## Description

Durable G-Shock watch with shock resistance, world time, solar power, and 20 bar water resistance. Designed for high functionality and comfort in harsh conditions.

Review: Great fitting, large G-Shock with a soft matte resin strap. - This is by far one of the nicest G-Shocks that I have come across. The face is chunky, depth wise, and so might not get along with a tight fitting cuff. But because this is a solar charged watch I tend to let it sit outside the cuff and Its usually worn in casual clothing anyway. I find this watch to be very cool looking and stylish, even though is designed to target the Rescue service market. It doesn't look out of place in any situation other than when wearing a suit. It's also worth noting that I have a very small wrist and I found the new mudman too big for me and it just didn't 'hug' my wrist like this model does. And because the strap is soft and matte it makes it even better and there isn't lots of excess strap sticking out which I find with most G-Shock. It's also I very light! I kinda wanted a bit of weight to this but it's so light. You can be guaranteed of very accurate timekeeping too due to this watche being atomic, meaning that it updates the time every day making it accurate right down to the seconds. Of several negative displays I have come across in the G-Shock range this one is the easiest to read but I do find myself using the light often enough. In terms of functions this watch has all you need and more for the average guy and it all works very well. My only complaint is that this watch has frozen on me twice and I've only had it a month. If this happens to you, you can press three buttons at once to reset it. I think it's the two buttons on the left and one of the buttons on the right. This works for a lot of G-Shocks if they freeze or act up on you. Overall this is a nice fitting stylish and functional rugged watch and I'd recommend it to people in the services (if the thickness of the watch won't be an issue) and to G-Shock fans/collectors who like a stylish G! (Eminem wears this G! Which will help sales!) I'm not a very good reviewer but I hope this helps answer some questions buyers may have.
Review: Well-balanced, one of the best G-Shocks out there - This G-Shock hits the sweet spot between price, quality & features. It includes tide & moon phase info, several alarms (incl. snooze alarm), stopwatch & timer, world time & multi-band 6 (radio synchronisation with atomic clocks), an inverted digital display that looks fantastic (though it does sacrifice visibility for looks, so if you want visibility get the standard black-text-on-white-background version) and solar-powered battery. It’s not the largest G-Shock and definitely not a Master of G or one of the more luxury-oriented ones, but if you’re looking for a tough, great looking & reliable watch to use as your daily workhorse, during tough jobs or trips and not worry about damaging it (did I also say it looks great?), and you want or need a couple of neat features like tide & moon phase, you cannot go wrong with this choice. The auto-illumination feature (the face lights up when you move your wrist to look at it) is also practical and mitigates the reduced visibility of the inverted display that wouldn’t be legible without it at night or in a dark location otherwise. A steal for the price & features, and in my opinion a well-balanced piece that gets the best Casio G-Shocks have to offer.

## Questions & Answers

**Q: does this item have a positive display**
A: If you mean is the display easy to read? The back ground is black and the digits are grey. It is not the easiest of watch's to see in daylight how ever I got it because it illuminates and I use it a night. It is solar charged, doesn't require battery's . It is 100. % acurate  as it picks up radio signal and resets itself in early hours of the morning. It's a good watch.

**Q: Is this original item, how many functions it has?**
A: Yes original. All the usual digital watch functions such as stop watch. world time etc. Shows moon phases and tide information. The watch is solar powered and radio controlled by the atomic clock

**Q: How do i set the hourly beep on g-shock 7900b 1er**
A: Scroll through the alarm settings. It's one of them. 6 taps in the alarm mode(SIG) 👍🏻

**Q: How much power when it arrives? Does the seller maintain safe-power levels?**
A: Casio watches come in an opaque tin. Without light they enter a power saving mode to preserve charge. Once they are exposed to light again they function normally but you need to maintain the charge. I leave mine by a window when not in use. Depending on when it left the factory the watch should have at least a medium power level. I'm sure that retailers don't open the tins to charge them though, so it's possible the watch would need charging, but not probable.

### ⭐⭐⭐⭐⭐ Amazing work watch but style comes with a big price premium.
*by I***H on 22 March 2014*

There are so many reviews online of this watch that the spec hardly bears repeating but what do I think? Classic G-Shock case design though slightly oversized to make it appear bulletproof. Makes it hard to slide slim or tailored cuffs over it due to the increased height. Despite the size it doesn't actually look too big on the wrist and is very comfortable due to the additional 'wings' covering where the strap meets the case. Multiband 6, Tough Solar and the usual G-Shock features mean it is a watch that is truly accurate and should need virtually no maintenance. Looks fabulous in the black with the negative LCD. After reading the reviews I was actually surprised how easy it was to read. I can see it isn't for everyone but combined with the automatic backlight I have never had a single issue reading the display. Due to the darker display it is perhaps slightly more affected by reflections but with the right light the digits really stand out just like the photos. The only disadvantage worth noting is that you pay a big price premium over the standard watch to have the black version. It was a style choice for me in the end and I am glad I made it but it is hard to justify the extra money for any other reason. I assume it is so much more because this model isn't a UK official watch (it doesn't appear in the Casio UK website) but rather one destined for other markets.
