What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Hamilton Jazzmaster Open Heart Auto

The Hamilton Jazzmaster Open Heart Auto is noted for its dressy yet versatile design, featuring striking gradient dials and intricately shaped cutouts that reveal the H-10 movement. It boasts an 80-hour power reserve and Nivachron hairspring. The watch is available in 36mm, 40mm, or 42mm stainless steel cases. On balance, the Hamilton Jazzmaster Open Heart Auto is appreciated for its visually engaging dial and movement display at its price point.

From video reviewers

The smoked dial's precision cutouts offer a captivating view of the automatic movement. Legibility is compromised by the open-heart design.

Spinnaker Hull California (Popeye Navy)

The Spinnaker Hull California (Popeye Navy) is noted for its unique design, featuring Popeye's arms as hands, which appeals to owners seeking a bold, quirky piece. Some owners appreciate the watch's solid build, textured dial, applied indices, and applied logo, along with decent SuperLuminova lume on the hands and indices. The watch utilizes a Seiko NH35 movement with a power reserve around 40-41 hours. One owner points out an anatomical inaccuracy in the Popeye depiction, with both characters shown with two right arms. Another reviewer notes the 42mm cushion case has a noticeable 15.7mm thickness.
