What people say

Owners + reviewers, side by side

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

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.

Seiko Astron

The Seiko Astron is widely praised for its advanced time-telling technology, including GPS and radio wave synchronization, and its self-sufficient solar-powered quartz movement. Owners appreciate the detailed and high-contrast dials, comfortable and lightweight titanium builds, and well-finished cases and bracelets. Some users report excellent accuracy, with one noting +/- 15 seconds per month, while another finds the autonomous movement's accuracy of 1/2 second per day acceptable due to easy correction via GPS sync. However, the Seiko Astron's price point is frequently cited as a drawback, with some finding it high for a quartz watch, particularly when compared to luxury or mechanical alternatives. Specific criticisms include manual DST implementation, the need for outdoor sync, sparse lume, and a minute hand that sits slightly off on one model, with accuracy of +13 sec/month being disappointing for its cost on another.
