  • Have wanted a titanium+sapphire and now get eco-drive too! Perfect everyday watch
Color: Silver Bracelet, Blue Dial
As much as I like Stainless steel divers they are too heavy and scratch too easily for everyday use. The sapphire crystal on this watch plus the hardened titanium of it's case should hold up better as a beater. Couldn't resist the price of the blue face Paradigm $210 on Amazon compared to $380 everywhere else. Not having to replace battery will keep the water resistant seal good for a long while. Blue textured dial looks awesome and lume is good but tick below Seiko Lumi Brite. Only con is small date number window. ... show more

  • Great looking watch.
Color: Silver Bracelet, Blue Dial
Watch looks and feels great on the wrist. Lightweight compared to some of my other watches. Love the blue face and titanium band, very comfortable.

  • Great Looking Watch
Color: Silver Bracelet, Blue Dial
The watch arrived like new. The watch fits and looks great on my 7 3/4 inch wrist. The face is darker than pictured. It's more of a deep navy blue. The watches case and band are more of a light grey with a deep navy blue face.

  • Nice watch
Color: Silver Bracelet, Blue Dial
This is a nice watch--comfortable to wear and lightweight. However, either Amazon sent me the wrong color, or Citizen's version of blue is far different than mine. Basically, the face on the watch looks black. Disappointed in that, but otherwise satisfied.

  • Waterproof sapphire timepiece
Color: Silver Bracelet, Blue Dial
This is a nice watch with beautiful titanium bracelet and sapphire glass pieces. Also rated up to 100m water resistance which should be fine for most water activities However do note that crown is not screwed in but pop-in/out. Keep pretty accurate time and was able to retain charge even when placed for several days in the original bow. Sizing for the titanium band tend to run large with only 4-5 adjustable links....maybe a issue if you have small wrist. As it is titanium, watch is very light and easy to carry it around. Link are also pretty hardy and resistance to scratches so far. Color of watch face run deep blue rather than the brilliant blue but still look rather elegant. Watch is also rather large 43mm and hence ideal for those who prefer large watches. Overall a very nice waterproof timepiece that is hardy and sturdy and yet look elegant for all occasions. ... show more

  • Love it. I wear it 24/7.
Color: Silver Bracelet, Blue Dial
Love it. I wear it 24/7. I chose the Blue Dial. It's a very dark blue that only looks blue in direct daylight.

  • A Great Disappointment - Poor Quality
Color: Silver Bracelet, Blue Dial
This is a beautiful watch with a titanium case and sapphire crystal for less than $250, depending on the discount Amazon is offering at the time. That should be steal, unfortunately you usually get what you pay for. The overall design is elegant, simple and in good taste, perfect as an everyday watch that can also be worn in dressy situations. It also has Citizen's Eco-Drive movement which I know from personal experience is accurate and should last approx. 20 years without a battery change. Unfortunately, the overall quality may not be out of line for what I paid for it. (1) The hands don't line up with the markers on the dial, in fact they were almost exactly in the middle of the space between the marks. I believe this is fixable, but a buyer shouldn't have to deal with that. (2) The bracelet is poorly designed and of bad quality. The gaps between the segments are too large, especially if one has a narrow wrist which causes the gap between the first and second segments to be especially large. The bracelet just feels loose. Other reviewers have complained of pins dropping out and the clasp being of poor quality. I'll add that the titanium is discolored in the visible gaps between segments. (3) This is a big watch - 41.5 mm diameter measured diagonally, and 43 mm measured horizontally across the crown. That shouldn't necessarily be a problem - this watch is smaller than most G-Shocks, including my own, but the bracelet is huge and may not be sizeable down enough to accommodate smaller wrists like my 6.5" wrist. For these reasons I returned it. I am a fan of Citizen products and love their Eco-Drive. In fact, I don't wear mechanical watches anymore. Too much bother. I have no idea what Citizen was thinking when they designed the Paradigm. ... show more
