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 design, with specific mentions of its beautiful ice blue sundial and compact 39mm case size, which some note wears smaller than its specifications due to a short lug-to-lug distance. Reviewers highlight its racing-inspired aesthetic and versatility, with one owner finding the 39mm solar model a sturdy and reliable everyday watch with 100m water resistance. However, some owners question the value proposition, citing the $700 price for a solar quartz model and a thickness of 13mm, while others expressed a preference for automatic movements. On balance, owners and reviewers appreciate the Seiko Prospex SPEEDTIMER's attractive vintage-inspired design and compact wearability, though some debate its value and thickness for a solar quartz chronograph.
