Seiko
Seiko's third-party supply version of the 4R35, sold to external watch brands and modders worldwide. Adds hacking and hand-winding over the 7S26 it effectively replaced. The NH35 has become the default automatic movement for watch modding and microbrand watches, thanks to its low cost, reliability, and wide availability of compatible parts including dials, hands, and cases in the Seiko-compatible format.

The community take
Owners talk.
Owners widely praise the Signum Cero's exceptional lume, satisfying bezel action, and distinctive dial design, with particular appreciation for the bronze case and green turquoise dial. One owner notes the watch wears a bit small and requires extra pressure to screw down the crown. The NH35 automatic movement powers the 39.5mm timepiece, which weighs a comfortable 47.25 grams with the buckle. Overall, owners rate the Signum Cero highly for its unique aesthetic and strong lume at the price point.
