I have set out grade 417 in 8 runs of 1,000 for easy reference, movements have ringed pattern demaskeening named Ball Watch Co. Cleveland Ohio.
The watches were adjusted and cased by The Ball Watch Co. to date little information about the exact production dates has been found, an early serial
numbered watch with 1926 inscribed on the case has been recorded. The dials are not recessed into the pillar plate and stretch dials were fitted and
choice of dial types and cases were advertised.
It looks like most of the movements have there original cases, although quite a few of the bows have been replaced.
Six types of cases have been used with these movements, 14 & 18K gold cases as yet case maker unknown. Keystone, Wadsworth and Star Watch Case
Companies made 14 & 18K gold filled cases all with there own case back designs.
Keystone Watch Case Co. type 1 and type 2 are 14K gold filled.
