The BIG IL book states the movement is a Grade 605, but does not include any discussion on it after Grade 604 on pg 139. Any thoughts - anyone ???

The Demaskeening is interesting

It is a pendant set, w/ looks to be a gold train, and made roughly 1916

The new book does show the grade 605. What are you wanting to know.

11,260 made in 17 Jewel open face.

Medium grade.

Was there more than one demaskeening used on the 16sz Stewart Special? All pendant set?



Thanks!!!

Jon,

Here's part of page 140 from the Illinos Watch Co. book by Meggers and Ehrhardt.

In the private lavel information on page 256 you'll find the grades that are lever set.

Here is a previous post showing my lever set Stewart Special: Illinois movement # 4010068 identification help

According to the Illinois Meggers and Ehrhardt Illinois Book Richard referenced, your very nice S/N2883004 Stewart Special is especially nice as it is #3 from the very first production run of 300 in this named grade 605 .

Apparently this named grade 605 had a total production of 2850 named Stewart Specials in the Serial Number range of 2883001-4118900 in the 1916-1922 time frame.

Furthermore these movements were finished with Gold inlaid two-tone, or regular Damaskeened Nickel Gold Filled engraved plates and Gilded or nickel polished Oval Head screws.

Yours is certainly an excellent example of this descriptive style.

Many thanks - Richard and David
