Product Identity

The Casio G-Shock GA100A-9ADR is a new quartz sports watch built for adult men. Its yellow resin case and matching resin band use a buckle clasp for a secure fit. The round dial combines analog hands with a digital display in black with index markers.

Water Resistance Rating

This model is rated to 200 metres of water resistance, making it suitable for serious surface swimming and recreational diving. The fixed bezel and mineral crystal protect the movement from pressure and impact during aquatic activities.

Sustained Field Behaviour

Shock-resistant construction allows the watch to withstand repeated physical impacts during extended training or outdoor work. Quartz movement maintains accurate timekeeping without winding, while the full auto-calendar and world time functions track dates and zones reliably over long periods.
