Chronos turns any wristwatch into a smart one

Turning a classic wristwatch into a smart one is not something new, but most accessories that can accomplish this goal are bulky or simply lack most features one would expect from a smartwatch. Although Chronos does not offer weeks of autonomy, it is very easy to use, works with most watches, and also has a software companion that works with both Android and iOS devices.

The Chronos disc is under 0.21 inches thin and has less than 1.3 inches in diameter, so it can be easily used on more than 80 percent of watches sold today. Its case is made of stainless steel and has been rated IP67 for protection from the elements. Chronos has Bluetooth 4.0 LE connectivity and features wireless charging. The battery life is only 36 hours, but a full charge only requires 30 minutes. It uses haptic vibrations and LED lights for notifications, also featuring an accelerometer.

The accompanying app allows Chronos' users to manage notifications, sync activity data, as well as to personalize the taps and gestures used to control the phone's functions (for example, one can double tap the watch to silence incoming calls).

Pre-orders are open for $99 USD a piece, but the price will go up to $129 USD once the pre-order period is over. Two Chronos discs can be purchased for $189 USD, but two bundles that include watches are also available ($169 USD with an Elliot Havok, and $389 USD with a COURG).
