It was over 30 years ago, a CASIO engineer won the battle against the laws of nature. He designed a watch that would resist centrifugal and impact forces, as well as high water pressure. Since then, the name G-SHOCK has become a byword for independence and pushing the limits. G-SHOCK watches are the most durable digital and analog-digital watches in the industry, trusted by military personnel, law enforcement, surfers and outdoor enthusiasts around the world. Along with this, G-SHOCK is highly touted in the fashion world, worn by icons in hip-hop, sports, and design. With limited edition collaborations being released often, you can always find a G-SHOCK that matches your personality and style. ## Features - Solar-powered sport watch featuring atomic time keeping, world time in 48 cities, and EL backlight - Features 1/100-second stopwatch, daily alarm with snooze, 12- and 24-hour formats, tide/moon graph, 31 time zones, and day/date/month calendars - 50 mm resin case with mineral dial window - Japanese quartz movement with digital display - Resin band with buckle closure - Water resistant to 200 m (660 ft): In general, suitable for professional marine activity and serious surface water sports, but not scuba diving. ## Technical Specifications | Specification | Value | |---------------|-------| | Age Range Description | NO | | Asin | B00309HQPK | | Band Colour | Black | | Band Length | 9.5 Inches | | Band Material Type | Resin | | Band Width | 1.2 | | Bands | 1 | | Best Sellers Rank | 1,046,007 in Fashion (See Top 100 in Fashion) 7,494 in Men's Wrist Watches | | Brand Name | G-Shock | | Case Diameter | 50.0 | | Case Material Type | Resin | | Case Thickness | 15.5 | | Character | Fashion | | Clasp Type | Sliding Clasp | | Closure Type | Buckle | | Crystal | Mineral | | Customer Reviews | 4.5 4.5 out of 5 stars (2,298) 4.5 out of 5 stars | | Dial Color | Black | | Display | Digital | | Embellishment Feature | Crystal | | Face Style | Crosshair | | Global Trade Identification Number | 00079767435196 | | Included Components | Casio G-Shock MB-6 GW7900B-1 Atomic Solar Rescue Multi-Band | | Item Shape | Round | | Item Type Name | Casio G-Shock MB-6 GW7900B-1 Atomic Solar Rescue Multi-Band | | Item Weight | 71 Grams | | Manufacturer | G-Shock | | Manufacturer Part Number | GW-7900B-1CR | | Model Name | 'Atomic Solar Rescue Multi-Band' | | Model Number | GW7900B-1 | | Model Series | G-Shock | | Number Of Items | 1 | | Number Of Packs | 1 | | Pattern | Solid | | Power Source | Solar Powered | | Series Number | 1 | | Special Features | Atomic Timekeeping, Solar Powered, Water Resistant | | Sport Type | marine activity, water sports | | Strap Type | Single Piece Strap with Buckle | | Style Name | Solar Atomic Rescue GW7900B | | Theme | Watch | | Upc | 076797435196 033586475146 079767435196 961613302496 | | Warranty Type | Seller | | Watch Movement Type | Japanese Quartz | | Water Resistance Depth | 660 Feet | | Water Resistance Level | Waterproof | ## Images ![Casio Men's GW7900B Classic Solar Atomic G-Shock Watch - Image 1](https://m.media-amazon.com/images/I/612nyor1ebS.jpg) ## Available Options This product comes in different **Colour Name** options. ## Questions & Answers **Q: Does this watch receive a time signal in Asia and Europe** A: I had one in Afghanistan that did not.

As is the size. A 50mm width, and 15mm height ensures it will be noticed. However, the display is a double edged sword. The negative display keeps within the stealth mode, BUT it is impossible to read in low light conditions without the aid of the EL light. By low light, I mean indoors under domestic conditions (not bright office light), or outdoor in winter. Sunshine really pops the display into life. The functionality is superb, the atomic function ensures 'to the second' accuracy, and being solar means the watch will remain intact without costly battery replacements, and new gaskets to retain it's waterproof qualities. The resin strap is of good quality, and is supremely comfortable due in part to the 'wings' at either side of the lugs which hug your wrist.I have had mine for some months now, and have 'modded' it slightly by replacing the chrome buckle with a black one, removing the white writing around the bezel, and replacing the silver bezel rivets with black ones, and painting the 'G' on the light button black, all just to highlight the stealthiness of the design.I do love it, and it is almost a great watch, apart from the fact that you can't tell the time in poor light!! ### ⭐⭐⭐⭐ Display is hard to read *by on Reviewed in the United Kingdom 15 October 2022* I’ve had this for the past few years and it’s great watch in every way except two things are a pain.The negative display looks cool but it’s really hard to read most of the time and you spend more time moving your wrist to catch the right angle to read it, or have to illuminate it.The solar power indicator and hourly time signal are tooooo small to see half the time.Would I recommend buying one? No, get the normal version. ## Frequently Bought Together - G-Shock Solar Atomic Rescue GW7900B Black/Black One Size - Casio G-Shock GWM5610-1 Men's Solar Black Resin Sport Watch - ECEEN Solar Watch Charger, 8 Hours Timing Off with Men, Women & Square 3 Caps, LED UV Light Charge Eco Driver Watches Compatible Casio/Tough/Protrek/Seiko/Citizen/Garmin/Timex/Bering/FANMIS (Black) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.pa/products/49615641-casio-mens-gw7900b-classic-solar-atomic-g-shock-watch](https://www.desertcart.com.pa/products/49615641-casio-mens-gw7900b-classic-solar-atomic-g-shock-watch) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-09-12*
