  • Very good watch and alarm. Works very well! Adjustable fit and easy to set the time. It works as both a watch and an alarm, and it isn't too bulky or too slim. Easy to charge, and the battery lasts a long time. I charged it for around an hour and it has yet to die. I recommend this product.

    Get it between - and -.

    Phone alarms either blast the whole room awake or get snoozed until you're late. Onyx fixes both problems. It's a slim wristband that vibrates against your skin at the time you set. The alarm is silent to everyone else, and you feel it directly on your body instead of hearing it across the room. You can finally keep your phone out of the bedroom and still get up on time.

    Silent Vibration Wake-Up 

    Onyx wakes you with a firm vibration right against your wrist instead of a loud ringtone. Because the alarm is felt instead of heard, only you notice it, and your partner, baby, or roommate keeps sleeping. You won't jump awake to a blaring phone or start the day stressed. It works for early work shifts, 5am gym sessions, and new parents who can't risk waking a baby they just got back to sleep. You get up on time, and everyone else gets the rest they need.

    3 Independent Alarms 

    You can program up to 3 separate alarms, each at its own time. Set a main wake-up, then a backup a few minutes later as a safety net in case you switch off the first one half-asleep. Use the third for a midday nap, a medication reminder, or school pickup, silently, even in a meeting or on a train. Instead of stacking 10 phone alarms that wake the whole room, you get a simple setup that's easy to trust. It helps heavy sleepers and chronic snoozers stop being late.

    20+ Day Battery

    Onyx does one job and does it well, so one charge lasts 20+ days. That solves the biggest problem with using a smartwatch as an alarm: you have to charge it at night, which is exactly when you need to wear it. Just snap on the magnetic charger for about an hour, and you're set for weeks. It's perfect for travel, business trips, and anyone who doesn't want another device to charge every night. Wear it, set it, and forget about it.

    Sound Wakes the Room. Touch Wakes Only You.

    A phone alarm sends sound through the whole room, so everyone hears it, and your brain learns to tune it out. Onyx sends a vibration straight into your wrist. It's silent to everyone else, and it's hard to ignore because you feel it on your body.

     What Customers Say

    • "My husband finally sleeps through my 5am alarm"

      I work early shifts, and my phone alarm was waking him up every day. Now I just feel a buzz on my wrist and get up. The band is soft enough that I forget I'm wearing it. Setup took about two minutes.

      Jacob Griego

    • "Battery lasts forever"

      I charged it for about an hour when it arrived and haven't needed to charge it again for weeks. It also works as a watch during the day. It's not too bulky and not too thin. I'd recommend it.

       Mama Bethany

    • "Great for a heavy sleeper"

      I've slept through every alarm clock I've owned. The vibration on my wrist is a lot harder to ignore than a sound across the room. I set two alarms ten minutes apart as a backup, and I haven't been late since.

      Scott Smith

    • "Simple and does the job"

      There's no app and no notifications, just an alarm on my wrist. I like that my phone stays in the kitchen now. I took one star off because the band could come in more colors.
