What is the “Magic Lever” and how does it work?** The Magic Lever (pawl lever) is Seiko’s proprietary bidirectional automatic winding system introduced in 1959 . Unlike conventional Swiss-style systems that use complex reverser gears, the Magic Lever is a specially shaped double-ended pawl that picks up rotor motion in **both clockwise and counterclockwise directions** and transfers it efficiently to the winding mechanism . This results in faster winding with fewer parts—a hallmark of Seiko’s “smart simplicity” engineering philosophy . **3\. Which movements is this pawl lever compatible with?** This pawl lever is compatible with **Seiko NH35, NH36, NH37, NH38, and NH39** movements . These are all based on the same NH35 architecture, with differences in complications (date, day-date, 24-hour indicator, open heart/skeleton) . The Magic Lever winding system is shared across all these calibers . ## Why Choose SOFLY Watch Parts? * Fast worldwide shipping within 3 business days. * Competitive pricing on Seiko/Hattori calibers.

Is this a genuine Seiko/SII part? Yes, this is a\u00a0genuine Seiko (SII/TMI) factory part\u00a0made in Japan. The NH series is manufactured by Seiko Instruments Inc. (SII) and distributed by Time Module Inc. (TMI). The part number\u00a00831183\u00a0is the official Seiko designation for the Pawl Lever in the NH3 series technical documentation\u00a0. 2. What is the \"Magic Lever\" and how does it work? The Magic Lever (pawl lever) is Seiko's proprietary bidirectional automatic winding system introduced in 1959\u00a0. Unlike conventional Swiss-style systems that use complex reverser gears, the Magic Lever is a specially shaped double-ended pawl that picks up rotor motion in\u00a0both clockwise and counterclockwise directions\u00a0and transfers it efficiently to the winding mechanism\u00a0. This results in faster winding with fewer parts\u2014a hallmark of Seiko's \"smart simplicity\" engineering philosophy\u00a0. 3. Which movements is this pawl lever compatible with? This pawl lever is compatible with\u00a0Seiko NH35, NH36, NH37, NH38, and NH39\u00a0movements\u00a0. These are all based on the same NH35 architecture, with differences in complications (date, day-date, 24-hour indicator, open heart/skeleton)\u00a0. The Magic Lever winding system is shared across all these calibers\u00a0. Why Choose SOFLY Watch Parts? Fast worldwide shipping within 3 business days.
