19 jewels adjusted to 3 positions, manufactured from 1926 a total of 8,000 movements in 8 runs make up this grade. Model 3 open faced; 3/4 plate
movements of high quality, with double roller and patent micrometric regulator.
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 Christmas 1924 engraved 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.
Keystone type 2 cases were used on rotor-second dial movements, with chapter numbered bezel come in plain case back design.
Wadsworth Watch Case Co. supplied 14K gold filled and Star Watch Case Co. 18K gold filled. The majority are marked the Ball Model, with some of the
Star Watch cases unmarked. View case Images on Flickr.
