Casio has expanded its G-SHOCK G-LIDE lineup with the GBX-H5600, the first watch in the surf-focused series to include a built-in heart rate monitor. The new model blends the tide and moon tracking that G-LIDE watches are known for with the fitness sensors of the G-SQUAD DW-H5600, wrapped in a lighter, see-through case aimed at surfers, swimmers, and everyday gym users alike.
The GBX-H5600 is currently sold through Casio’s own stores in Japan and the United States. An official India launch, along with Amazon.in and Flipkart listings, has not been confirmed yet.
Casio GBX-H5600: Design and Build
The GBX-H5600 keeps the classic octagonal 5600-series silhouette but introduces a translucent bezel that shows off the carbon fiber-reinforced resin case underneath. It comes in two colourways at launch, the GBX-H5600-1 in black and the GBX-H5600-2 in blue, both pairing the see-through top with a solid-colour resin band.
Key build details include:
| Specification | Detail |
|---|---|
| Case Dimensions | 51.1 x 44.5 x 17.3 mm |
| Weight | 47 grams |
| Case Material | Bio-based resin with carbon fiber-reinforced case back |
| Water Resistance | 200 metres (20 bar) |
| Display | High-definition MIP LCD with full-auto LED backlight |
| Charging | USB charging plus solar-assisted charging |
| Connectivity | Bluetooth Smartphone Link |
Casio has used bio-based resin for the case, bezel, and band, a material choice the brand says helps reduce environmental impact. The carbon fiber-reinforced case back also makes the GBX-H5600 around 12 grams lighter than the standard DW-H5600.
Heart Rate Monitor and Fitness Tracking
The headline feature of the GBX-H5600 is its optical heart rate sensor, paired with an accelerometer for step counting and distance tracking. This is the same sensor combination used on the DW-H5600, and training analysis is powered by Polar’s algorithm library.
The watch supports four dedicated activity modes:
- Running
- Walking
- Gym workouts
- Interval training
Data captured during these sessions feeds into training insights covering Running Index, Cardio Load, Energy Used, and Nightly Recharge. When paired with a smartphone, the watch can also use phone GPS for more precise distance correction during outdoor activities.
Sleep tracking is also included, powered by the same Polar-based analysis, along with support for guided breathing exercises through the connected app.
Tide Graph and G-LIDE Features
As a G-LIDE watch, the GBX-H5600 retains the tide and moon tracking that defines the series. The high-contrast MIP LCD displays a full tide graph on the main watch face, along with almanac data such as sunrise, sunset, and moon age.
Location data for the tide graph comes from two sources. The watch itself stores around 50 preset surf spots, while the Casio Watches smartphone app unlocks access to roughly 3,300 points worldwide, along with the option to set custom locations.
Smartphone Link and App Support
Pairing the GBX-H5600 with the Casio Watches app over Bluetooth enables:
- Automatic time correction
- Tide graph configuration for thousands of global locations
- Training log and life log syncing
- Detailed sleep and training analysis review
- Distance correction using smartphone GPS
- Phone finder and incoming notification alerts
Casio GBX-H5600 Price and Availability
Casio launched the GBX-H5600 in Japan at 44,000 yen (approximately USD 275) for the GBX-H5600-1JR and GBX-H5600-2JR models. The watch has since become available in the United States at USD 330 through Casio’s official G-SHOCK site.
There is no confirmed pricing or retail date for India at the time of writing. Casio India’s website currently lists the sibling DW-H5600 series but does not yet show the GBX-H5600. Once an official India listing goes live, pricing on Amazon.in and Flipkart typically follows within a few weeks of a Casio India launch.
Buyers who want a similar fitness-focused G-SHOCK available in India right now can check the current listing for the Casio G-SHOCK DW-H5600, which shares the same heart rate monitor and Polar-powered training features in a metal-bezel case.

Should You Wait for the Casio GBX-H5600 in India
The GBX-H5600 is a strong pick for anyone who wants a surf watch that doubles as a genuine fitness tracker, thanks to its heart rate monitor and Polar-backed training analysis. Since India pricing and retail availability are not confirmed yet, buyers who need a watch immediately should consider the DW-H5600, which offers similar fitness tracking hardware and is already listed in India.
