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.

  • The G-Shock GST-B300 returned to a more rugged G-STEEL style after the smooth look of the GST-B200. The GST-B300 is the only G-STEEL model with a front light button. The GST-B300 appears to be in the process of getting phased out in the U.S. and Europe, but stock may still be available at some retailers.
