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.

Vaer G5 Meridian GMT

The Vaer G5 Meridian GMT is a compelling and affordable true GMT watch, featuring the Miyota 9075 movement. Reviewers note its 39mm stainless steel case, which is described as chunky but visually minimized by twisted lugs, and a highly domed sapphire crystal that contributes to reflections. The glossy ceramic bezel also adds to its shiny appearance. On balance, owners and reviewers rate the Vaer G5 Meridian GMT highly for its true GMT functionality and value.
