This samsung gear s3 classic is chunky becouse the round disply and tizen operating system and augments them with a raft of new sensors and a bigger, bolder design more closely resembles a classic analogue timepiece I know name is classic but the bigger part shouldnt be undeestated though and packing in the likes of gps, a barometer an altimeter and biger battery, samsung gear s3 classic is seriously chunky smartwatch. Its not going to suit every wrist
