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.

Sinn U18

The Sinn U18 is praised for its unique deep blue/green dial with three-dimensional oxygen bubbles that change with light, and its comfortable, easily adjustable bracelet. Owners find the watch stunning and a piece of history, appreciating the refined hands. The Sinn U18 features a 44mm, 15.5mm thick case made from German submarine steel, offering a 2000-meter dive specification and Sinn's Ar-Dehumidifying technology, powered by a Sellita SW300-1 movement. The case thickness is apparent, and the watch comes as a complete set with box and papers for $3,000-$3,680. On balance, owners and reviewers rate the Sinn U18 highly for its striking dial and robust build.
