As a pioneering Chinese horological enterprise with decades of expertise, we have built a fully self-sufficient production ecosystem—and this movement exploded view shows it clearly. Every component here, from milled gears to calibrated springs, is designed and made in-house. Our vertical integration lets us control details like micro-tolerance gear teeth and multi-stage surface finishing, ensuring our movements meet global benchmarks and deliver reliable performance you can trust.

We produce millions of mechanical movements yearly, covering chronograph, automatic and manual-wind calibers, and this view reveals why they’re global favorites. You’ll see the layered structure: a sturdy main plate as the foundation, and intricate bridges securing key parts. These movements export to dozens of countries and serve as base calibers for international brands. That trust comes from visible craftsmanship—balance of structural stability and precision. Choosing a Sea-Gull-powered watch means relying on proven expertise.
