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

Owners widely praise the Seiko Prospex Sea Save the Ocean Special Edition for its exceptional and captivating dial designs, often described as a highlight that evokes ocean surfaces with unique textures and color gradients. The watch is frequently noted for its excellent value, with some reviewers comparing its aesthetics to much higher-priced brands.

The Seiko Prospex Sea Save the Ocean Special Edition is available in various case sizes, with some owners questioning if certain dimensions are too bulky for daily wear.
