is ther a web site to find size and jewel count on Seth Thomas watches all I have the serial #
170726 for the watch from potential seller .

www. post a picture here for eric.com is all I know.

all I have the name and serial # and that the watch is in silver case

It is a 6 size model 16 with anywhere from 7 to 17 Jewels.

A few of these were made with spread dial plates to look like 12 or even 16s Very Thin appearing watches.
Value would be in case only unless much, much more is known.

Thank you Dave.
size 6 is not my thing.
