Casio Waveceptor Watches WVA-M640 and WVA-M630 In-Depth Review

Описание: This episode of the Atomic Timekeeping Show is an in-depth review of some Casio Wave Ceptor watches, including the WVAM640 which is readily available from U.S. retailers. I also show off a few variations of the WVA-M630 which is available from sellers in Japan. All of the watches featured in this video (except one older model which I clearly identify) use the same Casio module 5161, so they have the same features and functions. The only real difference between the various models are color combinations and watch band and/or bracelet variations. One of the featured watches even has a titanium watch band for improved comfort and light weight.

These watches each have Casio's "Tough Solar" technology. The face of each watch contains a solar cell which automatically charges an internal battery with normal exposure to normal amounts of daytime lighting. My first "Tough Solar" watch from Casio is still running strong after more than 12 years without ever having to worry about replacing its battery.

These also have Casio's "Multiband 6" technology to receive Atomic Time data from up to 6 transmitters in various parts of the world. There's one in China, two in Japan, one in North America, one in the UK and, finally, another one in Germany. If you are using this watch in a part of the world which is too far away to receive the data from those transmitters then the watch will function as a normal quartz watch with accuracy to within a few seconds per month. But if you are in a place where good reception of Atomic Time data is successful, then your watch can double-check itself every night and keep itself accurate to within fractions of a second all the time! It can even make Daylight Saving Time changes automatically.

As you can tell, in my quest for good timekeeping, these watches are among my favorites.

Casio also sells various versions of the LCW-M170 and LCW-M100 in it's "Lineage" like of watches. These also use the same module 5161, so you can use this video as a reference to discover the same functions of those premium watches. Lineage watches often use more titanium in their cases and feature sapphire crystal for improved scratch resistance. The watch faces also have a less-cluttered, more "high-end fashion" look.
