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.

anOrdain Model 1

Owners and reviewers widely praise the anOrdain Model 2 for its exquisite, handmade Grand Feu enamel dial, custom typeface, and syringe hands, calling it a standout feature. The 36mm steel case is noted as a thoughtful, comfortable complement to the dial, and the smooth winding action of the Sellita SW-210-1 hand-wound movement is appreciated. Some find the 5atm water resistance limiting, and the anti-reflective coating can be prone to glare. The 18mm strap width is also mentioned as potentially limiting for strap enthusiasts. On balance, owners and reviewers rate the anOrdain Model 2 highly for its stunning enamel dial and elegant, versatile design.
