I am very happy with this watch, solar powered so should not have any battery issue for a very long time. I wish the Radio time synchronization was also possible in the Southern Hemisphere as I visit there occasionally. When setting the radio sync - remember to set the Day Light Saving correctly - the watch did not want to sync properly until I did that. The Tide function is nice, I have it set for the closest area to me, I will try the feature at some point where you set it for exactly where you stay, and not relying on the cities they have programed into the watch. The count down timer is nice, I have set it for an alternating 3min/1 min for 10 repeats for when I am training on the Spinning bike.Moon phase display is very accurate. You can see the time in different cities too - also nice.Personally I would have preferred a less colorful strap and case. I would have liked something that had the features but more stealthy/muted moon data information of 100 major tide points in the world is set in advance, you can surf in the sea around the world Such a cool watch.-From Japan. This model isn’t sold here.-solar and atomic, tide graph/moon phase all in a 5600!!This tide graph is way more accurate and ‘settable’ than my Casio G7900. Especially for the west coast. You can program the exact time of the first high tide of the day
