Product Description

Casio

With the launch of its first watch in November 1974, Casio entered the wristwatch market at a time when the watch industry had just discovered digital technology. As a company with cutting-edge electronic technology developed for pocket calculators, Casio entered this field confident that it could develop timepieces that would lead the market.

Today, Casio is focusing its efforts on solar-powered radio-controlled watches: the built-in solar battery eliminates the nuisance of replacing batteries, atomic timekeeping means the users never have to reset the time. Recently, Casio launched a series of Bluetooth watches that sync to the users cell phone to automatically update the time. Casio is always moving time forward.

    --- Warning: Long, opinionated review ahead ---

    I could go on and on about how many watches I own (40+), I could list off the caliber of watches I have (Jaeger-LeCoultre, two Rolexes, Zeneth, Franck Muller)... but what I do want to go on about is my love of this Giez watch.

    I have many watches (see above) and many of them are the various models of Casios which have been released over the years; from the first pathfinder watch to the current Riseman. The Giez GS1100 is by far one of my favorites. Reason - Form, Function and a wondrous movement.

    Form - Simple and clean at first glance, then as you look closer the detail comes to light.

    Function - it does what it should do. It is one of the most accurate timepieces on the planet. On the most basic of levels, it tells time, has a stop watch, one daily alarm, day and date. For those who need it; it has world time mode and it (the watch) supports the National Institute of Standards and Technology reception standards for the US as well as those for Japan, The UK and Europe.

    Here is a little, how shall we say... commentary:

    The watch is fluid, it has a gear driven movement (the same as the $900 Oceanus line by Casio). It should be looked upon not as a digital watch but as a precision time keeping instrument. The few reviewers whom complained about the movment taking forever; stop playing with your watch, it's not a toy. Set it and know that it works. As an aside, if you are a global jet setter and you need to change the world time city, press the mode button and then immediatly hit the reset/advance button; it will advance the second hand/city indicator with out having to wait for the current setting to queue up.

    Top quality watch! Full feature set with the added bonus of Solar and Atomic clock sync'ing. The build is very good and I really like the well thought out style of the watch. It does so much so well it moved me to write a review - which I very rarely do. It seems to be the perfect Expedition watch - a rugged and accurate instrument.

    Great looking watch, feels and looks solidly made - very "macho" while maintaining a degree of quality and class that is missing in many other very expensive brands.
    With an attractive design, lots of function and clear function layout, it is, for the (Amazon) price, excellent value.
    On the downside, rather too chunky - sits high on the wrist which makes it prone to snagging - and the resin band gets "itchy" if worn tightly enough to eliminate too much slack.
    I find the day function symbols a little too small for my ageing eyes
    The operations guide is confusing at first and procedures for taking advantage of all the functions appear a little complex - it took some time before I could understand the different modes and get comfortable enough to use most of the functions. After 6 weeks I still could not use them all without going back to the manual. The stop-watch function is certainly intuitive, however.
    Synching with the Atomic time server is rather hit or miss - especially, for US buyers, if outside the 600 mile signal radius from Fort Collins, CO - but the accuracy and reliability of the watch appears to make any gap between synchs moot.
    Alarm beep is almost inaudible with no apparent volume control and doesn't work at all when following some function procedures (on my watch) - like setting "Home City" which requires you to "hold down A for about 5 seconds until alarm beeps twice"
    Despite the above, I am becoming much more comfortable with the functions as time goes on and am increasingly pleased with my purchase of this watch.

    Way to go Casio! This is the watch I have been wanting for a long time. Should have bought one sooner. It was easy to set up and now I don't have to worry about batteries and not having the right time and date. Since receiving this watch, I checked the time several times a day against another verified source, to see if the watch was keeping the right time. I now trust the time indicated as true. Was worth every dollar I paid. I highly recommend this watch to anyone needing a "set and forget it" new watch or replacement.

    It works great. The second hand lags if not left face up due to power saving mode, but you get use to it. I have been wearning it for work and play and it looks like it is worth more than paid for.

    I have about 50 watches - from expensive mechanicals to fairly complicated multi-function chronos. This is my 6th Casio, and I have 3 other solar-atomics from them which take abit of reading to learn how each works naturally. But it's NOT "rocket science." Each watch is abit different. My experience is that this watch works fine in all respects, has a nice look, nice functions, "set it and forget it." Easy.

    Possibly a metal and resin band might "jazz it up" abit. But for the price and features, it's not a big deal. Casio really has it over Citizen and Seiko on great looking watches with atomic/solar features, plus all the other usual chronograph and multi-dial features. And all at very reasonable prices. Five stars from me, and I am a tough grader when it comes to watches.
