Great looking smaller casioak. I think the styling is really geared for women, which is fine since I got this for my wife. This wears smaller than the indicated dimensions, so if you're interested, try checking in store first on how it really wears. As for the seller, they did a really good job of packing it so it got to me in great shaped (wrapped in so much bubble wrap I actually had to use a swiss knife to cut through it).

Better then expected

This watch looks way better in real life. Orange parts look almost like pink gold which gives very original effect in combination with the robust, black envelope. It is very pleasant to wear and quite easy to set up without the manual. It took me just 2 minutes to figure it out.

Bought this as a gift

Bought this as a gift for my partner as she needed a casual weekend watch and she absolutely loves it. It's every bit as tough as the full size G-Shocks but in a much smaller case. The colour is lovely, particularly the dial. Pictures don't do it justice.

Casio G Shock Mid Size Neo Pink Strap Watch
10 July 2021

Comes in a lovely presentation box. Fits like a dream, like to have the strap looser on my wrist. I would say the colour is more of a deeper pink rather than the colour shown. Had a number of comments on the unusual colour of strap and matching face. Didn't take long to set up at all. I particularly like the light for night time viewing and the hands show up very well in the dark as the gold coloured markers do stand out. All in I like thefeatures and functions of this watch. I replaced a white strap Casio which was a few years old but the strap had discoloured. I find them easy to wear and easy to use.

Cheap and light
27 January 2024

owned a few baby g's and familiar with this brand. this watch is cheaply made. watch is quite light and straps are thin feeling. also feels awkward due to having a small wrist so that was the second factor in returning the watch. the first is the cheaply made, almost like a toddler's watch does not justify the price! more like a $25 max watch no more!

Great watch , subtle lovely
7 April 2024

Great watch , subtle lovely merging colours top quality you expect from Casio. I have just bought a GG B100 from a independent jewellers because it was on sale for £75 cheaper than original RRP. Another great g shock.

The quality of the watch
23 January 2024

The quality of the watch turned out to be very poor. The white strap changed its color to pink within 1 week of buying. I am very disappointed as I did not expect it with this brand name.The watch has lots of technical issues it can't set its time on zone and since the purchase, I Could not set a proper time on the watch.I tried to contact customer care but no help.The looks of the watch are decent with a bit of uncomfortable straps which makes it difficult to wear sometimes. But due to time setting issues and quality, I never could wear it.

Too complicated to use
27 June 2024

Lovely looking casual watch but can't figure out how to set the time! My husband has had a GShock for years snd we can't change the time on it. I hoped this one would be different but it's not. Why are GShock watches so complicated to use!?
