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

  • Long Shipping Times - Worth the Wait
Other than the long shipping times from the seller, having arrived 25 days from the date of purchase, the watch is in excellent condition. However, the watch packaging itself is made of loose cardboard, and the package it was shipped in was a simple bubble-wrap Amazon bag. Damage to the box is possible if the package was squished during the transit. The watch is easy to set up, durable, and functional. The resin strap is a bit stiff, but it adds to the rigidity of the G-Shock. The negative digital display is harder to see than the traditional positive display, but it's possible to read. The backlight is also really bright which adds to visibility in the dark. You could also use it as a makeshift flashlight if you're quickly grabbing something from a pitch-black room. ... show more

  • 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. ... show more
