Specifically, precise mechanical engraving creates evenly spaced rays that extend outward from the center. As a result, the surface gains depth and dynamic light reflection.
We’re pleased to introduce this upgraded Seiko NH35 to our factory movement lineup. First, the NH35 is widely trusted for its reliability, durability, and excellent value. However, to meet growing demand for visual refinement, we’ve enhanced this proven caliber with decorative finishing tailored for open-caseback designs.
At the center of this upgrade, the main plate and bridges feature a sunburst (radial guilloché) pattern. Specifically, precise mechanical engraving creates evenly spaced rays that extend outward from the center. As a result, the surface gains depth and dynamic light reflection. Moreover, this premium visual effect is achieved without increasing movement thickness, therefore maintaining full case compatibility.
In addition, selected areas receive circular graining (perlage), while polished screws, refined jewels, and a signed rotor elevate the overall appearance. Together, these details deliver a clean, professional finish. Meanwhile, the movement retains its proven performance, meaning aesthetics are improved without sacrificing reliability.
From a technical standpoint, the movement includes 24 jewels, operates at 21,600 vph (3 Hz) with hacking seconds, offers a 41-hour power reserve, and supports manual winding. Consequently, it remains easy to integrate into most standard cases.
Finally, every unit undergoes strict factory inspection for accuracy, tolerances, and power reserve. As a full-scale OEM manufacturer, we also support customization such as rotor engraving, logo placement, alternative finishes, and stable-volume production with dependable lead times.
