Story
Amko was one of many mid-century private labels that utilized robust Swiss movements to provide precise, affordable timepieces to the growing middle class. The prominent labeling of shock and magnetic resistance on the dial reflects the post-WWII race to make timepieces durable for everyday professional wear.
Maker / Origin
Unattributed · Swiss-made movement; Amko (Swiss/American Private Label)
Condition & Value
Because professional servicing often exceeds the watch's intrinsic value, verified running condition and a clean, original dial are the absolute primary determinants of market appeal. The dial shows a light, even spotting known as 'patina,' which many collectors prefer as it proves the watch's age.

Market Analysis
Valuation for generic, private-label vintage watches is driven almost entirely by mechanical condition and dial preservation rather than brand-driven premiums. Primary sold comparables indicate a strict retail ceiling of $150 for fully serviced, aesthetically restored Amko watches. However, the auction and peer-to-peer collector markets present a more grounded baseline. A running Adria/Amko 17-jewel example recently sold for $80, and similar unserviced vintage examples often clear around $100 on platforms like Yahoo Auctions. Our fair market value range reflects an unserviced but intact auction outcome for a watch-only package. Should the movement be seized, heavily water-damaged, or the case exhibit severe plating loss ('brassing'), the value defaults to a $20-$30 parts-only floor.
Value Drivers
▲ Presence of mid-century dial text ('Inc Bloc', 'Antimagnetic') confirming original configuration.
▲ Reliable 17-jewel Swiss ébauche mechanical movement.
▲ Vintage aesthetic appeal to entry-level horology enthusiasts.
Concerns
▼ Unknown service history (professional servicing costs often exceed the intrinsic value of private-label watches).
▼ Unverified metal case material (likely base metal prone to 'brassing' or plating wear).
▼ Lack of original box and papers (standard for this tier, but limits upside).
▼ Absence of brand prestige compared to heritage luxury makers.

Upside Potential
Verified, recently serviced running condition with a clean timegrapher readout.
Authenticity Risk
Risk level is low. Counterfeits of obscure mid-century private-label watches are virtually non-existent, though buyers should evaluate for 'Frankenwatch' traits (mismatched hands or replaced non-era-correct crowns).
