The rumor mill has just churned out a couple of interesting bits of information regarding the so-called “iWatch.” As reported by The Wall Street, Apple’s long-rumored smart watch is going to have different versions and come equipped with a number of sensors.

The publication reports that the iWatch is likely to come in multiple screen sizes. It’s not specified, though, whether these will include the 2.5-inch measurement that was reported just yesterday by Reuters as a probable size of the device.

The Journal also reports that, according to people familiar with the matter, the iWatch will feature more than 10 health- and fitness-tracking sensors:

The new wrist device from Apple will include more than 10 sensors including ones to track health and fitness, these people said. Apple aims to address an overarching criticism of existing smartwatches that they fail to provide functions significantly different from that of a smartphone, said a person familiar with the matter.

These sensors are expected to work in conjunction with Health, the health-focused app announced by Apple at its recently concluded Worldwide Developers Conference.

As in Reuters’ earlier report, production of the iWatch is said to begin in two to three months at Quanta Computer, Apple’s longtime supplier for Mac computers.

With that production time frame, the Journal also echoes previous reports by Reuters and Re/code in stating that the iWatch could launch as early as October.
