The WIMM folks sell the WIMM One as a developer kit as its purpose it to get developers writing apps for the watch. These micro-apps will be available in the WIMM app store due to open later this year, each adding distinctive functionality for the watch.
The One is actually a small module that can be plugged into various accessories such as the rubber watch strap that comes in the box. It has a small transflective color touchscreen that is fully visible outdoors, and steps down to a low-power grayscale mode after a few seconds.
The module runs a version of Android that powers the watch functionality and runs apps that can be sideloaded from a computer. This uses the same cradle that charges the module by setting it into the small tray. Magnets pull the module into correct alignment for charging, and the cradle connects to the charger or PC via microUSB cable (included).
The WIMM One connects to the web via Wi-Fi, and to smartphones via Bluetooth. The web connectivity lets the module sync with the WIMM One account online, Google Calendar, weather service and other information. The Bluetooth connectivity lets the WIMM One serve as a Caller ID notification for most phones, and display incoming SMS messages with Android and Blackberry phones through a companion app for those platforms.
The WIMM One is $299 and while it is intended for developers it is well-designed and regular consumers will find it acceptable. Worn as a watch it is comfortable although a bit bulky, about the size of those iPod Nano watches.
I had previously tested the MetaWatch which uses a different approach to do many of the same functions of the WIMM One. The MetaWatch serves as an extra display for a smartphone via Bluetooth, and I found that very useful. Having a full Android device in the WIMM One is more useful, and the ability to add functionality through micro-apps is really nice.
