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 Prospex Sea Save the Ocean Special Edition

The Seiko Prospex Sea Save the Ocean Special Edition is widely praised for its visually striking and unique dial designs, often described as a standout feature offering significant aesthetic appeal for the price. Owners and reviewers consistently highlight the attractive blue gradients, wave patterns, and textured finishes that evoke ocean depths. The watch is generally considered comfortable to wear, with a well-proportioned case size and good build quality. Accuracy is reported as around +5 seconds per day by one owner. However, several sources point to the bracelet and clasp as a weak point, with criticisms including pin-and-collar construction, stamped clasps, and a lack of a convenient diver's extension. Some reviewers also note potential issues with bezel alignment and day/date wheel alignment. On balance, owners and reviewers rate the Seiko Prospex Sea Save the Ocean Special Edition highly for its exceptional dial design and overall value.
