A friend asked me the other day what I thought of the Gulfmaster Ocean G Shock series of models from Casio, which appear to be the culmination of the “pack it all in” concept with both digital and analog (motorised) display and taken to it’s limits?
If you check out the many videos that are around, this is a watch absolutely stuffed with functions, is the latest thing and I should like it. BUT when considered against the Casio Rangeman for example I’m of the opinion that maybe it’s just too much. With the addition of analog function it’s almost overloaded and more importantly it’s twice the price. Now don’t get me wrong here, I’m all in favour of more functions and I like the Gulfmaster but would I buy it? and the answer I’m afraid, is no I wouldn’t. There is also a point when you start adding analog and digital functionality where you have to be careful of over-complication and despite how clever Casio have been, I’m not sure if they’ve carried it off.
Compass mode – Hands become True North pointer. The digital display indicates angle in degrees between the 12 o’clock and the True North pointer. Declination can be set in menu.
Take the Tissot Solar Expert Pro for example – now that’s a feat of display engineering if ever there was – utterly simplistic analog appearance and yet with enormous ABC functionality. Done with the most clever fusion of touchscreen, digital and analog micro-motor technology, it easily surpasses Casio in the complication v clarity stakes.

The Casio Rangeman on the other hand I like why? Well first off I like owning it. I like it because it manages the same functions (which are ideal for me) as my Protek ABC 270B, but in the G Shock classic tradition. I like it because it’s all digital with no analog provision and looks actually quite plain, or unobtrusive perhaps is a better description. Just another G Shock you may think, but it’s actually very much a wolf in sheep’s clothing. The function (QW3410) set is actually very similar to the Gulfmaster, but with the omission of any analog clutter, is without Tidal information, but has the added bonus of a Sunrise/sunset function and a snooze Alarm (don’t know why that got missed on the Gulf). The Rangeman is also in practice, smaller on the wrist, which is an important consideration when dealing with these multi-function models.
Both models use the “Smart Access crown, rather than separate pushers as my Casio Pro Trek PRG270B-3, which is an improvement and as I say feature wise are very similar. And with such large functionality it is pretty obvious all these models are going to be big (though that said, the advance in miniature technology is nothing short of amazing) – indeed they are all similar, but shape and band/case fit tends to dictate which wears smaller on the wrist and the Rangeman, surprisingly for a multi-function G Shock, though large is neater than expected.
None of the models are heavy though with the use of resin case technology. One of my dreams however would be if Casio could reduce the sizes of these watches to around 45 mm x 45 mm and under 15 mm case depth, but I’m very doubtful that will ever happen as there is this compulsion to pack more in with every model . . . .
However function wise the Rangeman is very comprehensive and with basically 3 versions – the GW-9400CMJ-3ER shown here with Green case and Positive display – the GW-9400-1ER with Black case and Positive display and the GW-9400-3ER with Green case and Negative display. I should say that my personal view is most Casio Negative displays are not in the same league as Positive ones.
The technical data for this Limited model is as follows –

Not many downsides for this model, though I would liked to have seen a sort of 2nd Time Zone/Home Time SWAP feature, but I’m nit picking – changing to another World Time is easy enough so hardly an issue.
So in answer to my friend’s question – Yes I like the Gulfmaster but it’s not perhaps as tough as it could be with that unprotected glass, the analog hands feature whilst very good I don’t really need, the prominent text bezel seems over-large for purpose, Tidal and Moon stuff I don’t need and I just prefer the rugged tough look of the Rangeman, which is as well specified anyway. Now that said, there is no doubt it is a superb watch and might well suit everyone so much that I’m the odd guy out, but it’s a personal thing and remember this was a question posed to me just the other day. I have NOT seen the Gulfmaster in the flesh, so it’s a sort of remote opinion (which I never like doing) and who knows if I had it in my hand or on my wrist, my opinion might change and I might love it, though as I say fortunately I haven’t seen one close up – 😉
The Casio Rangeman GW-9400CMJ-3ER shown in conclusion is what I call a set and forget watch, looks like any other G Shock, which it isn’t and is probably the toughest watch produced, so I’ll stick with it until I see better. Which could be a considerably long time . . . . What can I say . . . .
Note – this post not intended as a comparison between the two models shown, rather I was asked for my personal opinion which I gave “in Post” as it were. . . and as I was about to Post on the Rangeman, it seemed the ideal opportunity.
