NH35 movement: the mechanical heart of your A★Star watches
An automatic movement operates using the kinetic energy from your body. A rotor oscillates with your movements and continuously winds the mainspring. No battery — pure mechanics that can last for decades.
The NH35 is manufactured in Japan under rigorous industrial quality standards. It is one of the most reliable automatic movements in its category.
Its characteristics
- 24 jewels — friction bearings that reduce wear and prolong lifespan
- 72-hour power reserve — put it down on Friday, it's still running on Monday
- Controlled precision — we enforce -15 to +15 seconds per day during our tests
- Transparent sapphire case back — the movement is visible; the gears and oscillating rotor are observable at all times
Quartz is more accurate in the short term. The automatic movement has a soul that quartz does not — every beat is visible, audible, real.
A★Star — Born in the dark. Made to shine.
