I have only had the watch for 10 days so I cant speak to long term reliability but it is accurate. It looses about 6 sec a day while wearing but at night sitting face up on the nightstand it stays within 1 sec. The band is very comfortable and has a quick adjust clasp but if you need more than 3/4" you will have to remove links. There are 7 removable links and are a bit tricky to get off as there are no instructions or paperwork included with the watch, however you can get directions from the web. My watch is a Made in Japan vs Malaysia sold by the local stores but I believe it is grey market which is why there was no warranty or instructions included and it was only wrapped around a Seiko pillow in a Seiko box but without the case or stand and flopped around in the box. You also only get a 2 year Amazon Warranty vs the Seiko 3 year Warranty. You cannot hack the watch (stop the second hand to sync) but if you really need too the second accuracy you need a quartz movement anyway not mechanical. The spring reserve is about 27 hours although it is difficult to tell if the watch is really completely wound with an automatic but count on having to reset it if you have not worn it all weekend and pick it up on Monday morn.  I really like the look and size of the watch. It is not a big watch, more reminiscent of the vintage watches of the 60's and your sleeve will drop over the watch without shaking you arm and your jacket does not hang up every time you need to look at it.
I would buy this watch again or recommend it to a friend and only held back on the 5th star because you do loose 1 year of warranty and there is NO paperwork with the watch.
