Found a Thin 12S Seth Thomas pocket watch. Would anyone have informatin on this model? Thanks for any help.

Using the data contained in Chris Bailey's Seth Thomas Watches 1885 - 1915 book, your movement appears to be a grade 326, 12 size, 3/4 plate, 7 jewel open face movement with nickel plates, timing screws, banking screws and a Breguet hairspring. This model appears in the 1913 S.T. catalog with a price of $6.00, but is not listed in the 1909 or earlier catalogs, so it was made late in the thiry year watch production period.
