If the main hands point to 12 o’clock that means there isn’t sufficient light to charge the battery. At 6 o’clock, the watch is getting “optimal light.” When outside, you are good, but in most rooms at night unless under a lamp, I find that the watch will not receive enough light to charge. So be sure to take it outside sometimes.

Putting all the functionality together, the features of the Citizen Eco-Drive Satellite Wave F100 make good sense and aren’t complicated to use. With that said, as times goes by, it is easy to forget how everything works – especially if the Citizen Eco-Drive Satellite Wave F100 isn’t your only watch. I’ve certainly had more confusing Citizen watches, but my advice to you is to read the manual to understand just how the Citizen Eco-Drive Satellite Wave F100 works.

I’ve said good things about the design, explained that this is a product where reading the manual is a necessity, and talked a bit about the competition. So at the end of the day, how do I feel about Citizen’s best foray yet into the GPS-controlled watch market? I first want to say that I think this market is developing. Citizen and its competitors are targeting travelers and gadget lovers, since gone is the day when without mobile phones timepieces were your sole way of checking the time. Having said that, a good argument (for me) for a watch like the Citizen Eco-Drive Satellite Wave F100 while traveling is that it will be easy to know the time where I am, and I can preserve mobile phone battery life by not constantly having to look at it just to know the time. I say that as someone who already wears a watch all the time anyways, but I do truly feel that if someone is on the fence about a product like this, there are reasons for it aside from the “coolness” factor.


It is a cool watch, and it is one I like. In fact, I found myself liking the Citizen Eco-Drive Satellite Wave F100 watch a lot more than I thought I would. I should rephrase that; I knew that I liked it as I’d handled it in the past, what I learned is that I really enjoyed wearing it. In a time when mechanical watches win the hearts of most watch lovers, it can be an amusing refreshment to pick up a watch in your collection that doesn’t need to be wound, doesn’t need to be in a winder, doesn’t need to be set, and can easily be relied upon, assuming it is exposed to enough light and is taken outside every once in a while (even when not GPS synced, the accuracy of the watch should be like other standard quartz movements which is about plus or minus 15 seconds per month).


What really tipped the scales in favor of the Citizen Eco-Drive Satellite Wave F100 was its style. Whereas the competitors are pretty thick and large and not particularly elegant in style, Citizen has something with more of a dressy appeal and refined elegance. What I see is a gadget that not everyone looks at and says “that’s just a gadget.” Design and beauty are certainly important – especially when it comes to a watch. While I still don’t think you can wear most G-Shocks on a date, I think a lot of people can easily get away with wearing a Citizen Eco-Drive Satellite Wave F100 when trying to blend in with colleagues or impress a lady.

While not without a few quirks, the Citizen Eco-Drive Satellite Wave F100 is an exemplary high-end quartz watch with a very useful movement and a design that your mother can love. I happy to think it is pretty attractive as well, and see myself getting a lot of use out of it until Citizen comes up with something even better. Price for the Citizen Eco-Drive Satellite Wave F100 ref. CC2006-61E is $1,800.
