Community
Owners widely praise the Casio GST-S100G for its appearance, noting it is more attractive in person and especially in sunlight, with some appreciating the gold accents. The solar charging function is highlighted as remarkably resilient, with multiple owners reporting the watch revived after years of inactivity simply by being placed in sunlight. One owner describes the band as extremely well-made and comfortable. The Casio GST-S100G is considered a beautiful watch that deviates from typical G-Shock aesthetics. One owner reports that the digital and analog time displays on their 7-8 year old GST-S100G do not match. Another owner noted their GST-S100G-1A displayed "CHG" in sunlight, indicating a depleted and uncharging battery after a month of sun exposure. On balance, owners rate the Casio GST-S100G highly for its striking aesthetics and exceptionally durable solar charging capability, which allows it to revive even after extended periods of disuse.
