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 2 OT

Owners and reviewers widely praise the anOrdain Model 2 OT for its exquisite, handcrafted vitreous enamel dial and harmonious design. The 36mm steel case is noted for its simple, rugged field watch inspiration, and the winding experience is described as exceptionally smooth. Some reviewers flag a low 5atm water resistance and noticeable glare on the crystal, while others mention the lack of a seconds hand and limited lume. The 36mm case size is perceived differently, with some finding it wears larger and others smaller than expected. Overall, the consensus is that the anOrdain Model 2 OT is a highly regarded piece for its artistic dial and craftsmanship at its price point.
