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 PADI Special Edition

The Seiko Prospex Sea PADI Special Edition is widely praised for its attractive blue and red PADI colors, rich dial aesthetic, and excellent lume that stands out even in dim environments. Owners highlight its robust build quality and excellent bezel action, noting the wave dial is a favorite. However, the Hardlex crystal and the 4R36 movement's accuracy range of +45 to -35 seconds per day are identified as compromises for the price. Some owners find the diver's extension difficult to open and the bracelet adjustment challenging, though manageable. On balance, owners and reviewers rate the Seiko Prospex Sea PADI Special Edition highly for its build quality and striking dial design at its price point.
