CasioG-Shock GWM5610-1 Men's Solar Black Resin Sport Watch

And so, the clock is received.Upon receipt, tests and battery:Considering that as I thought that the watch was driving for five days at an ambient temperature of -20, as soon as I got it, I ran the watch through tests of the screen, tilt, auto-backlight, solar panel - everything is normal. Yes, and they did not drive at a temperature of -20, I have already clocked myself, a maximum of three hours at -5, and that is unlikely.On receipt, the battery charge was at "H". During testing, the level almost immediately fell to "M". The next day, a couple of hours on the windowsill and again "H". Now I look at them again "M" - but this is understandable, not the season, however, there is not enough sun and clothes with long sleeves. Yes, and I use it to the maximum - auto-backlight, attempts at manual synchronization, alarms, auto-synchronization ... I'll try to leave it on the windowsill for the whole weekend - maybe it will stop throwing them from "H" to "M" and vice versa.By synchronization:Synchronized without any problems via smartphone. The application is called "DCF77 Emulator".Compulsory synchronization or auto-night synchronization with towers has not been successful yet. Finding out how much they are in a hurry or lagging behind in a month - I have not yet dealt with it, too little time has passed after receiving it.By subject:The clock arrived made in Taiwan. I do not know why, but subjectively pleased more than Made in China. There are no scratches, dents, abrasions on the glass, everything is perfect. The mechanism itself stands in the case evenly, without distortions. The back cover has no scratches or abrasions, the bumper to the body in the area of ​​the buttons (and, in principle, around the perimeter in general) adjoins very tightly, there are no gaps from the word absolutely. The end of the strap at the end (where the rounding is) without roughness and burrs - judging by the shiny small thin strip, it was processed with a laser or something hot, yes, I am a "little" perfectionist. The viewing angles are excellent, so that you can somehow look at the watch - so that at first glance the information on the dial is not clear - you need to seriously twist your hand ... I do not feel absolutely problems with the date "month / day or day / month" I am quite comfortable with the existing format - if I could switch the format, I would switch to the existing one.I did not carry out tests with a piece of ice on the dial - then there is no ice, then I forget.Impression for quality and build:First, and in principle, and subsequent impressions - if I chose "live" from many in the store - I would have chosen the same copy. Yes, and not the first and I hope not the last I have CASIO, there have never been problems with the quality. Live, as I will repeat the opinion of many - they really look better than in the photo, the photo does not convey them at all, I do not know what to call it - an aura? Charm?Cons: Weight. After CASIO efa-121d-1a weighing 150+ grams and even on a strap and not on a bracelet, this watch is absolutely not felt on the wrist. An unusual and not logical arrangement of the backlight button - at night, when I sleep, I always first press two protruding strips just above the button. The strap is a little harsh. Silent alarm clock - more precisely, it is not loud but sharp, shrill, and the repeat mode will probably really save if anything. So far, it wakes up normally - but again, there are not enough statistics.But all these minuses, as it seems to me, are "habit problems". In a couple of weeks it will be finally clear.Just in case, watch tests:Display testCASIO G-SHOCK TEST DISPLAYThis can help you determine if there is any damage to a particular display function that could prevent you from knowing if it is activated or not. It's also a handy way to see all the hidden display features built into your watch.To enter the display diagnostic mode:• In timekeeping mode, press buttons (A), (C) and (D) at the same time.• All display segments are activated.• Press (D) to view display test modes.• The last screen will show the Casio module number• Press any button to return to normal modeCASIO G-SHOCK TILT SENSOR DIAGNOSTIC MODEAll Casio auto-illuminated models use a basic tilt sensor to determine the position of the dial. If you are having problems with Auto-EL, you may have a faulty tilt sensor. Fortunately, Casio engineers have built in a tilt sensor diagnostic mode that can be used to diagnose potential problems.To access the tilt sensor diagnostics screen:• In timekeeping mode, press buttons (A), (B) and (C) at the same time.• TLT is displayed on the screen• The display will show “8888” when the sensor is activated.• Press any button to return to normal modeSolar Panel TestCASIO G-SHOCK SOLAR SENSOR DIAGNOSTIC MODEThe Rigid Solar G-Shock models use dedicated batteries and a set of small solar panels to maintain a charge. If you're having trouble charging your watch even in direct sunlight, you may have damaged your solar panels. To check the health of your solar panels, you can use the built-in solar diagnostic mode.________________________________________To access the solar diagnostic screen:• In timekeeping mode, press buttons (A), (B) and (D) at the same time.• SLR is displayed on the screen• The display will show “8888” when the solar cell is receiving light.• Press any button to return to normal modeIf the battery is fully charged, solar panels may not receive additional sunlight.CASIO G-SHOCK ENERGY SAVINGAnother great feature hidden in the Casio G-Shock manual is the ability to automatically conserve power when not in use. The power saving function will automatically turn off the display after 60-70 minutes of inactivity. In this sleep mode, all other watch functions (including alarm and radio sync) remain active. After 6 or 7 days of inactivity, the watch will enter deep sleep mode, which will disable automatic reception, beeps, tones, backlight and display.________________________________________To turn on power saving mode:• In timekeeping mode, press and hold button (A) until the area code flashes.• Press (C) nine times until the power setting screen appears (PS is displayed).• Press (D) to turn on or off• Press (A) again to install and exitG-SHOCK AUTO LIGHT MODE ONThis is probably one of the more well-known hidden features of the Casio G-Shock, but still one that many people are not aware of. Most G-Shocks with a backlight function actually have an “auto-backlight” mode, a great feature that automatically lights up the watch when it's tilted 15 degrees towards your face. While this feature is known to drain the battery faster, it is smart enough to shut down if the watch goes below full charge. In addition, the feature will only remain active for six hours before having to manually reactivate it.To turn on auto light:• Hold button (B) for 3 seconds.• The wording “A. El 'will appear on the dial if successful.• Press and hold the button (B) for 3 seconds to manually shut off, otherwise it will automatically shut off after 6 hours.I'm not attaching a photo yet, there are so many of them ;)

Watch has every function that I need, with loud, audible beeps when you switch between modes, and a different tone/beep when you reach the main screen. I like the fact that I can easily see a second time zone, as I have family out of the country and need to know when I can call them. The watch is a little smaller than I had imagined it would be, but it is completely functional, high-quality, will never need a new battery or the time adjusted. Basically, it does everything you need it to without doing things you don't want it to and without an insane price tag. Overall, great value to function ratio that is easy to use and packed with features.

The order shows Casio G-Shock GWM5610-1, but the watch back shows GW-M5610U. Sold by Amazon. Sold as new and received in new condition.SUMMARY: I have given the watch a rating of 5 because it does what is stated in the manual (qw3495.pdf, on the Casio site). The watch is not entirely satisfactory for me; I assumed more alarm capability than this watch has.PRO: Shock and water resistant. Light button recessed. Solar power. Time setting automatic. Resin band comfortable and easy to clean. Watch has 5 alarms.CON: Watch could snag on things. Numerous button presses may be required for settings. Gaskets should be replaced every 2-3 years. Unobstructed bright-light time needed to keep the battery charged. Alarms daily only; cannot be set for a specific date. Band durability uncertain.Shape and Appearance: The watch face looks nice and practical. The watch is rather wide. The watch is thick, but the design makes the thickness less noticeable. The watch is large and somewhat angular, so it could snag on things. The width, thickness, and angularity probably improve shock absorption.Buttons: The buttons are slightly recessed, which is good.(I want to conserve battery power, so I don't want to turn on the light accidentally, for example while putting on clothing or putting my hand in a pocket.)Because the watch has only 4 buttons, entering settings and alarm times can require a number of button presses.(I also have owned Casio calculator/databank/alarm watches that use 8 buttons to control settings, including the reverse, forward, 0, and PM buttons, and use the numeric keypad for setting times and dates.)Water Resistance: Having only 4 buttons makes water resistance more practical. The gaskets are supposed to be replaced every 2-3 years, maybe by an authorized CASIO service center.(I doubt that I will bother to have the gaskets replaced. My Casio calculator/databank/alarm watches have not been water resistant, presumably because of their numeric keypads. My most recent DBC-32 watch probably stopped working after 7 years because I had washed the watch many times -- my mistake.)Solar power: Powering the solar cell requires a moderate amount of bright-light time. When the watch is charging, no part of the watch face should be covered, for example, by a shirt sleeve.(I usually don't spend a lot of time outdoors, so when I first bought the watch, I occasionally propped it on a windowsill, using the plastic stand on which the watch is shipped. I later realized that keeping the battery charged has not required extra effort. The watch probably gets most of its charge when I drive, up to 3000 miles per year. The solar cell requirements are detailed in the manual; if the watch gets some sunlight, I think the manual's estimates may be pessimistic.)Band: I think the resin band is comfortable, and it stays clean. Metal straps would yank on my arm hairs. Unbuckling the wrist strap is easier because the metal prong has enough weight and free motion that the prong can fall out of the way when it is pulled out of a hole in the strap. The manual says that the strap should be fastened loosely enough that you can insert a finger under the strap, but photos show that many users fasten their straps tightly. The keeper (the resin loop that holds the free end of one strap against the other strap) contains a cutout slot. When I slide the keeper over the free end, it sometimes snags on that slot. I hope that Casio will remove the slot or make it short enough to prevent snagging.(I have used Casio watches for 40 years. The resin straps have broken on the majority of those watches, after years of use. I have been careful to limit bending and pulling on the straps of my most recent calculator/databank/alarm watch, especially when putting the watch on and taking it off, so there is no sign of cracking after 7 years. I cut off most of the bump on the free end of the DBC-32 strap, to reduce stress on the keeper. I don't know if Casio has improved the band durability. I think the bands ideally would consist of nylon or Kevlar fibers running lengthwise, covered by resin.)Alarms: Although the watch has 5 alarms, I can specify only hours and minutes, not months and days. In other words, the watch only has daily alarms, not yearly alarms.(I need to be able to set each alarm for any particular minute during the next year. Again, I should have read the manual before buying.)Automatic Time Setting: This feature works for me; it is impressive. After automatic time setting, any discrepancy between the watch time and time.gov appears to be less than 0.1 second -- that is, less than I can perceive by eye.

I am a watch collector and I really appreciate analog watches, but I do love a quartz digital for casual and work wear. The 5610 is by far the greatest digital watch ever made and arguably the greatest watch of ANY kind.It's small (by G-Shock standards) and so light you barely know it's there. It has nearly every conceivable useful digital watch feature--alarm, timer, stopwatch, etc. But I was specifically interested in the solar charging and world timer functionality, which let's you store 5 zones at a time. I love that in world timer mode, it keeps home time on the same screen so you always know what time it is at home at a glance when out of town.Given all of these features, they could have made it confusing to use, not the controls are very intuitive and based on the same wonderful Casio button functionality. And, it's a G-Shock, so it's basically indestructible.I gave it 5 stars because I couldn't give it 6.
