Axiom is rated 4.5 out of 5 by 24.
Rated 5 out of 5 by from Amazing watch I bought my watch over the friends and family event in Macys , and after a long time looking and comparing I settled on my citizen black chronograph echo drive, the amazing design just got my eyes and the reasonable price as well compacting to the other Movado that I was comparing this watch with , on top of that no battery change hassle , also 6 years worth of warranty fo this sleek watch . I loved it and had many good comments on it .

Rated 1 out of 5 by from 5 yr watch only My wife bought me a Citizen Eco-Drive about 6 years ago. It was an excellent watch until the battery quit working a couple months ago. The Citizen repair center tells me that the watch has to be re-certified and cleaned along with a new battery. The total cost to replace the battery is $259!!! I wish I would have been told this information prior to purchasing the watch. I am hopeful a representative of Citizens contacts me to correct this issue.

Rated 5 out of 5 by from LOVE this Watch! My fiancé got this for me for Christmas. I love everything about it. The sleek modern design is gorgeous. The weight is on point. Gives me a little extra pep when I wear it. I have received so many compliments on it! Love the fact that I will never have to replace a battery again! Great work Citizen. You crushed this one!

Rated 4 out of 5 by from Not the best Chronograph but oh what a looker. As with most of the Axiom line, this watch seems to take it's inspiration from the original museum watch by artist George Nathan Horwitt that has become one of the most visually distinctive watches on the market today. The watch is an exercise in simple elegance. This watch feels equally at home, in the office, or at an exclusive restaurant. It is the Horological version to the "little black dress" About the only places you need to avoid are the water and construction sites due to it's 30m water resistance and mineral glass crystal. And one might expect to find a sapphire crystal at this price point, but alas it's not to be found. As great as this watch is, if you really need a chronograph, look at another style. The photos show the markings being much more prominent than they are. The outer minute markers and markings on the sub-dials are only visible under the right conditions at the right angle. If they were as legible as they are in the photos, it would be great. It's the one major flaw I find in this watch. But then again, this watch watch clearly emphasizes form over function, and oh what an appealing form it has.

Rated 5 out of 5 by from Great watch I bought this watch 2 month ago. It's a very beautiful watch with excellent quality. Especialy for better locations i use it. Just one disadvantage. Sometimes it's a bit difficult to read the time because of darkness and the smal pointer

Rated 5 out of 5 by from Stunning yet understated This watch was a gift from my parents and I have to say I was pleasantly surprised by it. It is comfortable to wear and easy to read. It is my first Citizen and I'm sure will not be my last.

Rated 1 out of 5 by from Axiom Watch The second hand on the watch does not move. It arrived 2 days ago. I’ve left it where sunlight can charge the watch but it still doesn’t work.

Rated 4 out of 5 by from looks fantastic My girlfriend and i went into a Swiss Store and i was there admiring this watch. so she bought it for me. Wow! i wanted one of these for a while now. When I checked My e-bay i realized it was the very same watch i had in my watch list. how coincidental. i went for the silver with black dial.
