What people say

Owners + reviewers, side by side

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

Farer WORLD TIMER

Owners widely praise the Farer WORLD TIMER for its detailed dial work, including bronze inlay patina and shiny minute markers, as well as its powerful lume and gorgeous case finishing. The 39mm sizing is considered perfect by some reviewers, offering a blend of function and elegance that punches above its price point, while others find the matching blue dial hinders legibility. One owner noted the bracelet lacked microadjusts. Overall, owners and reviewers rate the Farer WORLD TIMER highly for its detailed dial work and versatile case finishing at its price.

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.
