Right as Google's Wear OS is hitting its stride—now feature-rich with robust smartwatches that can go toe-to-toe with the Apple Watch—luxury watchmaker TAG Heuer has decided to ditch the operating system altogether for its latest Connected Calibre E5 smartwatch. It's also striking in its design, unlike any other smartwatch, with premium materials like a ceramic bezel, domed sapphire crystal, and snazzy band options.

A stainless steel polished case, black polished ceramic bezel with silver markings, and flat sapphire crystal also furthers the premium pedigree.
