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 talk.
Owners widely praise the San Martin BB NH34 GMT SN0054E for its excellent build quality, fit, and finish, especially considering its value, with many noting tight tolerances and craftsmanship. The watch wears comfortably, with one owner stating it fits like a Tudor BB58, and praise is given to the sapphire crystal, lume, and oyster bracelet, though a minor "12" marker alignment issue was noted by one owner. Some owners criticize the bracelet's pin-and-collar system, finding it rattly and preferring screw-link alternatives, while the pink dial is considered quirky by one commenter. The Seiko NH34 GMT movement is noted as a solid feature, and the watch is available for under $300 on sale. Overall, owners rate the San Martin BB NH34 GMT SN0054E highly for its outstanding value and solid craftsmanship at the price point.
