The Gulfman holds a special place for me. It is the watch that brought me into the world of G-Shocks. OK, not all of them. This one:
Which has led to this:
But first, what is the Gulfman? It actually started out as the Fisherman (DW-8600) and has always been in the Master of G line. Signature items being: Titanium backplate and screws, Tide and moon graphs. Pretty simple formula and has held up the "anti-corrosion" banner through that backplate and hardware.
In the "Pre-Atomic" generations we have the grandaddy Fisherman (in blue) and the 1st Gulfman (in yellow and black here).
I learned about these through a couple of great articles by others. In particular Mitch100 did a review that is actually responsible for me going "back" and collecting older versions of my watch. I am very thankful for this.
If you like the color of mine, be forewarned that it is not the original color. ICERC Fisherman were clear jelly. Kung-Fusion helped me figure all this out and while it is a very nice dye job, you should know what you are looking at if you ever think of purchasing.
That Yellow and black one. That is also an ICERC. Mitch100 waxed eloquent on this one as well and I had to give it a try. Topher has this same version, but is beautiful (mine is obviously a wearer).
As we transition in to the Atomic stage of the GW-9100 (the "W" refers to "Waveceptor" which is Casio's term for atomic sync'ing) there was also the Non-atomic version for the rest of the world called the G-9100. Of course all followed up by the GW9110.
For details of the differences between the G and the GW 9100's you can look at the Fraternal Twins.
Both of these are from the Men In Rescue Orange / G-Rescue collection.
Sjors wrote a few articles on a couple varieties of this generation. The non-atomic G-9100, the ICERC edition, and if you don't know, there were a few Gulfman (4? 5?) in the 25th Anniversary. Probably the most loved being the Ocean Grey.
What is funny about this generation is how divided people are over it. Many consider the GW-9100 (the "revolver" due to the 5 circles on the right) the best looking of all Gulfmen. Quite a few others see that very same one as the NON-Gulfman because it does not have Moon or tide. To each their own. All I can say is at least enough people care about these watches to have a strong opinion!
In a thread by GShockMe he points out that the Men in Purple Gulfman is the transition to Riseman (G/W9200) straps and considers it generation "2.5" for good reason.
And that brings back to where we started.
Actually don't find many reviews of this watch. Found one over at MyVerdict which is a decent review.
Another thing you may have noticed is the size has not changed much over the years. This can be tough to tell without a reference, so here is the 9110 next to an "XL" body GA110
Now to be fair on this ledge the 110 is slightly ahead of the 9110. So here is another photo next to the 9100 where they are lined up perfectly.
Still a huge size difference!!! What about the all-familiar 6900?
Again, the 6900 is "in front" so here is another photos lined up:
Yep, it is a little smaller than a 6900! And of course, next to a square.
Actually it is a little bigger than a square. If you don't know, the module of the GW9110 is also in the GW7900. Some people really don't like this. I think it is OK as the 7900 is a much larger watch, and the Gulfman is still built like a Master of G.
Hope this helps, just trying to centralize some good Gulfman info from around the web.
