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.

Tissot Seastar 1000 Powermatic 80 GMT

Owners widely praise the Tissot Seastar 1000 Powermatic 80 GMT for its excellent build quality, smooth winding feel, and the reliable Powermatic 80 movement providing an 80-hour power reserve. Reviewers highlight its remarkable value under $700, comfortable wearability, and appealing case/dial ratio. Some owners note the bezel's functionality for tracking a second time zone and the need to adjust the hour hand for date setting, a characteristic of its "True" GMT function. The rubber strap is considered comparable to those found on significantly more expensive watches. However, concerns exist regarding the movement's serviceability due to potential plastic components and reliance on Swatch Group service centers. Some find the bezel font and dial spacing unappealing, while others question the mineral glass bezel insert as a cost-cutting measure compared to ceramic. Accuracy is generally reported as good, though not COSC certified, and lume intensity is described as average by one owner.
