Hublot Big Bang Referee Watch
Using the Hublot Big Bang Referee Watch, referees at the 2018 FIFA World Cup in Russia will be able to use goal-line technology to determine whether or not a ball crossed the line right from their wrists. It also has specialized functions for tracking stoppage time and substitutions, while regular fans get notified of every goal and access to a host of live stats. Built on Google's Wear OS and powered by an Intel chip, it clocks in at a hefty 49mm, with a titanium case and sapphire crystal protecting the 35.5mm round AMOLED display. Limited to just 2018 examples, it's finished with a black rubber strap.
