The Citizen Story

The company was established in 1918. The founding fathers selected the name Citizen so it would be "Close to their Hearts of People Everywhere" and soon after adopted the company's formal name, Citizen Watch Company.

During the last 93 years, Citizen has expanded its business throughout the world and has achieved recognition as a global brand. The past 30 year period has coincided with the company's dramatic rise to its current position as the world's largest watchmaker, a distinction Citizen has held every year since 1986.

Beyond sheer size, Citizen is also recognized as a worldwide leader in advanced technology. From the world's slimmest LCD watch to the first voice recognition watch and the world's first professional dive watch with an electric depth sensor, Citizen's record of "world's first" is unmatched.

With models ranging from dress to sport to professional dive watches, Citizen Eco-Drive runs continuously on any kind of natural or artificial light for a lifetime of use. Fueled by light, it never needs a battery. In 2007, Citizen introduced radio-controlled atomic-timekeeping to the Eco-Drive collection, thus developing the most accurate watches in the world.

With the presentation of Eco-Drive Satellite Wave at Baselworld in 2011, Citizen has re-affirmed its position as a worldwide leader in timekeeping technology.

    Finally, this watch looks great and is very easy to read.
    (Be aware that if you are in a region without Time Signal reception, the Perpetual Calendar feature needs to be manually set.

    One of my favorite watches is a Citizen Eco-Drive Skyhawk.

    I bought this Watch at Mississauga, Ontario, Canada for CDN$368 plus 13% tax. I noticed this on sale at another store for the lesser amount of CDN$338.00 - unfortunately only after I had made my purchase.

    UPDATES: Please see updates towards the end of the review.

    - Keeps highly accurate time to the seconds. I have compared it with computers that are freshly synchronized with time servers using NTP (Network Time Protocol) and it was found to keep exact time. I also compared it with CBC Radio time signal transmitted at 1:00pm. It was just amazing how the seconds hand points exactly at 12 O' clock position when the beginning of the long beep is heard from the radio. This accuracy, of course, depends on being in one of the 5 regions where it can receive a Time Calibration Signal.

    - Synchronizes automatically with Atomic Time almost every night (I noticed it missed one night with a snowstorm) at Burlington, Ontario. Attempts to manually synchronize during the DAY never worked. Attempts at manual synchronization at NIGHT worked fine most of the time. Burlington, ON receives the time signal from the NIST transmitter at Fort Collins, Colorado, USA. The Distance from Burlington,ON to Fort Collins,CO is 2109 kilometers or 1311 miles or 1139 nautical miles according to [....].

    - Perpetual Calendar feature is quite useful. For anyone unfamiliar with this feature: This feature helps show the correct date through out the year. It knows which months have 31 days, whether February will have 28 days or 29 days etc. Most watches will need their date to be adjusted manually a few times per year -- typically when the date transitions from a month with 30 days to the next or from February to March.

    37 of 38 people found the following review helpful By James E. Mcguire on November 11, 2010
    I bought this watch a few days ago at an authorized dealer at 40% off the suggested retail price of $650.00. The band and case is titanium which enhances the feel on your wrist. I own an Omega SeaMaster (James Bond version) which weighs five times as much as this titanium lightweight, and its price is ten times the amount paid for this watch. The quality of the Citizen is outstanding, and over time will prove much more reliable than the Omega.

    The cell is powered by natural and artificial light and contains a six month reserve. Thus, if the watch were left in total darkness, it would still run for a long time. The cell has a life time guarantee and the watch comes with a five year Citizen warranty.

    The stationary bezel of the watch displays the major cities in all 24 time zones. It takes only a few seconds to set the watch while traveling around the world. Additionally, the accuracy of the watch is paramount as it is an atomic watch with automatic daily adjustments syncronized with atomic clocks located in the United States, Europe and Japan. As the name implies, the date feature is perpetual. Thus, I will never, ever have to set the date or time on this watch. The only adjustment will occur when I change time zones.

    However, even given the beauty, craftsmanship and accuracy of this timepiece, the most oustanding feature, as far as value is concerned, is that the watch comes with a sapphire crystal. This renders the timepiece almost scratchproof. This watch has the look, accuracy and quality materials of watches costing much, much more. I challenge anyone to find a titanium watch with a sapphire crystal and all of the above features with a five year warranty at anywhere near the suggested retail price of $650.00.

    I purchased this watch BRAND NEW through an authorized dealer on Ebay for $263 with free shipping (wholesale price). About half off the regular retail price. I took it out of the box, and it was already the correct time for Santiago, so a few turns of the crown and it was at PST (Los Angles on the bezel).

    I love the clean look of the watch over the Skyhawk and Skyhawk AT, both of which are also perpetual atomic synced watches. The carbon fiber print and slight irridesence on the face make for an extremely modern and sophistcated look. The bezel seems small compared to a diving style watch, and it does not rotate, which all my previous watched had. The bracelet is high quality although made in China. it squeaks a bit off your wrist, but you would have to ask the question: "Why aren't you wearing it 24/7?" It locks down tight and it's not coming off your wrist any time soon. Three half links allow for precise sizing.

    I don't know why you would even not want to wear it. I wear it to get groceries, I wear it kayaking, I wear it swimming, I wear it hiking, I wear it at fancy retraunts. It's perfect for everything.

    The weight is similar to a Rolex Submariner or Omega Seamaster, and if you are used to those types of watches, you won't even remember you're wearing it. Not even close to the brick of a Rolex Seadweller I was wearing before this one. No, this can't boast that it functions at 12,400ft underwater, but neither can you. 200M of resistance is PLENTY for even small SCUBA dives.

    The lume is quite bright especially after being exposed to bright daylight (hard to find here in the Seattle area) And my only complaint about it is that the second hand doesn't light up so you can say it is exactly 12:01 AM and 6 seconds in complete darkness.
