G-STEEL
GST-B300 Series
GST-B300E-5A
A model with a rugged style based on a G-STEEL model that uses the carbon core guard structure from G-SHOCK, which continues to evolve in the pursuit of toughness. A model covered with a rugged and playful design typical of G-SHOCK, with a disc dial that shows the current function mode and remaining charge at the 6 o'clock position, and ruggedly designed front button. Additionally, the round digital graphic at the 1 to 2 o'clock position, which is asymmetrical with the disc dial, achieves both functionality and design, together with the digital LCD at the 12 o'clock position. The model comes with a resin band and a cloth band in addition to the stainless steel band, so wearers can enjoy switching them.
