According to Bloomberg, Swiss watchmaker Swatch is expected to release a new smart watch in the next three months. While this puts the product release at around the same time as the Apple Watch, the company appears to have confidence that the smart watch will perform well in the market. Why the confidence? It appears as though the smart watch will not have to be charged.

Why is this important? Most smart watches that use LED screens have to be recharged at least every other day. Rumors surrounding the Apple Watch have led industry analysts to conclude that Apple’s upcoming wearable will have to be recharged daily with “normal” use. “Heavy” use is expected to wear down the battery in just 3-4 hours.

It is unknown if the device will use an LED or OLED display, or something like a power-efficient eInk display like the Pebble, but a few things are known. The smart watch will use NFC to communicate with smartphones and other devices, and work with compatible Android and Windows mobile devices. The real question, though, is how the watch will not need a charge at all – even the efficient Pebble requires a charge every 5-7 days.

While this remains speculation, Swatch has filed patents related to powering a watch winder using solar cells embedded in the watch face. While it seems unlikely that a full LED screen would be able to be effectively powered by such an arrangement – solar cells are not efficient enough at such a small size – a more power efficient screen type may be used. In addition, Swatch said nothing about the smart watch being Bluetooth-capable, only that the smart watch would use NFC to communicate. Since this means that it is unlikely that the smart watch will be an “always-connected” device, it may reap significant power savings.
