1. Dial face is not as blue as pictured.
This is correct. Whomever photoshopped that pic to be a lighter blue did not do themselves (or anyone else) selling or buying this watch any favors. If you go to Citizens own website and look up this model, their photo is a much better representation of the dial color. Although I would appreciate having the brighter blue face, it's a deep blue that actually looks great but certainly doesn't pop as much as the photo would show. The waffle pattern of the solar gathering face adds a nice contrast and pattern to the surrounding indicators. My hunch is that since this recharges via solar light there is a simple explanation for the deeper color, dark colors absorb light and lighter colors reflect them (along with the associated heat), so I would guess that most of the Citizen EcoDrive watches have darker faces to absorb as much of the available light as possible for just this reason, although I have not researched this beyond posting it. I don't believe this watch was ever made in the lighter color shown, at least not that I could find.
2. The watch is heavy for being titanium.
Non-sense. This watch is feather light on the wrist, you can barely tell it's there, especially for having a metal band (which is also titanium). There were also comments about the titanium and its finish scratching easily, although I haven't had it long enough to verify, I haven't seen anything so far to indicate it will do so anymore or less than other metal watches.
3. The anti reflective sapphire crystal has a lot of glare.
Partially true. I don't know what anti glare treatment has been done here, but it doesn't have anymore, or less, glare than other sapphire or mineral crystals I've worn. It's very clear and won't scratch, if you haven't already, don't ever buy another watch without a sapphire crystal unless it's for junk/throw away, they are far more durable than mineral or the like and hold up well.
4. The date window is too small and hard to read.
I suppose this depends on the persons eye sight but I'm going to say non-sense, it's not large by any stretch but if you can't read this you will likely have problems with most other watch date windows as well. I think part of the problem here is that the window is on the smaller side of average and the number sits a little deeper than some which probably contributes to shadowing depending on the angle of view and how you're looking a it. Works plenty fine for me and I've got average eye sight.
5. The band is proprietary to Citizen and can't be replaced after ten years.
Although this is likely true it's a bit of a red herring to look out ten years and try to forecast if the watch band will be broken and wether Citizen will be able to repair it or not in that eventuality. This is not a thousand plus dollar watch and although I'd love for it to still be working 20 years from now, worrying about such a thing for a sub $200 watch is a waste of your valuable time.
6. The second hands don't line up with the dial indicators.
Non-sense. The reviewer who stated that either has a defective watch or isn't compensating for the different angles the hands are viewed at while it sweeps the face, this is a non-issue, lined up nicely, obviously if it's not on yours return it or have Citizen repair under warranty.
7. The indicators and dials don't glow very brightly or for very long.
Non-sense. It glows blue after being exposed to light, but remember blue is not as bright to the human eye as green so it will appear slightly softer if not dimmer. I held it up to a 40 watt LED bulb on my night stand for a minute, set it on the dresser and then went to bed, 7 hours later I woke up while it was still dark and could see it glowing clearly 10 ft away, albeit a dimmer than I had left it the night prior.
Bottom line, this is an excellent watch that has all the desirable features; EcoDrive charging (no batteries needed), Titanium case and band (super light), sapphire crystal (will not scratch), water resistant (for all but scuba diving), uncluttered face with only a date window. Watch case is 43 mm's wide (47 including crown) as measured with a digital caliper and weighs 97 g's with 3 of the links removed for fitting, sorry, didn't weigh it before adjusting the band. I got this on a Gold box deal for $160 and it's an absolute steal at that price, if you can get this thing for anywhere close to $200 (which shouldn't be too difficult) it's well worth it.
1) The watch is hardened titanium- Some people want a watch of this type to be heavy and substantial and don't want a watch with hollow links. As for me, I don't want a 2 pound watch on my wrist, so titanium is a good choice. I'd say it reduces overall weight by about 30-40% over traditional stainless steel. Titanium is incredibly strong, but soft...so citizen hardens it with an exterior treatment. How scuff resistant is it compared to stainless steel? only time will tell. I emailed citizen who never fully answered the question. Views from watch forums suggest it's slightly less scuff resistant than steel. If you're hard on your watches and hate scratches, you may want to reconsider. Also, because the hardening is a coating, you cannot buff scratches out of the finish. It's definitely a trade off. That being said, the lightness is a definite plus for me.
2) The watch has a sapphire crystal - Many of the more affordable citizen watches don't. they use mineral crystal instead which is more shatter-proof, but less scuff proof. I have never shattered a crystal, but I have gotten plenty of scuffs on them, so sapphire crystal is a great feature. It is the hardest, most resistant crystal a watch can have.
3) This watch has solar eco-drive - While this watch will never need regular battery replacements, it does have a battery where the watch stores the energy from the solar panel underneath the dial. Fortunately, it should last the life of the watch. According to the manual, It takes about 11 hours in daylight to completely charge the watch. After that, it can run in total darkness for up to 6 months. It can collect enough energy in 2-3 minutes of daylight to run for an entire day. It will also charge from artificial light, but more slowly. No need to worry about finding the right battery, or violating the integrity of the case by needing to open it up every couple of years. I know eco-drive owners who have had their watches 10+ years without needing them serviced. Let's hope that is my story.
Other observations: The face is a dark blue, like a navy. Some photos show it more of a royal color, some (like this one) show it closer to black. It really depends on the lighting you're under. In the dim light of my office, it looks black. Outside on a bright, cloudy day...it's more like navy. Still, it's attractive and very easy to read. My second hand aligns perfectly with the dial marks..although i've read some do not. The date windows is very small, too small for a watch of this size. Unless you have great eyes, it will be a strain to read.
The hands and hour markers are luminescent and glow with a light blue color. This glow is strong at first but quickly fades, as luminescent paint tends to do. Still, it's better lume than many watches I've had.
The band is comfortable and you will need to take it to a jeweler to be resized. Please be aware that citizen does not have half-links available...BUT...if you look on the clasp you'll see 2 sets of adjustment holes. The band can be moved in about a half link's worth...making a more customized fit possible.
I've only had the watch a couple of days but it keeps excellent time and I expect it will be well within the +/-15 seconds per month range of most quartz watches.
so what DON'T i like?
I wish the clasp on the bracelet had a secondary flip-down security lock. Some do, this one does not. The date window is needlessly small. It would be easier to see if it were larger...at least with my 40 something eyes. I do wish the watch had a screw-down crown to help keep water out. It doesn't...but then this watch really isn't a diving watch. Lastly, even though the sapphire crystal is anti-reflective, there is a fair amount of space between the dial and the crystal, so you can and do get some reflections/glare at certain angles.
I really like this watch and I'm hopeful it will serve me well for years to come. I consider this to be a very good watch for the price with a great combination of desirable features. It's dressy enough to be worn with a sportscoat, but casual enough for everyday wear. I like that it's in-between a dress watch and a diver style watch. I feel I made a good choice and will try to update this post as time passes....

A note on resizing the bracelet, when tapping out the pins from the links be super careful because there are small conical collars/grommets in each link that stops the pins falling out of the bracelet. this isn’t a new design but I wasn’t familiar with it and had to hunt for the tiny pieces of metal on and around my desk after I lost them, I did find them in the end and all was well.
I've owned a citizen eco-drive titanium watch for 9 years. a BM1290. Its been worn daily, and occasionally even worn for sports. This is still a great watch, and has only sustained a minor and acceptable level of scratches on the bracelet and body. The sapphire glass has resisted many accidents and remains unscratched. The solar mechanism has always worked perfectly, never losing charge, and always with perfect time keeping. I purchased the new watch on a whim to ensure that I have a replacement for the day that the older one eventually breaks through accident or battery failure.
A note of caution - unless you have huge wrists you will need to remove some links from the bracelet and this is a very fiddly job. There are various videos on YouTube but I could not find one for this model. It has a pin secured by a minute scroll pin (easy to lose) situated in the middle part of the link. Difficult to do single handed and really best with a magnifying glass. Good luck.
Unfortunately i had to send back to amazon after talking to customer services as they could not resolve the issue and advised to return the watch.
I would have liked a replacement but because i purchased on warehouse deals this was not an option, shame i did like it.
