What people say

Owners + reviewers, side by side

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

anOrdain Model 1 (Group Buy)

Owners widely praise the anOrdain Model 1 (Group Buy) for its exceptional vitreous enamel dial, custom typography, and elegant, handmade aesthetic. The dial's deep colors and light-reflecting properties are frequently highlighted as a standout feature, with crisp printing and legible layouts. One owner notes the case finishing is basic but well-executed with a high-polish finish and defined lugs. The watch is considered worth the wait and looks better in person, becoming a daily wearer for some. However, long wait times from deposit to delivery, sometimes nearly two years, are a significant drawback. The Sellita SW200-1 movement is standard with a 38-hour power reserve, and one reviewer wished the 12.3mm case was slimmer. Another owner found the case plain and the buckle thin, while also noting white hands could crowd dial numbers on a GMT variant. Accuracy figures vary, with one owner reporting good timekeeping and another noting the watch is keeping good time.

From video reviewers

The enamel dial is a standout feature. Legibility issues were addressed by reluming the hands.

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.
