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.

From video reviewers

The dial's recovered marine plastic construction with textured finish provides distinctive material differentiation at the entry-level dive watch price point, and the sapphire crystal with anti-reflective coating ensures strong on-wrist legibility. The 300m water resistance and automatic movement deliver capable specifications, though bracelet quality and fit remain underspecified across reviews.

Undone Basecamp Gmt

The Undone Basecamp Gmt is widely praised for its vintage military aesthetic, comfortable 40mm case, and excellent value under $300, with reviewers noting its smooth, precise bidirectional bezel. Owners and reviewers consistently flag the Lexan polycarbonate crystal as a concern for long-term scratch resistance. The watch uses a Seiko NH34 automatic movement, and while its water resistance is listed as 50 meters, it is reportedly tested to 100 meters. One forum user points out that the orange arrow hand indicates the 12-hour time, not the 24-hour GMT function. Overall, owners and reviewers rate the Undone Basecamp Gmt highly for its versatile vintage design and strong value proposition.
