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 SPEEDTIMER

Owners widely praise the Seiko Prospex SPEEDTIMER's gorgeous, unique red dial and vintage-inspired design, finding it a sturdy and reliable everyday watch. Some owners, however, question the value proposition at around $700 for a solar quartz model, citing its 13-15mm thickness and the 24-hour subdial as drawbacks. Accuracy figures vary, with one owner reporting +1/+2 seconds per day, while another notes the V192 solar movement offers a six-month power reserve. Overall, owners and reviewers find the Seiko Prospex SPEEDTIMER a capable and versatile chronograph, with its striking dial and everyday wearability being the most frequently cited strengths.

From video reviewers

The Seiko Prospex SPEEDTIMER's solar movement provides reliable power without battery replacements and accurate timekeeping, with a claimed accuracy of ±15 seconds per month. A notable trade-off is the watch's slightly thicker profile and somewhat lacking lume brightness. Reviewers disagree on whether the bezel action is smooth and clicky, with one reviewer praising it and the other not mentioning it.
