## Description

This sporty and trendy watch is a perfect gift for New Year, birthday,valentine's day and so on -The watch has a calendar function: Day-Date, Bluetooth, Solar Powered, Stop Watch, Worldtime, Alarm

Review: Great, understated G-Shock - This watch has the rugged solidity of a G-Shock, but its dark octagonal face doesn't attract attention like some of the more flamboyant models. If you want your watch to catch people's eyes, this one isn't for you. However, I love its stealthy styling and useful Bluetooth integration (I find it quicker to set alarms via the app than fiddle with the buttons on the watch - although you do need to use a button manoeuvre to make the initial BT connection). The backlight is bright enough to easily see the digital display, at least, in the dark, although sometimes the analogue hands do get a bit lost.
Review: Perfect holiday watch - 200m Waterproof, updates time from phone so time is always right when travelling and solar so never needs to be opened to change battery. When you don’t want to risk damaging your smartwatch on holiday this is a great choice

### ⭐⭐⭐⭐⭐ Great, understated G-Shock
*by N***L on 31 July 2023*

This watch has the rugged solidity of a G-Shock, but its dark octagonal face doesn't attract attention like some of the more flamboyant models. If you want your watch to catch people's eyes, this one isn't for you. However, I love its stealthy styling and useful Bluetooth integration (I find it quicker to set alarms via the app than fiddle with the buttons on the watch - although you do need to use a button manoeuvre to make the initial BT connection). The backlight is bright enough to easily see the digital display, at least, in the dark, although sometimes the analogue hands do get a bit lost.

### ⭐⭐⭐⭐⭐ Perfect holiday watch

200m Waterproof, updates time from phone so time is always right when travelling and solar so never needs to be opened to change battery. When you don’t want to risk damaging your smartwatch on holiday this is a great choice

### ⭐⭐⭐⭐⭐ Amazing watch
*by M***D on 7 September 2023*

Wearing it right as I write this, super comfortable even for wider wrists lime mine. Looks great - even for a digital-analogue watch. Is slightly difficult to pair initially but after that it is very simple to use and incredibly accurate. The value for money is also incredible; especially when given the potential for modifying.
