5.0 out of 5 stars A Solar Watch For the Minimalist In You 9 Jan. 2013
By My Own AMZN - Published on
Verified Purchase
My other solar watch starting resetting itself three times in 24 hours so I decided it was time to get a replacement when I came upon this batteryless watch. Instead of using a battery that gets charged by the solar cells, this watch uses a capacitor. When the capacitor is fully charged there is enough power to run the watch in total darkness for 14 days. The use of a capcitor instead of a battery sounded like a novel idea, but actually a "relative" of this watch, the Casio AL-180 was created back in 1987.

The watch is RETRO in looks and operation and reminds me of when LCD watches first came into existence. It has the tiny silver buttons, no LED backlight, no automatic daylight savings feature and no automatic leap year. For daylight savings and leap year, one needs to manually make the settings. Very old school (like back in the early days of LCD watches) which I think is part of this watch's charm.

However, this watch does have alarm/chrono functions with 5 alarms, plus hourly chime, 24 hour countdown timer and 1 hour stopwatch.

Initial Charge
I received my watch in the evening. Since it was dark outside I decided to charge up the watch using artificial lighting. I have a task lamp with an LED light bulb (that screws into a regular incandescent fixture). Since the watch's power reserve was low, a low power icon that looks like a sun was showing up on the watch's LCD display. The goal is to expose the solar cells long enough to light so the icon goes away. Since I was using an LED bulb which there is very little heat at the surface of the bulb, I placed the bulb about 1.5 inches away from the watch and left the light on overnight (about 8 hours). By morning, the low power icon had disappeared.


- solar power, battery-less
- retro look
- easy operation
- great price
- includes stopwatch, countdown timer, 5 alarms plus an hourly chime
- countdown timer can be set up to 24 hours
- easy to charge with artificial lighting


- no LED backlight (but this is not a deal breaker for me)
- display window tiny compared to other watches
- stop watch can only go up to 59 minutes, 59 seconds (but one can use the countdown timer as an extended stopwatch, in a sense. See the "geek alert")
- low power indicator only has one icon symbol (not H-high, M-medium, L-low)

** geek alert -- tip on using countdown timer as extended stopwatch **

If you are satisfied with only a 59 minute, 59 second stopwatch, then you can skip this section. But if like me, you want a longer stopwatch time, then read on.

I was disappointed that this watch only has 59 minutes, 59 seconds as the maximum amount of time in the the stopwatch function. But, by math, one can actually use the countdown timer as a stopwatch by subtraction. The idea is to think of hours and minutes instead of just hours on the countdown timer. I set my countdown timer to 11 hours. 11 hours is the same as 10 hours and 60 minutes. So, let's say you want to time something that takes about 2 and a half hours. I can start the countdown timer which counts backwards from 11 hours. When the timing stops, you stop the countdown and the watch shows 8:15 (8 hours, 15 minutes remaining). By math (10 hours/60 minutes minus 8 hours/15 minutes leaves 2 hours/45 minutes which is the total elasped time for the event. Note: I chose 10 hours/60 minutes as the start as that is just easier math. But for longer durations, one can choose a larger time to start from (for example, 23 hours, that is 22 hours/60 minutes). The math isn't really that difficult if one thinks in terms of hours and minutes instead of only hours as the starting point.

** end of geek alert **

In conclusion, I really like this watch. It doesn't have an LED backlight, but the watch is simple and retro. Plus, being solar and batteryless, should last a long time.

Everything old is new again.

Update (2/10/2013): I've owned this watch about a month and it works as good as new. After the initial charge when I first got the watch, the low power indicator hasn't turned on even once.

5.0 out of 5 stars A watch that lasts forever? 4 Jun. 2012
By Martin - Published on
Verified Purchase
I've had this watch now for a couple of months. I got the watch because I wanted something that will last a really long time without any maintenance. I had an automatic mechanical watch that died after only a couple of years, and battery-based watches (including solar watches with a rechargeable battery) last about the same as well, but this watch is supposedly "batteryless" (capacitor-based). I will try to update this review after a few years, though it probably won't be for sale at that point!

Upon arrival, the watch was completely discharged and it would die after a moment of dim light, even after being outside for 15 minutes or so. I taped the face to a fluorescent light fixture overnight and the next morning it worked great, and I have never gotten the low battery icon since. The watch face's crystal has been tough enough to withstand some abuse by my cats. The time seems to drift by a few seconds every month but is easy to recalibrate as the time will round to the nearest minute when the seconds are reset. As noted in another review, the watch has no light built in due to the small power reserve, though it does have alarm functionality (loud enough to wake me up, not loud enough to hear at a very noisy party). The watch band is the worst part. Though soft and smooth to the touch, it traps moisture despite the vents and the strap isn't held tightly enough by the sliding loop. Plus, the buckle is plastic rather than metal. I preferred my previous watch's removable links for a custom fit and hope to get a replacement band with a similar style (black ceramic links perhaps?) I didn't go for the metal version of the watch (AL190WD) because the module is actually metallic plastic and the band doesn't have removable links.

Overall, so far I feel this watch is a great value and I believe it will last a long time.

5.0 out of 5 stars Excellent cheap watch. Get a better band for it. 8 Mar. 2013
By Me - Published on
Verified Purchase
I have now owned this watch for almost a year, and I love it. It keeps time accurately, easily meeting the manufacturer spec of 1 second per day deviation. The case and face are tough, and even after banging it around for a year there are barely any visible scratches. The watch is very light weight, which was something I was looking for.

Many supercapacitors are rated for 30+ year lifespans, so it is my expectation that it should last me as long as I'd like to keep using it. You'd have a hard time finding another watch capable of lasting so long with no maintenance at any price, let alone under $20.

--The band--

The main problem with this style is the band. The cheesy plastic bands on these Casio watches always irritate my skin, trapping moisture and making wear very uncomfortable. Even stainless metal bands found on higher end watches cause these problems for me.

In an attempt to solve this, I outfitted this Casio with a NATO "tropical" style woven strap (the correct width for this watch is 18mm). This type of strap has a loose weave which lets moisture through as well as a having a piece of the strap which sits between your arm and the back of the watch case (another source of skin irritation). The replacement strap solved all my problems; now I can wear this around all day and forget I have it on.

My advice is to not skimp on the band. The band that I purchased for this watch cost more than the watch itself (I paid $23), but I think it is worth it. The quality replacement band makes a huge difference in comfort.

--Initial charge--

When I initially got this, I thought it was broken because it didn't seem to hold a charge. I placed it under a lamp and let it sit there for hours, but when I took it off it immediately reset itself when out of the light. I believe that the cause of this was that the light was heating up the watch too much. After setting the lamp to low power and letting the watch charge again overnight, it worked perfectly.

Since then I have found that a good way to recharge is to simply place the watch under a CFL table lamp for a few hours.

--How long a charge lasts--

This watch, sadly, is not magic, and you do need to expose it to sun every little while for it to stay charged by itself. A few minutes of direct sunlight every few days is enough to keep things going, but if you have a week or two of dark rainy days or staying mostly inside you will get the charge indicator. Based on my observations, I believe that typical indoor lighting is just barely not enough to keep the watch charged indefinitely.

--No light--

I figure I should probably mention, like everyone else, that this watch does not have a builtin light. The engineers at Casio probably figured it would make it too easy to drain the capacitor. Regardless, I have personally found that it is not a big deal. My other watches (analog variety) do not have lights either, and with a small light on my keys it is easy enough to pull that out in the rare case that I am in total darkness and need to know the time. A light turns out, for me, to be something you would think you need but I really didn't.

--LCD contrast--

This one is a nitpick, and it only bothered me for the first week or so of using the watch. Looking at the LCD from at all 'above' the watch, that is, with the bottom part of it tilted away from you and the top part tilted towards you, the numbers will start to look gray rather than black. This is exaggerated when the charge is low. It is not a big deal, though.

--Water 'resistance'--

I haven't gone diving with this, but I have exposed it to varied amounts of dynamic water pressure, and it has not leaked. Even though people say a "50 meter" watch should not be used for swimming, it seems fine for it for me.

UPDATE: I melted the plastic part of the face a bit with bug spray recently. This is certainly a downside to a plastic watch; be careful when applying sprays. The watch is still functional of course, the plastic surface is just rough now.

Works as described. EXCEPT THERE IS NO LED LIGHT.
Someone should edit the product details.
Cheap, don't need to worry about batteries. Just make sure you leave it in the sunlight when you first get the watch.

5.0 out of 5 stars worth buying 10 Oct. 2012
By surya - Published on

It was first online purchase, that too... international shipping to India,
Pleasant surprise, they promised to deliver in 2 weeks & made it in 1 week.

I left in window sunlight for 7-8 hrs, but the low charge indicator did not disappear &
the screen went blank when i took it away from light .... i thought it was defective.
That night I tied it about 2.5 to 3 inches close to a common fluorescent light.
The next morning, the low charge indicator has gone & time keeping is normal.

the watch is very light on wrist, its simple,
displays day & date, regular time.
If you check other brands, you could not get such a eco friendly watch at this low price. thanks to casio.
