Here come the smartwatches —
Samsung may be the latest company to leap into the emerging field of "smart," or Web-connected wristwatches. The company is planning to announce a new smartphone device that's worn on the wrist in September, according to a Bloomberg news report. No word on whether it might come in multiple colors, like the Samsung Galaxy Note phone.

Apple's rumored 'iWatch' —
Most current smartwatches rely on smartphone pairing over Bluetooth to get data and notifications. A long-rumored 'iWatch' from Apple could take the same approach as these rivals, or put more computing power directly into the device.

iPod nano watches —
Apple's sixth-generation iPod nano was a small, square touchscreen (it has since been replaced by the rectangular seventh-generation nano). Many fans immediately saw the potential to turn the iPod into a watch face, and companies such as Lunatik make kits that included mounts and slick straps.

Pebble —
The $150 Pebble waterproof watch has a black-and-white, e-paper screen, which can be customized with specially designed watch faces. It connects to iOS and Android smartphones over Bluetooth and vibrates to notify the wearer of incoming calls, e-mail, texts and other alerts. There are also downloadable music and sports apps.

I'm Watch —
The Italian-made aluminum I'm Watch is one of the pricier smartwatch options at $399. It comes in seven colors and runs the Droid 2 operating system. It connects to Android smartphones using Bluetooth to get texts and e-mails, check social networks, make calls and see calendar events.

Sony SmartWatch —
Another full color touchscreen device, the $130 Sony SmartWatch, also only syncs with Android devices. When paired with a phone over Bluetooth, it can receive notifications for e-mail, texts, social networks and calendars.

MetaWatch —
The MetaWatch has a retro-looking, black-and-white screen, but it can connect to the iPhone 4s and iPhone 5, in addition to Android devices. It's also a water-resistant sports watch that tracks pace and distance. The watch starts at $179 and is available with various colored bands or in black or white leather.

Motorola Motoactv —
The $269 Motoactv smart watch is marketed as a fitness tracker. It acts as a heart-rate monitor and pedometer, has GPS and an MP3 player. There are also a number of nonwrist mount options, including a handlebar strap, arm band and chest strap.
