Had Absolutely No Dislikes was worried at first when I read it was sold by Fashion House Discount and Not Amazon exclusively. I put it to the Fake VS Real test and it passed 100% this is an AUTHENTIC Casio Timepiece all packaging was Authentic 100%. I've been a Casio fan since the old Calculator watches and I've always wanted a G-Shock but it had to be the RIGHT one. My last Casio was a Tough Solar that I purchased 5 years ago or so. It still works and within the +/-15 second range (7 seconds behind my Samsung Smartphone) The included directions are fine but as I'm over 40 had to download the PDF for a larger picture. Set watch up to my specs within 5 minutes and calibrated against my smartphone as I always do. Beautiful Timepiece I hope the gold doesn't wear off but I've read in other reviews from some two year plus owners that theirs still look fine. Very Satisfied Customer! ... show more

The media could not be loaded. It’s a very nice looking watch, easy to set and very comfortable. I definitely recommend this watch. The price is very good also.

    • Better in Person!
This watch looks really great in real life. Better than the pictures. I got it for my Son who's in middle school, and told him I thought it was too fancy. He kept it anyway, wears it every day, loves it, and it survives everything. Quality, toughness, reliability you'd expect from G-Shock. It's the only watch brand I wear. This one is a winner. ... show more

    • A good watch if on sale
It's a good watch for the price, though the plastic feels a bit cheap.

    • Vendedor Marca y calidad
Casio ha sido una marca confiable que he usado desde la juventud, he devuelto este G Shock por dos cosas, 1) no tomé en cuenta el tamaño del mismo y fue demasiado grande en mi mano, creo que fallé en ese aspecto y pues esto puede servir para alguien más a la hora de comprar para que tome en cuenta el tamaño 2) la luz se prendía constantemente varias veces durante el día, no se si fue algo que active a la hora de programarlo o era un fallo de fábrica pero que en realidad no lo hallé normal que eso pasara, pues durante el día no necesito luz para leer un reloj, para la noche estaba bien pero no para el día, bien ahora hablaré de la marca y la calidad de reloj, en general Casio es una buena marca, el reloj se ve fantástico, buena construcción, el color dorado era fantástico me encantó pero esos dos motivos fueron la razón para devolverlo y siempre confiaré en Casio, el vendedor le doy pulgar arriba pues hizo bien su trabajo con mi compra y cumplieron con su trabajo el proceso de compra, venía bien empaquetado y bien cuidado, el envío todo estuvo excelente, falta ver cómo se comportan con mi devolución ya que aún no lo han recibido pero creo que no habrá problemas con ello pues veo que dan un buen servicio al cliente, creo que no tendré nada malo que opinar de ello, he dado 5 estrellas pues no tengo nada negativo que decir con respecto a esta compra y el artículo. El vendedor es bueno si algún día se encuentra por comprar algún artículo de My Gift Stop no lo dude su compra será segura, bien atendido y seguro que tendrá su artículo ... show more

    • Impressed, and elegant looking G-Shock.
Like many reviews I am impressed that this timepiece looks much better than in the photo shown. Elegant is the right word which I would not normally apply to a G-Shock (and I have had several). I purchased this for work but would feel very comfortable wearing it in a more formal environment. The black LCD with white lettering are very easy to read. This says a lot since I almost always get black watch faces with white hands so that I can read them without my glasses. My only issue, as with all Casio brand watches is that the instructions are not easy . . . but with a little persistence and re-reading you will figure it out. ... show more
