Overview
Maker 'LANCO' is clearly visible on the dial and the 15-jewel Swiss movement. The case interior is stamped 'SUPREME I. W. C. CO', identifying it as a gold-filled case made by the Illinois Watch Case Company.
Story
Lanco was a brand of the Langendorf Watch Company, a prolific Swiss manufacturer known for producing reliable, mid-tier timepieces. The movement is housed in a case by the Illinois Watch Case Company (I. W. C. Co.) under their 'Supreme' grade, indicating a quality gold-filled housing typical of the 1920s-1930s export market. The secondary market for vintage pocket watches is highly stratified.

Condition & Value
The dial exhibits significant age-related deterioration and patina, which is typical for the era but impacts the aesthetic appeal. Conversely, the intricate Art Deco geometric engraving on the case back appears to remain crisp.
Full Research
Sold comps, value drivers, and venue guidance pulled from recent auction results.
The secondary market for vintage pocket watches is highly stratified. While solid gold, highly complicated, or top-tier maker pieces command significant premiums, standard gold-filled examples from mid-tier Swiss makers like Lanco trade primarily as decorative or entry-level collector items. Art Deco styling remains popular, helping these pieces maintain steady, albeit modest, demand on broad online marketplaces.
▲ Distinct Art Deco dial styling and geometric case engraving appeal to period collectors.
▲ Gold-filled 'Supreme' case by I. W. C. Co. provides a durable, attractive housing.
▲ 15-jewel Swiss movement by Lanco establishes reliable mid-tier mechanical quality.
▼ Unverified running condition — if the watch does not run or keep time, the value drops to the lower end of the range.
▼ Unconfirmed crystal presence — if the glass crystal is indeed missing, buyers will factor in replacement costs.
▼ Significant dial deterioration limits the appeal to condition-sensitive collectors.
Best Venue
Given the typical market value for gold-filled Lanco pocket watches, a costly professional service would likely exceed the watch's resale value. It is best sold 'as-is' on a broad online marketplace like eBay or Etsy, ensuring you highlight the attractive Art Deco dial and engraved case while clearly disclosing its running status once confirmed.
Upside Potential
If the watch is confirmed to be in strong running condition, keeps accurate time, and retains an intact original crystal, it could reach the top of the estimate range or slightly exceed it in a retail setting.
