What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Grand Seiko SLGW004

The Grand Seiko SLGW004 is praised for its elegant, faithful reissue design and impressive technical execution, featuring a new 9SA4 hi-beat manual-winding movement with an 80-hour power reserve and accuracy of -3/+5 seconds per day. Reviewers highlight the sharp case facets, double-signed dial, and beautifully decorated movement visible through the display caseback, along with an enjoyable winding experience. One reviewer noted a desire for better water resistance and expressed a dislike for the etched sapphire case back. Overall, reviewers rate the Grand Seiko SLGW004 highly for its elegant design and technically impressive movement.

Spinnaker Hass Automatic

The Spinnaker Hass Automatic is a 43mm watch featuring an NH35 movement and sapphire crystal, with owners highlighting its beautiful dial. Some find Spinnaker watches, including this model, to be on the thicker side, with one owner describing the Hass X MCS Blue Fade variant as comically large and chunky. The Spinnaker Hass Automatic was offered at $445 USD as part of a special collection with customized elements, and a limited edition of 200 pieces was also available for $195 shipped. On balance, owners and reviewers note the attractive dial as a key positive, though some express reservations about the watch's thickness.
