What people say

Owners + reviewers, side by side

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

Sternglas Naos

The Sternglas Naos is widely praised for its refined daily wearability and Bauhaus design, with owners noting its durable construction, scratchless sapphire crystal, and flawless date mechanism. Reviewers highlight the comfortable and supple bracelet that drapes well and a date window that matches the dial. One owner advises replacing the original tan strap due to a lack of durability. The quartz movement is noted for its accuracy, and the absence of a seconds hand is seen as a unique solution to prevent misaligned markers. Overall, owners and reviewers rate the Sternglas Naos highly for its harmonious design and comfortable wear at its price point.

Tissot PR 100

Owners widely praise the Tissot PR 100 for its excellent value, with specific mentions of its sapphire crystal, 100m water resistance, and the 80-hour power reserve of its Powermatic 80 movement. Reviewers and owners consistently highlight its pleasing winding action and strong lume. Accuracy figures for the Powermatic 80 COSC variants are reported as -2 seconds per day or +/- 1-2 seconds per day. Some owners note that the crystal attracts fingerprints and that the black finish on some bracelets can wear off after extended daily use. A single owner of a quartz model experienced a recurring issue where the watch stopped for periods weekly, which was not resolved by a battery replacement. Overall, owners and reviewers rate the Tissot PR 100 highly for its exceptional value and robust features, particularly its durable construction and reliable movements.
