About this deal

The GA-2100 is the slim, octagon-shaped G-Shock often nicknamed the ‘CasiOak’. It combines analogue hands with a small digital display in an all-black carbon-core case.

It has the toughness G-Shock is known for, including shock resistance and 200 m water resistance, but in a thinner, lighter case that fits under a cuff. Great as a do-everything daily watch or a gift.

RRP is £99 and it was £69.34 when we last checked, sold by Amazon EU with free delivery.
