Dots for the number face: There're two scale rings, bigger one is for clock time, smaller one is for alarm. On the bigger scale ring, there’re 4 small dots between each hour, each indicates 1 minute of clock time. On the smaller scale ring, each dot indicates 10 minutes for alarm. You can get an alarm accuracy via the smaller scale ring. Silent no tick-tock noise: Quiet sweep movement offers a second hand that moves in a continuous motion around the dial with NO TICKING, doesn't tick for restless sleepers. It is completely silent, there is no annoying ticking or winding. It's built very well, so it doesn't feel cheap. The second hand is definitely silent and it's very easy to set. Hands glow in the dark for a few minutes: Hold the clock directly under a light for a short time and the hands glows brightly for a few minutes. Reflective hands are easier to press the lightup button instead (if you can find it) and then you can read it better with blurry sleep filled eyes. The glow in the dark that fades as you go to sleep.
