Description

Black dial. Silver-tone stainless steel case with a black canvas band. Automatic movement. 30 meters / 100 feet water resistance. Fixed bezel. Tang clasp. Case size 37 mm x 11 mm. Seiko SNK809 Seiko 5 Watch. The Seiko 5 Men's Automatic Black Strap Black Dial Watch is a stylish timepiece with the convenience of automatic movement. A uniquely designed, black dial features white Arabic numbers marking the hours on an inner circle and the minutes on an outer circle, while small, bar indexes encircle the dial on an outside minute track. Silver-tone hands with luminous fill make it easy to tell time day or night, and the slim second hand is detailed with a red accent. For added convenience, a day and date display are set at three o'clock. The polished stainless steel case extends to meet the black nylon strap, which wraps comfortably around the wrist and fastens with a traditional buckle. Water resistant to 30 feet (100 meters), this high-performance watch is perfect for everyday wear.This is an automatic mechanical watch. Automatic watches do not operate on batteries, instead, they are powered automatically by the movement of the wearer’s arm. If the main spring in your automatic watch is not wound sufficiently, timekeeping may become less accurate. In order to maintain accuracy, wear the watch for 8 hours or more per day, or manually wind the main spring by turning the crown. When not in use, automatic watches may be kept charged with an automatic watch winder – a watch storage unit which may be purchased separately.

  • Great watch, have 2, but face is hard to read!
I bought the black and blue versions of this fine watch. They serve as my day-to-day watch. As noted in other reviews, a self-winding watch is more accurate than a mechanical watch but far less accurate than a quartz watch. Quartz watches are off by about 2-3 seconds/month, compared to atomic clocks. Self-winding watches are off by about 7 minutes/month. I've found the difference to be negative not positive. Sieko says about 5 minutes/month. But, here's one advantage: you won't have to wind it, just wear it. That makes it the best watch available in the future ahead. It's getting harder to get my battery replaced on quartz watches and it will likely become impossible in future. It only takes about 39 hours for the battery to run down so it helps to rotate it (to wind) about 2-3 minutes a day. I can usually wind it in a commercial break. The drawbacks with the black model: * harder to keep clean; * the day and date diasl are harder to read because the face is black and so are the letters. All in all, it's a great watch. If this review was helpful, please add your vote. ____________________________________________________________ My review of the blue watch: Xbar 107 seconds/week (runs fast) (7 min./month compared to 2-4 sec./month quart watch) St DEV 27 sec. N = 7 95% CI 2.447 using Student's t m+ = 136 seconds/week m- = 78 seconds/week Summary: Good points: * Beautiful with dark blue face, white symbols, functional medium blue nylon band; * Easy to read, even in the dark; * Easy to use with uncomplicated settings similar to other watches; * Compact design; * Measurement consistency is excellent compared to quartz mechanism. Bad points: * Difficult to set time (see instruction below); * Gains 10 seconds a day (consistency); and * Does not have a manual wind stem. Discussion This watch looks great. Unlike other self-winding or kinetic watches, this one is compact. In the best tradition of Japanese product development they thought hard on how this watch should function and say about the wearer. The hands are easy to reading, even for those of use with failing eyesight. The second sweep hand has a red tip allowing easy setting of the time. Unlike some Japanese product, they provided a short, simple instruction on winding the watch. Here, I am comparing them to Citizen's ecco-drive watch, which I also own. Just gently work your arm back and forth for three minutes and the self-wind watch will charge; or, you could wear it for a day. Okay, now for the negatives. First, this is not your quartz watch. The original self-winding mechanism was invented, according to Wikipedia, by a Swiss watchmaker in 1770. Since then it has gone through several improvements but is not as accurate as the quartz mechanism popularized starting in the 1970's. Sieko warns that this watch could be off by as much as 10 seconds a day. One days use indicates that my watch runs about 10 seconds fast. The great watchmaker Harrison, who invented the first chronometer accurate enough to track longitude, said that consistency is more important than accuracy. (A poor copy of one of Harrison's chronometers was carried by Captain Cook on his circumnavigation of the globe. He had nothing but good things to say about it.) I have another self-winding watch, an Armitron, which runs consistently 15 seconds fast on days that I wear it. From my measurements of quartz watches, their accuracy, while dazzling when compared to old hand-wound watches, are less accurate than my old German pendulum clock. So I am told, the longer the arm, the more stable the swing and the more accurate the timepiece. I compare everything to atomic time. And, because the quartz mechanism is battery-driven, it seems to suffer from inconsistency. I carefully measured my collection of six quartz watches over a 2 year period. While the battery was new, the error was consistent. As the battery burned out, the error became difficult to predict. Sometimes a positive error (adding time) would become a negative error (losing time) as the battery died. This dying period was also hard to predict. The accuracy of the quartz mechanism is not as good as my pendulum clock. They all lost or gained approximately 2-3 seconds, on average, per month. Based on a week of measurements with the Armitron, I would say that it is shockingly inaccurate but consistently so. Assuming that the Sieko error continues to be consistently 10 seconds fast this will mean that I will have to reset it every week. This is a small price to pay for an otherwise beautifully crafted and honestly-priced handiwork. Setting time The date and day are fairly easy. I suggest turning the watch arms until the click past a day so you won't be twelve hours off. Setting the time is another matter. What works best is to set the hour and minute hands, then gently hold the second hand. It should pulse a little as it tries to force itself forward. Once the seconds are accurate, release and the second hand should be accurate. It takes a little practice at first and don't set the time until you pump the watch 3 minutes to charge the spring. Time to unwind It takes about 39 hours (1 test) to unwind. ... show more

  • Perfect for Men and Women! This watch is a winner!
I am new to automatic and mechanical wind wristwatches, so, after purchasing a rather expensive battery operated quartz movement over a year before this Seiko the battery went dead and that was a huge disappointment for me. The battery operated quarts movement watch that I owned was supposed to have a 5 year life but died much sooner. I took the watch to a jeweler to have the battery replaced and the cost for the replacement battery was through the roof. Not only was it expensive to have the battery replaced but the Jeweler ruined the water resistance 'integrity' of the watch by smashing the o-ring that seals the back of my watch. Well, it didn't take long for my battery operated watch to become totally destroyed by water intrusion. Almost immediately after my battery watch failed that's when I decided that I was no longer going to buy 'ANYMORE' battery operated wristwatches so, the search began for a new mechanical or automatic watch. It took a long while, I was shopping almost everyday for over a month but most of the wristwatches were overly expensive and had features I wasn't really excited about. After about 2 months of shopping I accidentally stumbled upon these Seiko's. I sure am glad I waited and found them. I AM VERY PLEASED! When I received my new Seiko automatic wristwatch I could see right of way it was no piece of junk. It was heavy and felt good in my hands. The dial was easy to read even without my eyeglasses. I am a 54 year old man with extremely poor vision so I need high contrast to see the time and daily calendar. Although some reviewers may have complained it's smaller then what they had expected, I think it's a very appropriate size for both males and females. Perhaps for some people and I guess depending on your taste in fashion and social statement perhaps it may be to small for some men. I am a 6 foot man at 260 pounds and I think it's a perfect size and I am very picky. Just so everyone knows, most of the watches I currently own are the Invicta Russian Divers and they're huge timepieces, I really love those large watches however, this smaller Seiko watch was refreshing. What I mean by refreshing: I am always worried about ruining my other expensive watches, I don't wear them everyday but this Seiko is a watch I can wear everyday and not worry about banging it around since they are cheap enough to actually purchase several others. These Seiko's are perfect for everyday wear. I usually only wear my Invicta's when I go to dinner or some other social gathering but these Seiko's are actually very pretty and masculine enough to go out for dinner or other social occasions. Really, it's not that small and it's also not an ugly watch. This Seiko wristwatch probably won't get noticed as much as perhaps another more expensive wristwatch but if you take it off and show it to someone I know they are going to like it. I think what matters most to myself is knowing that I have a brand new 'name brand' Seiko quality wristwatch and never have to worry about a battery ever again or accidentally breaking it. I'm usually pretty careful so I am not really worried about breaking it although, this Seiko feels really tough so I think it can take a good beating. Let me tell you what I like about my new Seiko wristwatch. First, It keeps perfect time. After just a few days it's still accurate...I like the size of this watch, large watches get bumped a quite a bit however this watch has a lower profile so it's not likely to easily bump into things as you perform your daily chores... I like the stem at the 4 O'clock position because it makes it much easier to adjust without having to remove the watch from my arm...The brushed steel finish is absolutely beautiful... The crystal is flat making the watch face easy to read at any angle... I truly like the high contrast of the hands against the dial... The calendar is very large and very easy to see with ample contrast even without my eyeglasses... Pulling the stem out one click sets the calendar without stopping the watch, turn the stem clockwise for the day and counter clockwise for the date... I like that the watch movement does not stop operating when the stem is pulled all the way out to adjust the time, you can however stop the watch from ticking if you put some slight counterclockwise pressure on the stem, this allows for more accurate time setting. A little more counterclockwise pressure also makes the watch run backwards for even more accurate time setting... I happen to like the watch band and buckle, too... What I really like are the luminescent hands and markers. I noticed just this morning after 5 hours of compete darkness the hands and markers were still view-able although, the luminescence wasn't overly bright but there was just enough to see the time in complete darkness... I like that the watch is not overly complicated with sub-dials. Everything I need to know about the time and date is supplied with this Seiko... I like that it's water resistant... Finally, I really like that's it's a Seiko but more importantly it's the perfect wristwatch with all the perfect features for the perfect price... This watch has all the features I was looking for in a in a new watch... I have to say, "I am so very happy with this new watch so I just purchased two more in different colors, the tan and the blue. Soon I will buy a green and another black. I think you'll truly enjoy this Seiko wristwatch! I am not disappointed whatsoever so, I highly recommend the purchase of this watch. For this kind of money, it's absolutely PERFECT! Thank you for reading :) . ... show more
