How It Works

What It's For

A silent vibrating alarm that wakes the wearer through vibration on the wrist rather than sound. This makes it ideal for:

  • Heavy sleepers who don't reliably wake to a normal alarm
  • Couples and roommates — it wakes only you, not the person beside you
  • Shift workers and students on different schedules
  • Hearing-impaired users who need a reliable, quiet wake-up

How the Two Buttons Work

With only two buttons, every function is reached by combining short taps and long holds, and by which screen (mode) you're currently on. The two buttons are usually:

  • MODE button — a short tap cycles between the screens (Time → Alarm → Stopwatch). While you're setting something, a short tap moves to the next field (e.g. from hour to minutes).
  • SET / ADJUST button — hold it to enter or exit setting mode; a short tap increases the value being set, toggles an alarm on or off, or steps through vibration levels.

Setting the Time

Step 1.  From the time screen, press and hold the SET button for about 3 seconds until the hour digits start to flash.

Step 2.  Tap SET to increase the hour to the correct value.

Step 3.  Tap MODE to move across to the minutes, then tap SET to set them.

Step 4.  Hold SET again (or tap MODE past the last field) to save and exit. The display returns to showing the time.

Setting an Alarm

Step 1.  Tap MODE until you reach the alarm screen (an “AL” indicator appears).

Step 2.  Press and hold SET for about 3 seconds until the alarm hour flashes.

Step 3.  Tap SET to set the hour, tap MODE to jump to minutes, then tap SET for the minutes.

Step 4.  Hold SET to save. Make sure the alarm is switched ON — a short tap of SET on the alarm screen usually toggles it on/off (the “AL” symbol shows when active).

Adjusting Vibration Strength

On units with adjustable vibration, tapping MODE (or SET, depending on the batch) steps through the levels — typically Mute, then Weak, then Strong. Set it strong for heavy sleepers.

Stopping or Snoozing the Alarm

  • When the alarm vibrates, a short tap of either button snoozes it — it returns after about 5 minutes.
  • To stop it completely, press and hold a button for about 2 seconds until the alarm indicator disappears.

Charging

Charge over USB. A full charge takes roughly 4 hours and lasts up to 10 days of normal use. Recharge when the display dims or the vibration weakens.
