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 Diamond Collection

Owners widely praise the Seiko Diamond Collection for its stunning beauty, particularly highlighting the 14 diamonds and the captivating mother-of-pearl dial. Its 33.2mm case size, 100m water resistance, sapphire crystal, and lightweight build are appreciated features contributing to comfortable wear. Some owners find the dial detail is best appreciated in direct sunlight. The gold plating on some models may show fading from desk work over time. Overall, owners rate the Seiko Diamond Collection highly for its dazzling aesthetics and comfortable, well-finished design at its price point.
