Shock Resistance

Your G-SHOCK will keep ticking after a kicking. Tested against drops of up to 10 metres in height, and able to sustain hammer blows with significant force, these are seriously tough timepieces.

Water Resistance

All G-SHOCK models are resistant to water up to 20 bar/ 200 metres in depth, making them perfect for outdoor and even underwater wear.
