The new design uses metal for both the strap and the face, with the main body boasting a brushed metal finish.
Beyond that it's precisely the same watch, packing in GPS, a 1.6-inch 320x320 LCD screen and IP68 rating, along with the ability to change the strap to any other 24mm design.
There's no word on price as yet, although the stainless steel Sony SmartWatch 3 release date has been set for later this month.
Sony also announced an update to it SmartEyeglass concept, with the new Attach! (exclamation mark not optional, apparently) module allowing you to transform any pair of specs into an augmented display, with sport and 'performance' touted as the early applications for this.
Another new prototype was announced at the same time: the Smart B-Trainer, which looks like a typical Sony MP3 player but now packs in more sensors to track the speed at which runners are shoving along.
With this info, Sony reckons it can provide voice coaching, music playback and even alter the song to give the runner the correct boost or cool down when needed.
As these are both prototypes we've obviously not got any idea on when they'll be released – but it's good to see that at CES 2015 we're finally seeing some good sport and technology combinations.
