wave ceptorCasio Japan WVA-M630D-7AJF - Watch for Men, Bracelet, Bracelet

Easy to read dial and a nice looking watch. I did ruin one by wearing it at a water park, my fault (water resistant not water proof). But my favorite watch for everyday wear. The one I messed up had been in rain, mud, and still looked and worked like new after 2 years. Once you set up your timezone these just work. Adjusts for daylight saving time automatically, it adjusts the time on its own so it always matches my phone. And it's solar, so it's aways at a full charge. The dial has luminous hands and also a small light if needed for nighttime use.

This is my first wave septor watch, I love it and would buy again! There is one thing though that can't let me give it 5 stars. Read on...First, the good things.1. Timekeeping. Once the timezone is set, the watch synchronizes every night, or you can initiate a manual sync. I sleep with my watch on, and it syncs just fine (I live in greater Seattle area). So, it's set and forget, you don't have to ever care about adjusting time of your watch.2. Solar power. Works just fine. It has been just a few weeks, but I have yet to see anything other than "HI" (ie fully charged battery). This watch has advanced power management built it -- for example, if it's in the dark for long time (like, a night), the seconds hand stops ticking, and the digital display is turned off to save power -- still, analog hands shows the correct time. Once you press a button, or expose watch face to some decent light, it turns back on instantly (and it's a pleasure to see the seconds hand move quickly to the correct position).3. Glowing hands and backlight. Both works fine. The luminescence of hands lasts through the night, which is important to me. Just in case it's not, there is always a LED backlight. Surprisingly, I like the amber color of it. Note that the backlight does not help you to read digital display, but I don't see it as an issue. But there's one thing that bugs me -- scroll down for negatives.4. Design. Nice size (not too big, not too small), very readable, clean face.5. Mineral glass. Yes, it's not sapphire (you can have a sapphire crystal, too, but not for under $100 -- look for Casio Lineage 170 or higher), but so far I have yet to see any scratches on the glass.6. Hands precision. Hands are very well aligned to face marks, a perfectionist in me loves it! The manual says that in case it's messed up (say by a strong magnetic field or a hit), you can readjust it. I haven't tried it as there's no reason to do so, but it's nice to have this feature just in case.Now the bad things. In fact, just one thing -- everything else is minor nuances.1. All 12 hour marks have same luminescence dots (see the photo -- you can't figure out what time it is from it, can you?). Usually, 12 o'clock is marked with a different symbol (either double dot or line, or a wider/bigger dot) so you can see where's 12 when it's dark. This really bugs me (especially the aforementioned inner perfectionist), and this is the reason why I give it 4 stars.2. I didn't quite like the original band -- you can't remove extra links, they just hide beneath the bracelet making it slightly thicker on your wrist. It is a very minor issue as you can easily switch to any 20 mm band you like, and this is what I did. Again, this is not an issue.3. Lack of English manual. I do not understand why people slash a star because of it. This model is clearly for domestic (Japan) market, so it's sort of "gray import" and it is fully expected that it comes with a manual in Japanese. Just Google Casio 5161 manual (here 5161 is watch module number, as engraved inside a rectangular box at the back side of your watch). Again, this is not an issue.

This fantastic watch is still going strong on the original solar-powered battery 10 years after I got it. It keeps absolutely perfect time and needs no maintenance whatsoever. A very useful - and very rare - feature is the strap design that doesn't require a visit to a jeweller or the purchase of an adjuster tool to make it fit any wrist size. Need I say more?

My old watch was looking rather tired and had begun to occasionally irritate my wrist due to its bulk, bandfit, and my aging skin. It was also old enough that its digital display lacked lacked the contrast of newer watches I had seen. I briefly looked at Seiko, but between the added cost and uncertainty about how "kinetic" I was in my senior years, I deferred. After checking out Costco, I was unable to find an appealing stainless clasp band with a legible non-busy face with radio correction. After realizing how convenient and flawless that my prior waveceptor had been, I focused on Casio's latest offerings via Amazon. The convenience of no battery changes and automatic DST corrections made for a maintenance free watch. The black numerals on white background make for a highly legible readout, and the band is slim and strong, with the watch case about 2/3 the thickness of my old waveceptor, making for a barely noticeable feel. The cherry on top was that the watch as delivered fit my OVER- sized wrist without adjustments, and is adjustable without adding/removing links. Bonus features include night glow markings and a handsome lookI am extremely pleased with this purchase.

I love solar powered watches. Never a problem. This watch is solar but automatically sets time from a radio signal. I never was able to get the watch to set to my local time. Followed directions but they never worked. Sent it back. Otherwise a nice watch.

This is a replacement for a Casio Waveceptor that ended up in the wrong side of the sink disposal. Delivery from Japan was expedient via Japan and United States Postal Services. The included instructions were in Japanese, but also included a document (Or do a Google Search) on how to find the English Instructions. The 630 series watch is a bit less complicated and lacks a few un-necessary features, but is easier to operate. The watch arrived with a medium charge, so I gave it a few hours in the sun and it was fully charged. After configuring the proper time zone, I let it spend the night in the window and the next morning it linked to WWVB and calibrated to within milliseconds.The solar power source is great, no batteries to drain, even when using the nightlight. I specified the easier to read Arabic Numerals on the face. Casio went to a different wristband adjustment mechanism and you won't find the adjustment instructions on You Tube or the Internet. Even if you did, you'll need the right tools to remove the locking pin.I work with small electronics and I ended up not attempting it. Take it to a watch repair jeweler, pay them a few $$ and have it adjusted in two minutes. I'm an engineer and am almost clinical regarding clock accuracy, I don't believe anyone other than Casio can provide such an accurate and quality timepiece for less then $100.00.
