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.

Owners widely praise the Undone Basecamp Stealth Steel for its unique Cali/waffle dial and blacked-out case, with the 40mm size wearing smaller due to short lugs. One owner reports the watch keeping great time, approximately 20 seconds off after a week. The crown's pull-out and push-in action lacks a sharp click, feeling more like pushing into rubber. On balance, owners rate the Undone Basecamp Stealth Steel highly for its distinctive design and wearability at the 40mm size.
