The color change is just the latest sign Apple's pushing forward.
But it's a good moment to remember this signals Apple's continuing to push forward on its wrist-worn device, which was updated in September last year with features like GPS and better water proofing. Apple hasn't said how many of its Apple Watches have been sold, though it has said the device hit a new sales record over the holidays. The company didn't respond to a request for updated figures.
So things are looking up for Apple. Which is why even tiny news like the new-gray Nike-inspired Apple Watch is probably a good sign.
