What people say

Owners + reviewers, side by side

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

Breitling Chronomat Automatic 36

Owners widely praise the Breitling Chronomat Automatic 36 for its comfortable 36mm case size, excellent fit and finish, and the unique appeal of its dials, with the blue and green variants frequently highlighted. The Rouleaux bracelet is consistently noted as very comfortable and a standout feature, connecting the watch to its Chronomat heritage, while the anti-reflective coating and color-matched date wheel enhance its visual appeal. Some owners find the styling slightly feminine, and its marketing as a ladies' line is questioned, though it is broadly seen as a versatile unisex option that fits well on smaller wrists. The $10,950 price is considered a stretch by one reviewer, particularly given the bezel gems and strap. Overall, owners and reviewers rate the Breitling Chronomat Automatic 36 highly for its comfortable wearability and distinctive dial and bracelet design.

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.
