Life-long G-shock owner. I'm not impressed. I prefer BIGGER size.
- There's absolutely nothing wrong with the watch. I'm a life-long G-shock owner of 20+ years and have loved them for their BIG size. I was a bit dumb in that I ordered this thinking it was as large as the last one I had, but it's not. As a man, this watch is not the largest/clunkiest G-shock you can find. Keep searching around. - Backlight is dim and green. The last G-shock I had it was super bright white. If I had been able to examine this watch in real life in a store, I wouldn't have bought it. I would have searched for a bigger G-shock. I also saw in one of the reviews some guy talking about how this watch's red color really stands out, as opposed to an orange model he owned. I'd have to disagree. The red does not really jump out at you. It's just a standard medium-sized red G-shock. Nothing more.

思った通りの赤色で、今まで着けてたモデルよりもバンドの腕に当たる部分が劣化しても切れそうもないので安心しました。 前回の物も海外モデルで電池が交換出来なかったのですが、バンドも壊れたし、ライト点けると時間が消えてたので寿命だ買い替えましたが、前回のも五年使えたので今回も海外モデルにしました。 時間も日付も合わせて送ってくださるので、手間が省けて有りがたいです。

This is a truly gorgeous watch in the G-Shock line. As a guy that lives in a beach town, its "G-LIDE" functions were exactly what I was going for. And, as a former lifeguard (way, way back in college!), the "Red Rescue" variant was one that I definitely wanted to have. As a G-Shock, it sits at the upper-end of sizing but still less than some of the larger watches out there. So, how will it sit on your wrist? If you have a wrist sized at 7.25" like mine, then the pics I've attached to my review will be exactly what you can expect. I find that it's truly a comfortable watch to wear and has some great features to it. Overall, it's definitely a win! I've put in why with my categories below. Comfort = 5/5 Yep, it's truly a comfortable watch to wear. With my wrist sized right at 7.25", it fits nicely in the 5th notch from the top of the watch (see the pic above). The flaps sitting just under the dial makes for an excellent fit on your wrist, too. That is a HUGE win when you're in the water. It just fits really well. Comparing it to my DW9052-2 (also reviewed on Amazon), I'd say that this is equal to comfort. I can (and have) slept with this watch on overnight and never had it feel uncomfortable at any time. The watch gives enough heft to let you know that you're wearing a watch BUT it never feels heavy. Appearance / Aesthetics = 5/5 And, the watch just looks COOL! Yes, it really does! When you match it up with its "Rescue" features, you feel that it has the DNA of a lifeguard. The red primary color with the black buttons makes it an attractive watch that never feels overdone. The white lettering is a nice touch, too. Casio could've just made the letters black but the tri-color design truly works. Functionality = 5/5 Considering its "G-LIDE" functions and G-Shock's usual countdown timer, 2 stopwatches, alarm, and World Time features, this is truly a winner. I found the setting of the watch to be easy, even plugging in the Tide and Lunar cycle information. The instructions show you how to plug in values with tables at the end of the booklet. However, to be truly accurate on your Tide and Lunar Cycle (e.g., Lunitide) information, I recommend consulting a dedicated resource on the Internet. I used a combination of info on 2 websites (tideschart.com, surf-forecast.com), a Lunitidal Interval calculator (lunitidal-interval.com), and an iPhone app that I bought to bring the most accurate info together on the watch. It asks for your Longitudinal and Interval info when you set up the watch. And, it's easy enough to change when you visit different coasts. The backlighting works very well and all of the buttons are easy to push and responsive. Transaction Experience = 5/5 Amazon's Seller, "The Watch Locker", came through quite well with this purchase. They walked away with a 5-star rating from me for their delivery of the watch (right on their promised timeline), the condition that the watch arrived in (new in the box with all of the original packaging), and the watch is an authentic G-Shock (verified personally). The price of the watch was definitely competitive and worth every penny. Overall, this watch is an excellent addition to the G-Shock line and I am personally very pleased to have it in my collection. I also have the black version of the "Rescue" line which also comes away with an identical assessment to the red. However, if I had to choose between the two of them, the red one comes away as my favorite because, IMO, it truly comes away with the feeling that it's a "Sea Worthy" rescue watch. TIDAL ACCURACY UPDATE After wearing this and my black Rescue watch for several days, I found the tidal indicator to be inaccurate with my locally-verified Lunitidal values. However, I found the "secret" to getting the tidal bar to be completely accurate. After calculating your Lunitidal Interval, add 7 hours to your value in the watch and your tidal graph should now be accurate. My watch has been completely accurate for the last 2 days. So, an example is where your Interval is set to 2:26, you would add 7 hours to that for a new value of 9:26. I hope this helps any of you that noticed the same inaccurate tidal graph reading.

Pros: - Nice rescue red color with black buttons. Great color combination in my opinion and works well with most outfits. - Fit for all kinds of rough activities. You can drive this thing over with a car and it will still be perfectly intact (seriously, look it up on youtube) - Feels really good on the wrist and easy to adjust - Lightweight - 200 meter/20 bar water resistant. You can swim with this watch without worrying. Be careful about showering and using shampoo and other chemicals though, as it could potentially tarnish the color (it hasn't happened to me, but it's worth to have in mind if you want to keep the watch fresh). Cons: - The world time for Tokyo and Hong Kong, for example, are showing the time wrong by one hour (regardless if i change DST on or off). Maybe there's a way to change that. Not a big deal though, because everything else seems to be right. - I thought the feel of the watch would be more rubber-ish, but it's actually more of a plastic feel. Still feels great to wear though!

100% original. As fases da lua são bem precisas, tem me ajudado muito na pesca esportiva. É só ajustar a sua localização (long e latit) que acerta em cheio. No meu caso depois que configurei a localização as fases da lua foram automática. Podem comprar sem medo!!

No complaints. Wear as my everyday watch! It’s solid!
