Automatic Airmaster SS300 | 2 Styles

Automatic Airmaster SS300 

The S300 series is a classic watch with a high-beat 4Hz movement. It means that the second hand of the watch tics 8 times within a second instead of the normal one tic per second. On top of the hi-beat movement, the watch comes equipped with 5 ATM water resistance and Hardlex mineral glass. The simplicity of the dial and design makes the SS300 an extremely versatile all-around watch. If you are looking for a simple watch with a clear representation of time that doesn't require a battery to work, the Airmaster S300 series is definitely for you.

Maintenance of a hand wind watch

The Automatic Airmaster SS300 is an automatic self-wind mechanical watch, which means that it doesn't require a battery. Hand-wound watches need to be winded before use. After the first winding, the watch will keep moving and winds itself automatically from natural hand movement if used at least 8 hours during the day. 

How to wind a hand-wound watch? 

1. Pull out the crown
2. Screw the crown anti-clockwise to the current time
3. Push the crown back
4. Turn the crown clockwise until you feel the resistance (about 10-15 rounds)

Stop winding the watch when you feel the resistance. If you overwind the watch, the spring might break.
