Similarly, optical heart-rate tracking and GPS are both hugely power hungry, and Matrix says that it's had to work hard to optimize both. The compromise is that you won't be able to run the GPS for longer than 30 minutes a day, and that the heart-rate tracking will be set on intervals. Even that has required the size of the watches capacitor to be doubled, meaning that the PowerWatch 2 is pretty chunky.

The device is currently available for pre-order on Indiegogo, priced at just $200 for early birds, and -- if the company meets its deadlines -- will begin shipping by June. That deadline is firmer than you may expect, as representatives have said that they don't want to repeat the missed deadlines that plagued its first-generation watches.

Update 8/2/19 9:51am: Due to the positive response to the campaign, the company has added a higher-tier timepiece, the PowerWatch 2 Luxe. The limited run of 1,000 pieces comes with a shark mesh stainless steel band in either black or gold, as well as a plated warranty card.
