Now to the actual topic, the clock:
The clock is a Seiko Sports 5 SNZF17K1 model, ie the model that is not manufactured in Japan (this would be the model SNZF17J1 and costs more and is hard to come by). If you are not a watch collector, this is not important because the quality of the watches is the same. The clock is a clock with automatic self-winding. It is 100 meters water resistant, which is sufficient for normal daily use. For diving I would to a higher model grab with about 200m depth or more. Since most people carry these watches but simply because they are reliable and beautiful to wear, and do not operate so as scuba diving, the water resistance is perfectly fine in this price range.
The clock is made very beautiful and everything fits like a glove. As described by others, the clock has a very good size. Not too big and not too small. In the picture the seller the clock ehr looks blue, but what it is not. The bezel and dial are black. To get a better idea, you should before buying a few pictures on the net look (as I've done it). The cover on the back is transparent and you can see the automatic movement. The band is also made very beautiful, nothing wobbles and everything is in its place as it should be. The safety clasp is also well finished and is easy to open and close. The cut of the band was very easy with the right tools and lasted only a few minutes. But the fine tuning is a little fiddly job and not as nice as for example in a Rolex Submariner (but we do not want to here a Mercedes with NEM Lamborghini compare), we are in the price range up to 300, and not until 4800. But if everything is easily adjusted sits the clock like a glove and is always a Hinguker. The date display shows the day of the week in English and another language I am not powerful, I think Chinese or Japanese), and day of the month as a number.
As for the power reserve and the path difference, I can not have much to say, since I do not yet possess the clock long. The clock loses time in 7 days approximately 25 sec. The heist readjust every 2 weeks is sufficient. The clock is very accurate and for the price definitely a bargain. The power reserve, I'd have to try out yet, as far as I can tell there are more like 36 hours.
Now the last and most important point:
Price and warranty. The price was when I bought it 190 including 5 shipping fee. Guarantee you about Discount Store and is 1 year. The guarantee document is in the package at with.
All in all a very nice and high quality clock for an unbeatable price. Definitely a buy recommendation.
