Technical details of the watch is forthcoming. We have no idea how much RAM or onboard storage, nor do we know the battery capacity.
We do know it is has a nylon and aluminum 41 mm case, silicone strap and it further boasts heart rate tracking, untethered GPS, Google Assistant support, supports Spotify, NFC for Google Pay, and it is swim proof with water resistance up to 3 ATM (30 meters or about 100 feet).
Basically, it does what most smartwatches do. The key differentiating element for Kate Spade Sport Smartwatch would be the design. Even that, it would be just another smartwatch for your consideration.
