article: The US company says the "limited edition" Toq is designed to showcase its new technologies rather than compete with its other products. Qualcomm is best known for making processors that power smartphones. However, one analyst suggested the device was too bulky to appeal beyond a niche enthusiast audience. The $349 (Â£215) gadget is being made available via only Qualcomm's website to US customers, and the company said it was "unlikely" it would sell the watch elsewhere. The Toq is designed to be paired with any smartphone running Android 4.0.3 or higher. It allows its owner to receive and send text messages, manage reminders and view other information - such as weather forecasts or stock prices - obtained via their handset. There is no software store for the watch itself, but existing handset apps can be adapted to send details to its display and activate a vibrate function. In addition it can be used to accept or reject calls, and control what music is being played from the linked phone's library. The company says that the watch's key innovation is its use of its proprietary Mirasol technology. Rob Chandok, president of Qualcomm Interactive Platforms, described this as being similar to the e-ink displays commonly used by e-book readers and another smartwatch - the Pebble - but better. "In addition to the fact it offers colour, the refresh rate of Mirasol can be 30 frames a second, which allows you to build a touch interface," he told the BBC. "That's tremendously important when you are trying to offer some of these experiences. "In an e-ink display you can't refresh the screen fast enough to follow the finger." Mirasol is significantly less power-hungry than the OLED tech used by Samsung's Galaxy Gear watch, meaning that unlike its rival, its screen does not have to turn itself off when angled away from the user's face to extend battery life. Sony's Smartwatch 2 does offer an always-on LCD display - however, it requires the user to switch on a backlight in dim conditions. Although Qualcomm suggests the Toq's lack of an on/off switch makes it the superior option, Mr Chandok acknowledged that the Toq display's graphics were not as vibrant or crisp as the alternatives. "But we've got other versions of Mirasol in the pipeline that are going to have a better colour gamut and vibrancy," he added. Qualcomm has also included three other technologies it has developed that it hopes will attract the attention of manufacturers: Mr Chandok said "tens of thousands, but not hundreds of thousands" of the watches were being produced, adding that its appeal was likely to be limited to an "early adopter" crowd. "We would consider making more if the demand were high," he said. "But our preference is for our partners to bring out products [using the new technologies] in the next six months, and we're working hard with a few people to do that." He declined to name the companies involved, but did reveal that in theory the Toq could be made compatible with Apple's iPhones. "We limited the spend
summary: Qualcomm has released a smartwatch that it says can last days between recharges despite the fact its touchscreen display is always on.
