Casio GST-B400

The Casio GST-B400 is praised for its sleek, sexy, and rugged design, with reviewers highlighting its well-finished metal case and bezel, large pushers, and Bluetooth connectivity at an affordable $320 USD. Owners generally appreciate its slimmer, lighter case design and bracelet integration, finding it a good size for smaller wrists and superior to some other models. However, several owners note that the mineral crystal is a compromise over sapphire, with one owner wishing for sapphire glass and a hardened case. The digital sub-dials and negative display are frequently cited as difficult to read in low light, and some users miss the presence of a second hand. On balance, owners and reviewers rate the Casio GST-B400 highly for its attractive design and G-Shock toughness at a competitive price point, despite some reservations about the display legibility and crystal material.
