  • Perfect
Very happy , great watch
Reviewed in the United States on August 11, 2025 by roger gaddis

  • 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. ... show more

  • Good watch?
This is a very nice watch, but it does have one drawback. Even with the bubble on the date window it is still very hard to read. I had to send the watch back.

  • I would buy again
Excellent!

  • Defective. New?
Received product and was defective out of the box. Had it on auto winder for 4 hours and watch never started. Also, when I opened the box it did not seem like it was packaged like a new watch, I think they sent me used/returned product. Returned the watch same day.

  • All the right vibes!
I have been aimlessly searching for a casual, weekend watch. This design flirted with me but spent a few weeks looking for something else. I decided to finally pull the lever and it was the right decision. I wear platinum jewelry but wanted something with two-tones that give me style flexibility. The longer you look at it the more attractive it becomes. Excellent quality and price point. Delivery and shipping was fast. Happy Birthday to me! ... show more
