iOS 9.3 & watchOS 2.2 betas add ability to pair multiple Apple Watches with an iPhone
In a potential sign that new Apple Watch hardware could be around the corner, Apple's newly released iOS 9.3 beta gives developers the ability to pair multiple Apple Watches with an iPhone.

In the release notes for iOS 9.3 beta 1, Apple reveals that the Apple Watch app can pair with multiple watches at a time. This requires that the Apple Watch also be running watchOS 2.2, the first beta of which was also released on Monday.
Apple didn't explain why users might want to connect multiple Apple Watches to an iPhone, but it's easy to see why the capability might be advantageous from a developer's perspective. Connecting multiple Apple Watches to a single iPhone would allow a developer to more easily test their applications and see how they behave, without the need for multiple iPhones.
Of course, this ability would take on even more significance if Apple were to release a new Apple Watch with revamped hardware. Presumably, the ability to connect multiple watches to an iPhone would allow a developer to test their apps on faster second-generation hardware, alongside first-generation units.
It's unknown if Apple plans to offer multi-watch support to end users whenever iOS 9.3 publicly launches. But doing so could allow some of Apple's more affluent and fashion-conscious consumers to own multiple styles and colors for different occasions.

Hard to imagine why anyone would need the reason explicitly outlined to them.
Or, I don't want to ding my stainless watch when rock climbing so I'd rather have the aluminum on.
Also, battery life, so your watch didn't charge because it was slightly off-center on the charging base, grab your backup watch. Lame I know, but another reason to be able to pair with 2 watches.
Or how about wanting to wear your Watch Hermes -- with the exclusive Hermes watch face, and then switch to an aluminum Sport with the Mickey Mouse face to go to the beach.
Not a watch person huh? If you were you wouldn't question this for a minute. A move like this will actually drive sales among such affluent people as well. This was probably at the top of Jony Ives list to begin with. Or ditch the gold Edition watch when you are wearing silver accessories with an outfit, or alternate with the Rose gold Edition. Or alternate the gold Sport with the Rose Gold. Or the Space Black, or Space Gray with the silver watches ... and on and on ...
Should have been there from the start.
citing apple's wealth and suggesting they simply throw more warm bodies at a late project doesnt alleviate this problem, and can in fact slow things down. the mythical man-month:

Now they figured out how to make components small enough to fit in a watch, so the list of next device types is really endless...
Who said Apple ran out of ideas? They just built a headquarter bigger than Pentagon... Surely they are working on a few things - with margins of +60% and ridiculous growth potential from a platform of 700 mio existing customers...
