model PRW-6600Y-1A9CR empecemos por lo malo rapido: la luz solo dura 3seg maximo, no hay manera de extender la duracion solo 1 o 3 segundos. al activar una funcion como el compass en la noche, el reloj tiene 24hrs pudieron program que la luz del display se quede encendida por minimo 3minutos para que encuentres tu camino puedas reflexionar la mejor ruta, 3segundos me parece una burla para este tipo de reloj de supervivencia, ojala que casio reflexione en lo que vende y mejor la duracion de la luz el reloj se llama "PRO TREK", esta en el nombre. ahora lo Bueno o Excelente. no pense que fuera a ser tan elegante, a mi no me importa yo lo usaria con traje, esta hermoso. el peso es minimo, es delgado para tener tanta tecnologia. el diseño de los numeros esta excelente el extensible apenas y suda un poco la muneca, con otros relojes suda mas pero no se que tipo de extensible sea y esta super fresco. Iluminacion: neta 3segundos, checa el video. peor no se activa al cambiar funciones. no se que estaba pensando casio, pero alguien tiene que ser despedido. la hora se ve con poca luz muy claramente, solo en plena oscuridad encenderias la luz del display. el Lume o el neobrite, dura toda la noche si lo cargas 15min, checa los videos, se ve genial. este reloj esta genial de dia, de noche no seria mi opcion para guiarme, la poca duracion de la luz no ayuda a nada, solo si estas en casa a salvo, usaria otro reloj para senderismo nocturno. aun asi 5 estrellas el reloj esta genial, se ve genial, la hora se ve claramente todo el dia, genial para mostrar en las parrilladas, pero no salgas a caminar con el te vas a perder.

If you are a G-Shock fan and haven't tried Pro Trek yet - you owe it to yourself to try this watch. It's as fully-featured as a G-Shock, but looks less industrial and more "grown up". All Pro Treks are ABC watches (altimeter, barometer, compass) and this one has a Thermometer too. Throw in 5 alarms, timer, stopwatch, world time , and 100m water resistance and you have a do-it-all tool. My favorite aspect of this watch is the stealth look - the band, dial, and case are shades of black and gray, while the hands are bright white. The hands are easy to read, the dial a little less so. The underside of the band is glow-in-the-dark which creates a cool effect at night. The only negative? - this model doesn't have Multiband6 automatic time adjustment. This isn't a deal breaker, but there are some Pro Trek models which have that feature if you want it. Overall, this is a great watch and highly recommended. Read more

This watch is awesome! Been on the GShock train for a few years now and I had been looking at Protreks recently. My main concern being the size. While it is much larger than most of my GShocks, I think it wears very well, even on my thin little bird wrist. The features are great and the colors look even better in person. Glad I went with the more muted colors of the 6611 instead of the 6600. And tough solar is ALWAYS a plus. Being 48% off during Prime Days certainly helped. Only negative is that it is much bigger than my other Casios, so my wife knew immediately that I had purchased another watch. Read more

I've been wearing Casio watches for over 50 years and I must say this is one if yhe best looking watches they have ever made. It has many of the features the G-Shocks have withouth the super thick case. I am thin so some watches are just too large but the 6600 fits perfectly. If you look at the measurements be away they are adding the crown and buttons into the figure. I had also ordered screen savers to protect the mineral glass from getting scratched. I recommend it. PROS: Beautiful and masculine. VERY easy to read even at an angle. Nice size for this yype of watch. Many features but even though I won't be using some of them I need a compass. Atomic clock is a HUGE plus for us time police. 😃 Solar powered so battery should last 20 years. World time and it's very easy to set. 5571 internal movement is easy to use. Very nice silicone band with quick release. Plenty of band holes for thinner wrists. Black buckle looks good. Ither bands will fit.if needed. Easy to use backlight. Glow in yhe dark work fairly well. LOUD alarm. Negative display screen is easy to read. Tells temperature but it must be off your wrist for at least 29 minutes. (This is normal) Altimeter must be set to be accurate and then it works well. Tutorial videos available online. Packed in a wooden box so it looks nice as a gift. CONS: Pricey compared to some other great Casio watches. Band does not have a locking or wratched keeper. Light could be brighter. FYI: Although not a thick watch it may be too thick for formal wear. Makes people want to be like you. 😬 This is a fantastic watch. As I get older and my vision dims it's good to have an easy-to-read-at-a-glance watch. If you are looking for a G-Steel or G-Shock but watch something a bit classier this may be what you're looking for. Highly recommended Read more

Me gustó mucho este Protrek. No he logrado sincronizar la hora con el multiband 6, soy del Edo Mex, tuve que ajustarla de manera manual. Tiene las funciones: barómetro, brújula, altímetro y temperatura. Y las clásicas de un reloj Casio digital. La correa se ve de calidad y duradera. El reloj es liviano y cómodo de usar. Read more
