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.

Owners widely praise the Aquatico Super Bronze Tritium Black Dial for its pleasing bronze warmth and high-quality CuSn8 bronze case, complemented by a ceramic bezel insert that reviewers consider an aesthetic high point rivaling luxury brands. The dial design is noted for its simplicity, gilt accents, and vintage lume, with snowflake hands adding a Tudor-style aesthetic, while BGW9 Superluminova provides an "icy blue glow" on indices, hands, and bezel. The watch features a dependable Seiko NH35 automatic movement and offers excellent value, with one owner reporting excellent quality despite a recent rotor replacement attributed to the movement rather than the brand. Owners are split on the bezel action, with some finding it stiff and others praising its aesthetics, and accuracy varies, with one sample running at +40 seconds per day and another experiencing issues requiring a rotor replacement.
