Pro's:
1. 5 alarms with one of them having a snooze option.
2. Moon Phase and Tide forcasting, you can advance to dates in the future on the moon screen and can view the tides of that day (I can predict the tide on a specific future date).
3. You don't need to hit any buttons to determine the current tide/moon phase.
4. Countdown timer, some casio's do not have this option, but this one does.
5. Dual Time Zone.
6. Sun Compass (show you an angle and you line the sun up with the angle and you can determine where North is). Each dot/mark on the watch is 6 degrees.
7. Every screen but the stopwatch show the current time.
8. Stopwatch has split times (however not reviewable - see cons)
9. Band is very comfortable with a strong buckle and is not bulky.
10. Pretty good instructions, good detail, shows the options.
11. The Price is great, other comparable watches (with good brand names) with these options run around $60.


Con's:
1. I wish the booklet or a website provided the lunitidal interval for most beaches as this value slightly differs from location to location. The Lunitidal Interval is a delay between the moon at the middle of its rise/set and the following High tide. It is needed for the watch to display accurate tides.
2. The countdown timer can only be set to minutes. I can set it to count down from one minute, but I can not set it to count down from 20 seconds.
3. The band where it connects to the watch body cannot rotate past a certain point. This means that it is always in a circular arrangement and not as comfotable as it could be in a pocket. It can not be flattened
4. I wish the light was an indigo light instead of the bulb light.
5. I wish the lens was a little better protected by the outer rim. I hate scratches (no watch is perfect in this regard).
6. The indicator that shows if the alarm is armed is a little difficult to see - but it can be seen.
7. Seems to be about 4 fast after a month.

My con's are more a bit of whining. I love this watch. I purchased this watch for a specific purpose, but now I wear it all the time. Great look, very comfortable, very useful.

The watch is large and looking cheap. It can be as large as Casio G-shock. The manual's disclaimer says the watch's features (i.e. azimuth angle) are not designed for real life situations (no use, for fun only). The face seems very easy to be scratched. I paid $20.19, not worth it, in my opinion. 2 stars

This great little watch does everything its advertised to do for a reasonable price, but has one big flaw. The four large set buttons are exposed in such a way as to be inadvertently bumped and changing the function which happens all the time. Its especially bad when using the dual time function, when an accidental bump to either of two buttons actually changes the displayed time in half hour increments. This can easily cause the missing of an appointment. 2 stars

the only real complaint I have for this watch is that I can't see the date!! The window for the date is right below the "12", but it is SO small that I can barely read it. I guess I would also have to say that the watch is VERY unfeminine, and I bought it because it was advertised as a Ladie's. It's as big as any man's I have seen, and the black rubber strap is purely functional, this will never fall off. I tested it extensively diving in the waters of Hawaii over two weeks, it looks brand new despite rugged conditions. I bought it primarily for the tide keeper function, as a shallow water sailor that matters a LOT to me, and for that funtion it is perfect, the dial is easy to read, understand, and use. I would recommend this brand and product as long as you're more into function than style. 4 stars

I needed a watch to perform basic functions like countdowns, timing of laps in swimming and running etc. I have found that it was easy to set but it took a little time to turn off the alarms and set the tide function. Once those were set I have been very happy with it. It's nice to have it water resistant. 4 stars
