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

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: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. 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.
