Haven’t used it yet. But the look and the quality is super awesome. I love the look of this watch.. I waited for 3 months to price to go down. I got this for 13k in sale.. ### ⭐⭐⭐⭐⭐ One off the best model within the 2100 range. *by on Reviewed in India 14 September 2026* The watch is on the pricer side.But it has everything thing that is important solar and bluetooth,since we do not get mulitband6 signal in india.You just need to connect the watch to the phone and it will sync the time and disconnect after few seconds if not using the app, which is good for people who do not want the watch to be connected all the time.It's a nice upgrade from the base model 2100. more comfortable to wear than the base model.I would suggest to get the positive display as it's much easier to see the time or other information on the screen compared to negative display. ### ⭐⭐⭐⭐ Casio G Shock GA-2100 Blue *by on Reviewed in India 23 September 2026* A beautiful watch with Bluetooth and Solar battery. But the watch I received did not produce audible beep alarm. The watch did not pass quality check before being sold.
