Casio Men’s G9100-1 G-shock Gulfman Tide

Casio Mens G9100 1 G Shock Gulfman Tide @

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

The Casio StoryWith the launch of it is firstborn watch in November 1974, Casio entered the wristwatch market at a time when the watch industry had just encountered digital technology. As a company with cutting-edge electronic engineering devised for pocket calculators, Casio entered this field convinced that it could fabricate timepieces that would lead the market.

In constructing it is own wristwatches Casio begun with the basic question, “”What is a wristwatch?”" Rather than plainly making a digital version of the conventional mechanical watch, we thought that the idealisti wristwatch ought to be something that shows all facets of time in a consistent way. Based on this, Casio was competent to construct a watch that displayed the precise time including the second, minute, hour, day, and month — not to mention a.m. or p.m., and the day of the week. It was the initial watch in the world with a digital automatic calendar function that annihilated the need to reset the calendar due the variation in month length. Rather than using a established watch face and hands, a digital liquid crystal display was adopted to better show all the information. This culminated in the 1974 launch of the CASIOTRON, the world’s original digital watch with automatic calendar. The CASIOTRON won acclaim as a groundbreaking product that represented a finish departure from the conventional wristwatch.

Casio transformed the conception of the watch — from a mere timepiece to an info device for the wrist — and undertook product planning based on this innovative idea. We invented not only time functions such as global time zone watches, but also other radical new functions using Casio’s own digital technology, including calculator and dictionary functions, as well as a phonebook feature based on memory technology, and even a thermometer function using a built-in sensor. The memory-function watches became our DATA BANK product series, while the sensor watches devised into two distinguishable Casio product lines of today: the Pathfinder series displaying altitude, atmospheric pressure, and compass readings.

In 1983, Casio launched the shock-resistant G-SHOCK watch. This product shattered the notion that a watch is a fragile piece of jewelry that needs to be handled with care, and was the result of Casio engineers taking on the challenge of creating the world’s toughest watch. Using a triple-protection design for the parts, module, and case, the G-SHOCK offered a radical new type of watch that was unaffected by strong impacts or shaking. Its practicality was without delay recognized, and it is distinctive look, which embodied it is functionality, became wildly popular, resulting in explosive sales in the early 1990s. The G-SHOCK soon adopted respective new sensors, solar-powered radio-controlled engineering (described below), and new materials for even better durability. By always employing the latest technology, and continuing to transcend traditionalisti thinking regarding the watch, the G-SHOCK brand has become Casio’s flagship timepiece product.

Today, Casio is focusing it is attempts on solar-powered radio-controlled watches: the built-in solar battery does away with the aggravation of replacing batteries, and the radio-controlled function means users never have to reset the time. In particular, the radio-controlled function represents a revolution in time-keeping engineering similar to the affect produced when mechanical watches gave way to quartz technology. Through the further development of high radio-wave sensitivity, miniaturization, and bettered energy efficiency, Casio proceeds to develop a whole range of radio-controlled models.

4Despite its size, it’s a comfortable and useful watch
By Honest Opinion
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.

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.

4A good choice
By G. Webster
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:

– 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).

– 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. However, the graph is limited by it’s own “resolution”; by that I mean the way the bar-graph is set up with only 6 segments, it will only flick to the next segment every 2 hours, so you are never really going to be sure exactly when high tide is for a particular day (as well as showing the current tide in timekeeping mode, this watch allows you to easily step through the hours of the day and see where the tide will be at that time). Similarly, it allows you to easily step through the days of the month and see what the moon will look like on that date. Anybody who depends on the tides/moon with any regularity will already have charts that show this information more clearly – but it fits well with the theme of this watch and it is a welcome feature.

… Is titanium really necessary on a G-Shock? Probably not, but as I said at the start, this watch is selling the “idea” that it was made for the ocean and anybody who interacts with the ocean. And in many respects it fits very well.

In summary, if you are the type of person who is interested in tides/moon, and who spends time near the ocean, this may well be a very enjoyable watch for you to own. It has great “wrist presence” with it’s chunky plastic bezel, it weighs practically nothing thanks to the lack of steel, and it feels kind of cool just jumping into the ocean with a titanium-backed monster called a “Gulfman” strapped onto your wrist :)

On the other hand, if you are just looking for a general-wear G-Shock, you may want to check out other models such as the Mudman range (Casio Men’s G-Shock Mudman Solar Atomic Watch #GW9000A-1), or my favourite, the DW-5600e (Casio Men’s G-Shock Classic Digital Watch #DW5600E-1V).

5Old Gulfman better than new?
By Mitchell Billings
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.
