What people say

Owners + reviewers, side by side

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

Bremont Terra Nova 38

The Bremont Terra Nova 38 is widely praised for its unique geometric cushion case, featuring a combination of finishes, and its crisp, legible dial with luminous numerals and a gold seconds hand. Owners appreciate the quick-release bracelet. However, the movement's 38-hour power reserve and plain caseback engraving are considered uninspired for the price by some. One reviewer would have preferred a screw-down crown and caseback for a rugged field watch, and the bracelet lacks micro-adjustment. The Turquoise Limited Edition variant was criticized for its $3,450 price and legibility issues with white numerals on the turquoise dial, though the dial and lume were appreciated by some. On balance, owners and reviewers value the Bremont Terra Nova 38 for its distinctive case design and dial legibility, despite some reservations about the movement finishing and bracelet adjustability.

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.
