Watch CASIO GBA-900-1AER G-SHOCK bluetooth G-SQUAD — men's watch, shock-resistant, digital-analog

CASIO GBA-900-1AER G-SHOCK G-SQUAD is a men's shock-resistant watch with combined digital and analog display and Bluetooth Smart connectivity. Designed for active use, the watch offers automatic smartphone time sync, step tracking with lifelog calculation, and robust build quality including mineral glass, a resin case and resin band. Water resistance to 20 bar and a two-year battery life make it suitable for demanding everyday wear and sports activities.

Advantages

The watch features energy-saving Bluetooth Smart for wireless connection to a smartphone, automatic time adjustment, and a Super-Auto LED Light that illuminates the display when the ambient light fades. A 3-axis accelerometer counts steps and the lifelog function estimates calories and distance. Additional benefits include shock resistance, a second time zone, multiple timers and alarms, lap memory for up to 50 records, and practical functions such as phone finder, incoming call display and hand moving function for clear visibility of digital displays.

Suitable for

• Sports and fitness tracking (running, training sessions)
• Outdoor activities and everyday wear
• Frequent travelers needing a second time zone
• Users who want smartphone-connected features (notifications, phone finder)

How to use

Connect the watch to your smartphone via Bluetooth Smart to enable automatic time updates, incoming call notifications and the phone finder function. Use the mode and function buttons to access stopwatch, timers, alarms and lap memory; the hand moving function temporarily moves analog hands aside to view digital displays. The Super-Auto LED Light activates when ambient light is low and you turn your wrist. For step tracking and lifelog data, wear the watch during activities so the built-in accelerometer records steps and the watch calculates estimated calories and distance.

Usage recommendations

To maintain performance and water resistance, avoid pressing buttons while the watch is submerged. Clean the resin band and case regularly with fresh water after exposure to salt water or sweat. Replace the battery approximately every two years or have it serviced by an authorized service center to preserve functionality.
