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.

The community take
Owners praise the Manufaktur Waldhoff Atlas GMT as a "spec monster" for an office GMT diver, noting its Seiko NH34 movement, sapphire crystal, and 300m water resistance. One owner found the 41mm case too large for their wrist and sold it due to a preference for smaller case sizes. On balance, owners appreciate the Manufaktur Waldhoff Atlas GMT's impressive specifications at its price point, though case size can be a personal fit issue.
