Good looking durable clean lines 😎👍
Love this watch. Daily work watch. I work commercial HVAC and at times need to work in government high security no blue tooth allowed server rooms and or labs. This has all the other bells and whistles you need though. It is durable, I work with sheet metal and Sharp edge items all day and have not managed to scratch the crystal/ lens. Very easy to read analog and then it also has digital date and time. Easy to set if the directions don't make sense there are plenty of videos on u tube.

Great watch
Solid watch. Light and flat to wrist but with decent overall bulk.

My first watch in over 10 years. love it.
Pros - Love the look. The ruggedness you expect from G Shock. And so light weight I don't even notice it on my arm. Cons - It can be difficult to read in low light but the neon blue arms help. The negative readout on the LED screen looks great but makes it very difficult to read. But outside of the initial setup and maybe glancing at the date once a day I don't foresee needing the led screen much at all.

Nice watch!!!
Nice watch… bought it for my 12year old son. The size wasn’t too big for his wrist and the quality is excellent. The design is different but nice. The only problem is the light is not bright enough, but overall it’s a nice piece.
