. & Bro HC #30 with eagle hallmark.
