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.

Sheffield 1A owners praise its superb quality, sturdiness, and value, noting it feels more substantial than a Seiko 5. The blue dial is highlighted as a positive feature. One owner flagged expensive shipping fees as a drawback, and another suggested the bezel action could be crisper. Overall, owners consider the Sheffield 1A a no-brainer for its affordability and quality.
