The TAG Heuer Connected Calibre E4 has just been unveiled. The premium smartwatch now comes with a re-worked case, as well as several clever new features.

Connected Calibre E4 now comes in a smaller 42mm case, machined out of hardy Sapphire crystal, a slimmer metal case, and bezel. Of course, the sportier 45mm with ceramic bezel also features the same technical upgrades (battery life, for example, has been increased by 30%

TAG Heuer added an extra large crown for fingertip operation, and an altimeter – the pusher is also mechanical, just like one of the brand’s traditional chronographs.

The Connected comes with a greater variety of straps including leather, stainless steel, and rubber. Straps are more colourful, too – letting you chop and change them at will thanks to an easy-to-release clasp.

TAG Heuer also increased the number of watch faces available, adding a variety of heritage options to reflect TAG Heuer’s long-standing history of making timepieces.

Watchfaces include more information than ever before (which is where the smarts come in). Example functions include a five-hour weather forecast, activity times, and wellness-focused information.

The Connected Calibre Watch E4 has a new feature: a series of animated, on-screen “guided workouts” that target upper, lower or complete body muscles. The watch once again comes powered by the latest Google Wear software.

Like previous Connected watches, TAG Heuer offers a part exchange program for smartwatch owners who wish to upgrade to the most recent models. You will be able to trade the Connected watch back in with TAG to receive a discount on a ‘regular’ watch.

TAG Heuer will release the Connected Calibre 4 watches on March 10. Prices start at $1,800 USD.
