If you're not sold on the idea of smartwatches yet, it could have something to do with the design. Some of the most popular smartwatches are black and boxy with unattractive bands.
Even some of the most fashionable and cute designs may not be to your liking. So, if you're thinking you'd like to have a smartwatch to track your steps, to listen to music, or get notifications from your smartphone, you may want to think "disk" instead of "watch."
Chronos is starting to sell a smart disk you can attach to your analog watch. (See photos next page.) The company says it's the world's thinnest wearable tech at less than 3 millimeters thick (0.12 inches). It'll be compatible with about 80% of watches.
The disk, which is wrapped in stainless steel, uses low-energy Bluetooth 4.0 technology to communicate with your smartphone. It vibrates and its LED lights light up, to alert you to notifications.
