Review: Perfect - Very happy , great watch
Review: Another brilliant watch from Seiko - This watch is widely admired and widely reviewed. I have little to add, except that the compass feature is very cool. Google it and you will learn how to use it (although it is cloudy and rainy today, so pointing the hour hand at the sun would not be easy). This watch is exemplifies why Seiko is hands-down, the most innovative and admired watch company in the world. Not the only good watch company by a long shot, but from excellent $200 watches to mid-range watches like this and its legendary divers, to collectible Grand Seikos, the company never ceases to amaze.
