I haven't purchased a watch with a quartz movement for many years but I really wanted this one. I think mechanical movements (particularly self-winding automatics) are much more elegant and represent true craftsmanship; however I wanted to have a chronograph and, a mechanical one, due to its complexity, is too expensive for me; they typically cost well over $1000 for the least expensive decent one. I have viewed many, many quartz chronographs over the past month or so and I like the looks of this one the best, and bonus, I'm a US Navy veteran.Besides the great looks, I really like the solar powered movement (who wants to replace batteries?), perpetual calendar (a mechanical watch with a perpetual calendar would cost over $15K easy), and the automatic synchronized time features. My watch won't synchronize unless I stick it by a window but so what? It's a quartz movement and will be only off by a couple seconds in a months time before I sync it again. The power reserve indicator, automatic daylight savings time adjustment, and the ability to switch to any other time zone are also nice. Also, I really like sapphire crystals like the one on this watch because you don't have to worry about scratches. Quite frankly I don't really need many of the other features of this watch, including the chronograph function (if I did need it, I might mind the lack of capability to measure split times). I don't really see the usefulness of the 24 hour sub dial as I usually know whether it's day or night, but it does balance the main dial out nicely.Now the slide rule function, i.e. the two scales on the outer circumference of the dial is really superfluous today, although many chronographs do have them. You can do calculations by rotating the outer bezel of the slide rule using the button/wheel on the case at the 8 hour marker. I find it funny that the instruction manual doesn't even mention the slide rule I used one back in the late 60's in engineering school (they were straight like regular rulers rather than circular like on a watch), and back then the "bigger your stick" the cooler you were (there were nerds in the 60's too). Pilots used watches with slide rules to do flight-related calculations before there were tablets, calculators, and flight computers etc. Since there's really no good reason to use one now, I guess it's there because hey, it looks cool, and if you want to find out how it works, you can look it up on line!It's a really great looking watch with a lot of excellent features that you can set and then won't have to mess with at all in order have the time, day, and date kept accurately for years to come. One bit of warning, the pictures of the watch show detail on the dial that's much harder to see on the actual watch so you might consider passing this watch up if you have any difficulty reading very small print, otherwise I don't believe you'd regret buying one, especially for the price on Amazon that I paid for it. I only buy from authorized dealers and I couldn't beat this price with anything I found online elsewhere. If you buy it from an authorized dealer (there's a list on the Citizen web site), not only do you get a 5 year warranty, they'll also give you another year if you register the watch with them. Enjoy!
