Here’s my review of the DW 5600E-1V, a Casio g shock wr20bar.

Casio G shock DW 5600-e 1v 20BARWR


The Casio g shock wr20bar DW 5600E-1V is one of the most robust and cheapest WR20bar G-Shocks you can buy today. It costs only $ 51.99 on Amazon at the time of this writing, and it’s excellent as an everyday wear watch.

 I’ve worn it for over a year so far, and it’s held up great in all circumstances. In the summer on the beach and throughout the winter in the cold. It’s fair to say that I love this watch :-)! 

Who would have expected that for such a cheap watch?! 

I certainly didn’t. 

As a matter of fact, I was never a fan of G-Shock watches. Most of them were way too big for my small wrist, and I didn’t consider them very classy.
This is a short introduction of the Casio g shock wr20bar DW5600E-1V.

To me, G-Shocks were purpose watches to be worn by “wiry” guys like builders, marines, and craftsmen. Definitely not suited for guys like me who spent their days behind a computer in an office setting.  

And how about an elegant night out? Forget it. No way you’re gonna slip a bulky G-shock under a shirt’s sleeve or wear it with it a suit. It looks ridiculous. 

I agree. For most G-shocks, it does look a bit ludicrous. But not for the DW 5600-E 1V. 

With a size of 45 mm and a relatively short lug to lug distance, the DW5600-E 1V wears nicely without looking too big, even on smaller wrists. It also looks OK with a suit or formal wear if you use complementary colors. Make sure you dress well, don’t wear too many colors (and don’t look like a clown), and you’ll be fine. 

The DW 5600-E 1V is the smallest G-Shock for men on the market today and a direct heir of the first G-Shock, the DW-5000C, released in 1983. Like the DW-5000C, the DW5600-E 1V is WR20bar (more on that in a minute). 

As said, I’ve worn it for over a year, and I can only say good things about it. Sure, it may not be the right watch for everybody, and many people buy G-shocks as a second watch. But in case you only have one watch, and it’s the DW5600-E 1V, you can use it as an everyday watch without any problem. 

Before we move on, here are the specs of the DW5600E-1V: 

  • Shock resistant: YES! Like all G-Shocks. 
  • Module: QW 1545 with digital display. 
  • EL backlight with afterglow. 
  • Case diameter: 45 mm. 
  • Case/ strap material: polyurethane resin. 
  • Timekeeping function. 
  • Alarm mode. 
  • Countdown Alarm mode. 
  • Stopwatch mode. 
  • Scratch-proof mineral glass case. 

You can download the official DW5600E-1V manual from Casio’s website here

Mind you: the DW5600E-1V is as basic as it gets. If you need more bells and whistles like Bluetooth and solar power, choose the GW-B5600HR-1JF. Link to here

What does WR20bar mean? Is a G Shock WR20bar like the DW5600E-1V waterproof? 

Yes, it is. WR20bar means that the DW5600E-1V has a water-resistance of 200 meters or 20 bar. This means that you can use it while snorkeling, Scuba diving or deep-sea diving, though you’d be better of using a real dive watch in those cases. 

For regular swimming, the DW5600E-1V is perfect for in the sea or in the pool. When swimming in the sea, make sure you rinse it with fresh water after afterward, to avoid damage from saltwater. 

How to prevent g Shock resin rot? 

You should also avoid exposing your DW5600E-1V for prolonged periods to UV rays to prevent resin rot. Resin rot happens when the polyurethane resin of the watch decomposes, causing the band and case to deteriorate and crumble. But since it can take decades before this happens, I wouldn’t worry about it. 

From comments I found in watch forums like this one, it seems like resin rot is a real concern for owners of G-Shocks. 

It’s hilarious, in my opinion. Here we have a bunch grown up men, spending their time discussing possible damage to a $ 50 watch as if they were talking about protecting their $ 45,000 investment in a Patek Philippe 5738R – GOLDEN ELLIPSE against a drop in the global gold price. 

Forget it. 

Just wear your G-shock and buy a new one in case resin rot occurs. 

Let’s move on. 

How to adjust your G- Shock DW5600E-1V? 

There are 4 buttons on your DW5600E-1V: 

  • Top left (button A);
  • top right (button B);
  • bottom left (button C) and; 
  • bottom right (button D). 

To move from mode to mode, press button C. 

After performing any operation in any mode, press button C to return to the timekeeping mode. Press button D to illuminate the display of your G-Shock. 

Set the time and date. 

  1. Press button A while in timekeeping mode. The display now starts to flash. 
  2. Press button C to change the selection. The sequence for changes is Seconds -> Hour -> Minutes -> Date -> Month -> Year. 

Set a daily/hourly alarm

Setting a daily/hourly alarm on your DW5600E-1V is handy to remind you how much time you spend on a task. 

Here’s how to set it.

  1. Set the hour and minutes for the alarm time. 
  2. Set “-” for the month and “–” for the date.

This causes the alarm to beep every day at the time you set. 

If you want the alarm to beep at a specific date, set the month, day hour and minutes for the alarm time. This causes the alarm to beep on the set date/time. 

My experience with G-shock DW5600E-1V after wearing it for over a year.  

Great wearing comfort 

G-Shock WR5600-E 20BARWR
The DW5600 easily slips under a shirt sleeve.

As mentioned in the introduction, I’ve been wearing the DW5600E-1V for more than a year. 14 months to be exact. What I really like about this watch is the wearing comfort. The resin strap is really smooth and easy on the skin, and although it can get sweaty, it’s easy to adjust the strap and wear it a bit looser around your wrist. This way, air passes around your wrist easier.

What I also like is that the DW5600E-1V is rectangular. When I first tried it on, it immediately felt “right”. The rectangular shape gives the watch a very natural fit on your wrist. It’s very different from a regular round watch. 

Because of the small size of the case, there are no protruding parts either. This makes it easy to slip it under a sleeve. 

The DW5600E-1V doesn’t shout “G-shock” either. For a G-Shock, it’s a modest watch. Not too small and not too big. It also has that classic “1980’s digital watch” look. This is how digital watches are supposed to look, in my opinion. It’s a bit like the one Marty Mc Fly wore in Back to the Future :-).  


The legibility of the display is not very good in intense light, but that’s the case for all digital watches. Therefore I don’t consider this to be a DW5600E-1V- specific problem. You can always choose a G-Shock with an inverted display (like the GW-M5610 ) if legibility is a concern for you.

The lume is OK, although it lasts only about 3 seconds.

Easy to clean 

Since the resin material doesn’t absorb any sweat or water, it is easy to clean. After a day in the sun, I usually rinse my watch in fresh water and dry it with a soft cloth/towel. 

In general, I would advise you to rinse your DW5600E-1V from time to time to prevent sweat from building up on the case back and strap. This is sweat that dries up and builds “crust” on your watch. In case your watch is affected by this, you can give it a gentle clean with some mild liquid soap and a toothbrush. 

Easy to change batteries 

In case you need to change the battery of your watch, it’s easy to do it yourself. Check out this video to see how. The battery in your DW5600E-1V should last for 2-5 years ex-factory; however, there have been reports of people using G-shocks for 10+ years before the first battery replacement. 

DW5600E-1V battery type

The DW5600E-1V uses a CR2016 type battery. These batteries are cheap on Amazon

Are G-shock watches any good? 

This is a general question I found on Google, and based on my experience with the DW5600E-1V, let me try to answer it here. 

For what it’s worth, I think G-Shocks are VERY GOOD watches. There are no cheaper or more expensive watches on the market today that are as robust and reliable. Period. What’s more, a G-Shock is more accurate than the most costly mechanical watch you can buy. 

How long do G-shocks last?

A G-Shock can easily serve you 10 – 15+ years with proper care. You’ll probably have to change the batteries and the strap every so many years, but that’s it. 

G Shock WR20bar fake vs. original 

Another general question I found on Google. The easiest way to spot a fake G Shock WR20bar is to check the back of the case. If the word “Casio” is not mentioned, this means the watch is fake. Check this site for more indications of a phony G shock WR20bar. 


I’ll wrap up this review of the Casio G-shock DW 5600E-1V WR20bar by saying that I HIGHLY recommend this watch. The wearing comfort is excellent, the watch is very solid and reliable. It can take more than a few knocks without any problem, and it can be worn on many different occasions. 

Whether or not you think it’s worth $51.99, I leave up to you, but I definitely think it is. 

If I were Tom Hanks on a deserted island and could choose just 1 watch to wear, it would most definitely be the DW5600E-1V WR20bar. 

You can get yours here on Amazon. 


I'm Leon. I write articles about small watches (usually 38 mm or less in diameter) because I like them. They look stylish and classy to me. Most of the watches on the market today are 40 mm or more, which I think is too big. This blog was born out of curiosity when I was shopping for a small watch myself and couldn't find the info that I needed.
