Overview

The Sellita SW200-1 a is a self-winding movement that powers the watch through the natural motion of the wearer. As the rotor spins, it gradually winds the mainspring, ensuring a steady energy supply. Once fully wound, it provides a 38-hour power reserve, allowing the watch to run uninterrupted when not worn.

This movement features a date disc for added functionality, displaying the date clearly within the dial. Chosen for its precision, durability, and Swiss craftsmanship, the SW200-1 A delivers reliable performance, making it a preferred choice for both watch enthusiasts and manufacturers
