Last update 02/11/2012.
Grade 279,
21 jewels adjusted to 3 positions, manufactured from 1926 to 1930 a total of 17,000 movements in 23 runs make up this grade. Model 1 open faced;  3/4
plate movements of medium to high quality, with double roller and patent micrometric regulator.

Observations,
The movements come in a great variety of patterned demaskeening with the majority named Illinois Watch Co. and Illinois Watch, other named and
private labels make up the remainder. The grade look to be a continuation of grade 274 that ended production in 1926. As the Hamilton influence takes
over markings change from Illinois Watch Co. to Illinois Watch, concave winding wheels change to deco type and press fitted balance jewels were fitted.

Description,
21 jewels, oreide settings; adjusted to temperature; compensating balance; double roller escapement, steel escapement wheel; sapphire jewels; gold
strata, beveled center wheel; Breguet hairspring; patent regulator; safety pinion; concave polished winding wheels; demaskeened in bright pattern.
