What people say

Owners + reviewers, side by side

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

Henry Archer Tidslinje

Owners widely praise the Henry Archer Tidslinje for its superb build quality, captivating dial designs, and comfortable wearability, with many highlighting its 40mm size and 12.1mm thickness as very wearable. The triple date function is appreciated for its utility and collection variety, and the beads of rice bracelet is frequently noted for its comfort and quality. Accuracy figures vary, with some owners reporting +/- 2-4 seconds per day and others around 10-15 seconds per day as advertised. Some owners find the day/month indicators and the numbering for days of the week to be tiny and hard to read, and the black bezel is considered disproportionately large and cosmetic by some. One owner noted disappointment that a micro-adjust clasp is no longer offered on the Lunaris model. Overall, owners rate the Henry Archer Tidslinje highly for its captivating design and excellent value for money.

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.
