Phone calls on smartwatches have never really worked out well due to privacy: They’re like a speakerphone call in public. A new Kickstarter project called the HOT Watch has a solution and it blew through its funding goal in just 30 hours.

HOT Watch call

Is a smartwatch that allows for private phone conversations the holy grail of wearable devices? For many enthusiasts, the answer is yes, and the Hot Watch advertises exactly that capability: You can have a phone call through the ePaper watch but nobody else will hear the conversation.

The “secret sauce” is a patent pending technology called Hands On Talk (HOT), which bounces sound waves from the watch to your ear. How does it work? A speaker in the watch reportedly beams the sound off of your cupped hand, which you place near your ear.

Think of it like holding an invisible phone to your head. Here’s a video demonstration along with many more details on the watch’s development.

Although you can make and receive phone calls with the Hot Watch, it doesn’t require a separate phone plan because the phone functions are handled by your smartphone: The watch pairs with your handset over Bluetooth. In some sense, then, the wearable gadget is a unique Bluetooth hands-free device. But it also has other functions expected from a smartwatch: email notifications, texts, social networking support, weather and more.

The Hot Watch is currently a Kickstarter project but it has already blown through its minimum funding goal of $150,000 with 35 days left. At last check, the project topped $210,000. A pledge of $119 will secure your own Hot Watch, which will work with any handset that supports Bluetooth connectivity.

    Wonder how it works with hearing aids. Yeah, I know – cue the eyerolls.
    Too many years playing in a road band.

  3. I think this watch it tight! It’s crazy how much tech is in it! For a guy spending a lot of time on the phone on the go, this could make work one step easier! I think the HOT watch is legit.

    Here is another Smart-Watch campaign to check out. They have made $1,196,830 so far and have almost 10,000 funders.

    KREYOS: The ONLY Smartwatch With Voice & Gesture Control.

    1. Well.. I guess they used to be the only Smartwatch with Voice & Gesture control!

      All the same, I see the Kreyos and HOT Smart watch having two separate markets.. Kreyos is clearly more of a sports watch (i.e. it’s thicker, heavy duty and includes the lanyard), whereas the HOT is more of for everyday use. As far as I can tell HOT isn’t waterproof, just resistant, so if you’re looking for that, HOT wouldn’t be a good choice.

  5. The more I look at this watch compared to the other watches out their on the market; the more I love it! I believe it’s so much better tan any other watch out their. The features it has is unlike the other popular smart watches. I’m a fan of this watch!

  6. I found this exclusive interview about watch details on youtube. Check it out! http://www.youtube.com/watch?v=cQSpzv901To&feature=youtu.be
