Seiko
The no-date variant of the NH35 platform, eliminating the date complication entirely for clean dial designs without a date window. Identical in every other specification to the NH35 and NH36 siblings. Popular with modders and microbrands building minimalist or pilot-style watches where a dateless dial is preferred. The absence of the date mechanism simplifies the movement slightly but does not affect height.
