The South Bend Watch Company Grade 429 is a 12-size manual-winding pocket watch movement of American manufacture. It was adjusted to isochronism for improved timing accuracy but did not meet railroad-grade standards. As an in-house caliber, it represents South Bend's own development work rather than a licensed or adapted design. Production ceased before the 1930s.
