Product Description

This Casio men's G-Shock watch is perfect for seafarers; it provides moon data and a tide graph so you'll always know what the tide is. In addition, the digital watch also shows the time in 29 time zones, has three multi-function alarms, a countdown timer, a stopwatch, and auto electroluminescent backlight with Afterglow. The stainless steel case has a black resin bezel that provides shock resistance. A matching black resin band provides a secure fit and the watch is water resistant to 660 feet (200 meters).

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.

    The G-Shock Gulfman is a great watch.

    Well, there is specific data you need to enter to show the correct tides, moon phase, etc.

    I found the tide setup fairly easy with help from the internet.

    PROS:
    1) comfortable watch to wear: as other reviewers point out, it feels well balanced despite it's physical size.

    2) Fits well, even for smaller wrist sizes: the material, shape of the band and its width all work to make this a comfortable watch.

    3) Titanium backing (lightweight and resists corrosion).

    4) The tide and moon functions seem to be fairly accurate and are fun/useful to have readily available.

    5) Really, it's not that bulky when compared to many other watches. For example it's comparable to a self winding analog watch.

    CONS:
    1) It's bulk is felt if you wear it with tight fitting sleaves (such as knitted wrists on a jacket).

    2) The booklet that comes with it is a little tedius to use (small pages and print), which may be why some people found it difficult to set up. However, you can easily find a .pdf file on the Internet that is full size and easier to read.

    In general, the Moon Phase and Tide functions require you to invest a little more time in learning to use the watch - but that ought to be expected. In the end, you may even enjoy learning some of the science behind it.

    When I received my Gulfman, I immediately went to a tide chart and set up the watch for the tides. Worked well! The only problem was that the chart was so tiny that these older eyes couldn't read it without some help. Probably better for the younger set.
    The NEW model of the Gulfman...atomic and such, do NOT do the tides and moon. What a pity....that makes THIS model more useful (and cheaper) than the new one.
    I like the looks of this one...my first G-Shock. However, now having had this one (and given it away to a friend, who loves it...HIS first G-shock) I'm convinced that you should save your money and get the RISEMAN which tells temperature, barometer, altitude...all in a nice package.
    BUT....the Gulfman I consider a BEST BUY! Best bangs for the buck...should be able to get this for about $60.

    I bought the Gulfman for the 'Tide and Moon Phase' features. On the downside, the graph is tiny. In natural lighting however, it is easy to read. I don't have any problems since I mostly view the 'tide and moon phase' graph outdoors.

    This G-Shock has a list of gadgets that would make even MacGyver happy! I must admit, I'll hardly ever use most of them.

    The coolest feature of this Casio G-Shock Gulfman is the 'Auto Light Switch'. When this feature is turned on, the entire watch face illuminates automatically when you angle the watch towards your face. You can even adjust how long you want the light to stay on! This feature can be easily activated (and deactivated) by simply pressing the top right switch!

    Finally! A watch that can display the time without the user fumbling to press a switch in the dark!

    Another great feature of this G-Shock Gulfman is the lightweight, rust resistant, titanium casing. This watch is built tough just like the earlier G-Shock models. Being lighter, it is more comfortable than the older G-Shocks with heavier stainless steel casings.

    In addition to surf fishing, I wear the Casio G-Shock Gulfman while operating power tools. As expected for the G-Shock series, the watch's black resin bezel has so far handled the vibration of standard power drills and, even a 20-Inch Chain Saw!

    I am a G-Shock fan, and I really find myself wanting to LOVE this watch. I think it sells itself on a "concept" more than any actual, useful features - but that's fine as long as you're aware of what you're buying.

    Typical of all G-Shocks, it is incredibly durable and feels rock solid. The buttons on this Gulfman are actually larger and more easy to press than many other G-Shocks, and that's a big plus. Let me try to break it down:

    Pros:
    - Sharp-looking display, slightly cluttered, but looks impressive.
    - Titanium backplate and screws (essentially makes this watch rust-proof).
    - Moon and Tide displays actually work with reasonable accuracy - after you have spent an hour on the 'net working out how to set them for your location :)
    - Backlight ("dual illuminator") looks fantastic (after you see it yourself, you will understand).

    Cons:
    - Moon phase display is TOO SMALL. I can see it, but, it needs to be slightly larger.
    - No dedicated Light button at the bottom of the face. Most G-Shocks have this button. It is sorely missed on this watch (instead you use the top-right button for the light)

    This watch also shows a cool little animation as you switch between the various modes; for those interested, the modes are: TIME -> TIDE/MOON -> WORLD TIME -> STOPWATCH -> COUNTDOWN TIMER -> ALARMS. You have 2 alarms plus a third snooze alarm. As with many G-Shocks, you can set the display to flash with the alarm/hourly chime/countdown timer - completely pointless but incredibly cool at the same time :)

    The tide graph has been working well for me, after I finally managed to set the correct values within the watch. No big deal if you are prepared to spend a bit of time searching on the internet.
