I bought this watch for several reasons. R rm'agradava style, modern and classical elements. R twice item caught my attention, beautiful and also a great classic look. R-core has the right .... show me the time and show me the date (in a readable size for the eyes of my 45 years old!). R-settlement does not require, use, or batteries due to Eco-Drive technology. R rthe watch was posted (or at least meet the Amazon and it arrived in perfect condition with all boxes and manuals. R rmy impressions are very positive. R rPros: r r perpetual adjustment date. Sets the number of years since the handover, month and day of the month and the details are correct perpetually for something like the next 100 years. r-style Once again, the perfect combination of classical and modern elements. but I really like the image displayed on Amazon. It should be noted that the face is actually a very dark blue, so dark I 'm not sure you even have noticed until I was 17 years write about the color. r-about the right size. r-marked face and make you glow in the dark markers ... Don 't think it ' ll use a lot, but a nice touch anyway . r-Eco-Drive ... no batteries and seems to work well out of the box. r rcon: r r-can be DESET on an island for 10 years with this clock, and not be able to find a way to set the date without the instructions. L 'printed instructions are confusing and Don ' t really seem to be quite accurate. On the positive side, watch ships with a mini-disc that provides a walk reasonably fast, though. A wise .... Don 't need to waste as the new disk when the power runs out the clock! r r-The clock is a little thicker than you prefer. Only a Personal preference, some people like a large clock and thick, I 'd prefer to ~ 20% thinner. The thickness is probably due to all the technology in the toy box (Eco-Drive, etc. ... .) r r-Don 't love to see the band, seems designed to be high, but I ' d prefer a single buckle strap. There are also instructions on how to adjust the time, I ' m sure that 's an easy process, but wants to break a new purchase yanking closures? r r-last with a little more neurotic (but at least I know!). The date of two screens (one for each digit) are fixed in a slightly different background on the clock (I 'm sure the internal mechanism), as a result, the display of the digits is compensated, it has something more shade and a little less bright because it is receiving less light and drowned. r Rall in all, I love the watch and no doubt buy again! r r [... ]

I did a bit or research before buying this watch and am very happy with it so far. The watch looks great, has a band of high-quality leather, and has drawn many compliments so far.

Muito bom o acabamento, EU goistei, quem for the Procura relógio sobrio esta e uma opção python.

This is my second Citzen watch, and my second Eco-Drive. I have a modest collection of watches at all prices, technologies and styles. Included are battery powered quartz models, mechanical automatic (European), and two Seiko Kinetics. I love them all, and all have a place for different uses in my life. R rin my opinion, the search for minimal maintenance, high quality, reliable and accurate time pieces is fulfilled in all aspects of the Citizen Eco-Drive line of watches. R rthe new Eco-Drive Caliber 3100 Perpetual Calendar series Relief is one of the classiest designs to come out in years. Once set to the next leap year, year, month and date, and after an initial period of appropriate pricing, it 's ready to continue indefinitely, without adjustments or power issues. As another reviewer said, it 's true "Grab and Go " chunk of time. R rasid superb technical features, already described, here are some things I love about this version of the Caliber 3000: r rthe all stainless steel case is solid and well done. The project if you have a bit of a retro-looking, Remiscent watch classics from years gone by with gentle curves, a simple and uncomplicated style with the side intensified Subltle surrounding the whole affair. R rthe is a combination of markup beautiful classic style, with a subtle use of classic modern numerals Romal combined with strong accent. R rthe bold and staggering separate numeric data using rotating disks that serve a dual task: first they are cleverly used for the initial configuration of the perpetual calendar and second as a simple but elegant looking surprisingly bold and date display. Once the initial setup has been completed, the date is always correct, always, without the need to adjust it ever again, ever. While the cell's energy reserve is kept charged by the invisible photo-voltaic solar cells, is the situation sa 'forever. While there is light, any light, it never fails. R rback the project. The face is a combination of multiple landscapes that give a characteristic feature of modern design classic case. Precisely designed and placed markers are so visible as to make counting time "at a glance " an easy process. The second 's sub-dial at the bottom of the eye is highly visible, with class to look at, while not observing Interfaith with hours and minutes. There 'sa 24-hour discrete sub-dial at the Nine ' clock position that quietly but effectively differentiate between AM and hours, hours to maintain. R rthe leather strap high quality, equipped with a "Crocodile " design, is sturdy, padded, and yet light enough to be extremely comfortable.This watch has a button deployment CLASP incorporated into the band for greater security and safey. The final addition very thoughtful and high quality for this high average price of the watch. As a unique feature, the band is custom made to extend past the LUGs to provide a snug fit against the case almost seamless curvas.Novamente, a feature usually seen in much more expensive, high-end products. I have great wrist, and still watch it fits me like a glove straight out of the box. Was immediately comfortable. There is plenty of room to scale it down if necessary to the pulse of small businesses. R thing daydream about this watch exudes quality. I am very fond of several watches in my collection. This can only zoom to the top of the list. Citizen has very good taste, and thoughfully achieve a style that will look appropriate in almost any situation, sport casual, or dress. Well done and supported by the Citizen 's reputation for quality, reliability and longevity, this is one of the most innovative and comprehensive Coolest parts to beat the market average price in many years. I 've only had it a few days, and I already love it. R ramazon had for me a week earlier than promised, and shipping was free. Combine that with the discount price, it 's one of the best purchases I ' ve done in a very long time. R rif that you're thinking of buying a Citizen Eco-Drive Caliber 3100, I think no more. Today this model, in all versions, is an innovative masterpiece. Over time it will become a classic of world renown. R rEnough 's superlative. By now you've probably deduced that I am very happy to have this watch in my collection. My biggest problem will be to try to set it aside from time to time to enjoy wearing the other watches in my collection. R rCitizen Rock and Eco-Drive - perhaps even "rules " .. ..
