Casio G-Shock G-Steel Solar Powered Bluetooth Connected Stainless GSTB300E-5A

Casio G-Shock G-Steel Solar Powered Bluetooth Connected Stainless GSTB300E-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 & 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.
