Non-Battery Wrist Watches with Base Metal Cases, Automatic Winding

Automatic-winding mechanical wrist watches in base metal cases occupy the accessible end of the mechanical watch market — covering everything from entry-level automatics to mid-tier sport and dress watches — with Switzerland and Japan the leading US suppliers and Germany a notable third source. Unlike their precious-metal-cased counterparts in heading 910121, these watches are more broadly distributed through mainstream retail channels, making correct component classification especially important for importers sourcing movements, cases, and bands separately. The US schedule subdivides components across four jewel-count bands (no/one jewel; over 1 but not over 17 in two sub-series; over 17 in two sub-series), with separate lines for movements, cases, and bands at each tier. The automatic-winding designation — confirmed by the presence of a rotor mechanism — is the primary gate separating this heading from the manual-wind watches of 910229.
