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

Owners widely praise the Seiko Prospex Sea for its excellent value, robust build, and superb lume, with many appreciating its comfortable wearability due to its case shape and lug-to-lug distance. Reviewers consistently highlight its impressive finishing and classic dive watch design, often noting the bright LumiBrite lume. Some owners find the watch to be large, thick, and heavy, while others consider it the perfect size, indicating a split opinion on wearability for smaller wrists. The power reserve from some movements is noted as less than newer variants, and the clasp quality receives mixed feedback. Overall, owners and reviewers rate the Seiko Prospex Sea highly for its exceptional finishing and value proposition in the dive watch market.
