Overview

The Sellita SW330-2 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, providing a power reserve of up to 56 hours when fully wound. This allows the watch to run for over two days without additional movement.

Chosen for its precision, durability, and versatility, the SW330-2 offers reliable performance with a GMT function, making it a preferred choice for travelers and watch enthusiasts alike.
