GST-B400 Versus GST-B300

The GST-B400 offers a slimmer size and lighter weight than the GST-B300, but it sacrifices some of the functions (such as a 1/100-second stopwatch instead of 1/1000-second and a 60-minute timer instead of 24 hours). Some advantages of the GST-B400 are that it has the reminder function (Bluetooth required) and the date format and language are adjustable.
