The low-end model will cost just $50 and feature black and white display similar to the Pebble, and it will be capable of keeping the watch going for about 1.5 weeks. Going up the ladder, there is a $100 model that will feature a 1.8-inch color LCD display, but the tradeoff there is that the battery life gets cut to just 2 days. The top option is slated at $129 and features a curved eInk display and metal housing; it is also rated at 1.5 weeks of battery life.
As far as functionality, Archos said the idea is to "extend" your smartphone, but didn't give too much detail. The watches will be able to connect to an Android or iOS device via Bluetooth LE and will offer customizable notifications, media controls, and more. It's unclear if there will be standalone apps for the watches, and no word yet on availability.
