A Seiko (TMI / Seiko Instruments) automatic GMT caliber — the export-market designation of the Seiko 4R34 — that adds a 24-hour fourth hand to the NH35 / 4R35 base. It runs at 21,600 vph with about 41 hours of power reserve, hacks and hand-winds, and has become the default affordable GMT for microbrands.
