Casio G-LIDE Quartz Unisex 50.9mm GBX100S-2D

Built for the ocean and inspired by it, the Casio G-SHOCK G-LIDE GBX100S-2D is the ultimate surf watch for those who live between the tides. Devoted to delivering the toughness and functionality demanded by the surfing lifestyle, the G-LIDE line offers summery materials and colour schemes with standout appeal.

Inspired by shimmering waves gleaming in the sunlight, the bezel combines gleaming stainless-steel components with glossy translucent resin — a dual-material design that looks as good as it performs. The vertically brushed finish and machine-bevelled edges on the steel bezel add a premium touch at an accessible price point.

This Bluetooth-connected G-LIDE model for ocean sports features advanced tide graph capabilities with more precise tide measurement predictions than other G-Shock tide models. It displays the actual height (in centimetres or feet) of high and low tides — information serious surfers can actually act on. Functions also include Moon Data, along with training features that measure distance travelled, elapsed time, pace, and more. A phone app lets you check tide information for any of a selection of major surfing spots around the globe.

The band is made of bio-based urethane with slits for a better fit and water and sweat runoff — a thoughtful, eco-conscious detail that doesn't compromise comfort or durability. The high-definition MIP LCD delivers superior visibility whether you're reading it on the beach or in the water.

With shock resistance, 200m water resistance, Bluetooth connectivity, step counting, and training logging all packed into a 50.9mm case, the GBX100S-2D is as capable as it is stylish — your perfect partner from shore break to sunset.
