Age Estimate
Circa 1950-1955 based on the dial typography and the 'Antimagnetic' designation.

Fair to Good. Significant scratching and 'crazing' visible on the acrylic crystal; dial shows minor oxidation/spotting (patina); case lugs show wear consistent with age; strap is aftermarket and worn.
Value Estimate
$150 - $350 USD depending on the movement's health and the case material (higher if solid silver/gold, lower for plated).
