The media could not be loaded. Realmente soy fiel a Casio de toda la vida y cada reloj que he arquirido con los años me ha solprendido el diseño la tecnología pero con este hermoso reloj me ha solprendido lo increíble y exacto que es su diseño unico y practico para cualquier activida sea para trabajar o salir de gala luce Realmente genial. Lo recomiendo a todos I am really faithful to Casio for life, and every watch I have purchased over the years has given me the design, technology, but with this beautiful watch I have been surprised by how incredible and accurate its unique and practical design is for any activity, whether it is to work or to leave the gala, it looks really great. I recommend it to everyone. Read more

Really a fantastic watch!

The GST B100 is an elegant watch, although on the larger size. Has 300 city world times, alarm (although, this particular watch only has one daily alarm, but not an issue for me) stop watch, timer... and best of all, Tough Solar! G Shocks are really amazing watches... many work on solar, so you never have to worry about replacing the battery or resetting the watch, many have atomic solar for incredible accuracy, this particular watch uses bluetooth to link to your cell phone, and get the exact time off of your phone! Solid, well built, numerous functions... does it sound like I love this watch??? Well... I do! Well worth the price! Casio has hit a home run! Read more

Excellent Piece

TyAugust 15, 2023

I have hairy arms and it catches often under the case, but it is easily resolved with positioning and care. The crown was a bit stiff at the start and I am not the biggest fan of setting the watch via the Casio app. I have to say that I am being a bit critical though. The watch is excellent. I’ve banged the crystal a few times and no scratches. I enjoy the features, the bezel holds up to my everyday, outdoor use and it has excellent movement for the money. This was well worth the purchase. Read more

Awesome watch!

PlaceholderApril 18, 2019

I love the look and features of this watch! I wanted a versatile, durable watch that could handle the daily wear of my job and transition into a casual dress watch. The strap is comfortable and the overall weight is great. I get lots of compliments on it. Paired up with the app on my phone easily, I definitely recommend it to anyone wanting a G-Shock. Read more
