For an automatic self-winding watch, "Automatic" means the movement will wind itself. The rotor attached to the movement rotates freely on the center axis, and these rotations act as a winding system that tightens the mainspring. When you move your arm, you can observe the rotor move through the crystal on the back of your Wryst Racer timepiece. As opposed to manual winding, this rotor, called "oscillating weight" in a more technical term, acts as if you were winding the spring manually. The natural movement of your wrist during your daily activities will cause this mass to spin and keep the movement running throughout the day. The Wryst SX1 can accumulate a power reserve of up to 38 hours, keeping the Swiss watch movement running overnight, even if you are not wearing it for a day. Once the mainspring is fully wound, and the watch is worn for an extended period, the rotor will continuously wind the mainspring, thereby topping off the power reserve. The reserve will ensure the mechanism runs even after the watch is no longer worn Most Reliable Swiss Mechanical Movement The strength and durability of your collectible high-end timepiece are essential. Wryst provides just that. The Racer SX1 holds a 26 jewels movement with a frequency of 28'800 A/h. If you decide to take your RACER off, the escapement will deliver power reserve for up to 38 hours fully wound. The main difference between quartz watches and automatic movements is that manual winding or the straightforward motion of the arm winds the mainspring. This SX1 also benefits from glowing luminescent hands and hour markers. Automatic Watches
