From G-SHOCK, the watch brand that continues to evolve in pursuit of toughness, comes the OASIS OF DAY AND NIGHT series, inspired by an enchanting oasis under the blazing midsummer sun.

The base models are the GA-2100 with a slim octagonal bezel and the GA-110 with a rugged and robust form.

The OASIS OF DAY AND NIGHT series has a design theme of an oasis between day and night, and features a skeleton dial and vapor deposition indexes that resemble a sparkling water surface.

The sand beige-based model is inspired by daytime, while the dark grey-based model is inspired by a nighttime oasis, and the dial colors are different shades of blue and green to match.

Inspired by the oasis that can be found at the end of an adventure, this casual, easy-to-style seasonal color is perfect for marine sports and street fashion.
