4r34 Movement

The Seiko 4R34 (branded) and NH34 (unbranded) movements have transformed the affordable watch market by making automatic GMT functionality accessible to microbrands and hobbyists. Previously, reliable automatic GMTs were either expensive Swiss calibers or less reliable clones; the NH34 now serves as the industry's "workhorse" for sub-$500 GMT watches VenezianicoReddit.
