Story
The 'Sterling' model was marketed during the Roaring Twenties as a gentleman's essential technology, promising industrial accuracy in an elegant form.
Maker / Origin
Springfield's Illinois Watch Company was a titan of American horology, widely respected for producing heavily decorated movements that rivaled Swiss imports.
Condition & Value
Because the gold-tone-filled case carries negligible precious metal melt value, the watch's worth is dictated entirely by its mechanical vitality and the cosmetic purity of its dial. The case appears remarkably well-preserved with very little 'brassing' (wear through to the base metal) on the high points of the engraving.

Market Analysis
The market for early 1920s American pocket watches is highly stratified based on mechanical condition and original configuration. Direct sold comparables establish a strict floor of approximately $225 for non-running 'parts' watches or examples with severe case wear. Fully serviced, chronometer-timed examples retailed by horology specialists establish a definitive ceiling of $400 to $575. Without evidence of recent mechanical overhaul, this watch must be evaluated in the 'running but unserviced' lane. A comparable 21-jewel Illinois 'Sterling' sold for $300 on the secondary open market; considering the subject is a slightly lower-tier 17-jewel variant, an auction hammer expectation naturally falls into the $200 to $275 bracket, reserving the upper bounds for examples with pristine enamel dials and zero case 'brassing'.
Value Drivers
▲ Confirmed 'Sterling' grade 17-jewel mechanical movement, highly regarded for reliability.
▲ Original S.W.C.CO. case matching the era and production specifications of the Illinois Watch Company.
▲ Ornate engine-turned Art Deco case engravings and stylized dial typography.
▲ Absence of precious metal scrap value isolates the piece's worth entirely to its horological and aesthetic preservation.
Concerns
▼ Lack of verified service history significantly reduces peer-to-peer liquidity and necessitates an 'untested' valuation.
▼ Any 'brassing' (wear exposing the base metal core on the gold-tone-filled case) will severely negatively impact value.
▼ Hairline cracks in the dial enamel or oxidation on the hands immediately place the item toward the $200 floor.
▼ Lacks original presentation box or factory paperwork, typical for the era but standardizing it in the 'watch-only' lane.
Best Venue
Specialized vintage horology forums (e.g., WatchUSeek) or online auction marketplaces (eBay) with comprehensive macro photography of the movement and case markings.
Upside Potential
Professional servicing with timing documentation, or the revelation of a flawless dial under macro inspection, could elevate the piece into the $400+ specialty retail tier.
Authenticity Notice
Medium risk. While modern counterfeits of this model are rare, 'franken-watches' (marriages of mismatched movements, dials, and cases) are extremely common in vintage pocket watches. Verification of the S.W.C.CO. case serial (6813310) against 1920s production dates confirms original manufacturer configuration.
