Timex will ship its Ironman One GPS+ smartwatch in November, starting at $399. The company is already taking orders at its Web site.
The Timex smartwatch price tag includes one year of mobile data service from AT&T, which means it can operate for data independent of a cell phone.
Phone-free text messaging and uploading of fitness performance data is included, according to online specs at the Timex site. Voice calling is not included.
Many smartwatches today, including the Gear 2 and Gear 2 Neo from Samsung, as well Android Gear devices, rely upon Bluetooth connections to a smartphone to access most applications. The Gear 2 includes a microphone for making calls and voice commands.
Even though it doesn't need a cell phone connection, the Timex device includes Bluetooth for functions such as streaming music (with 4GB of storage) to a Bluetooth-compatible headset.
The $399 model comes with GPS fitness tracking and a touchscreen display, while a $450 version adds a Bluetooth-ready heart monitor that is worn on the chest. Some of Samsung's smartwatches rely on a heart rate monitor on the back side of the watch that uses a laser light focused on the wrist. Some reviewers have found those readings to be inconsistent.
Timex said the mobile data service from AT&T will come with features that vary by market.
The Qualcomm Mirasol touchscreen on the device is advertised as always-on and capable of being read in sunlight. The battery provides eights hours of power in cellular-connected mode or four hours when music is also played.
Timex hasn't disclosed what operating system will run the smartwatch.
The Ironman One will rely on cloud-based services from Synchronoss, which also developed the watch's mobile applications and Web portal.
