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 exceptional value, with many noting its sapphire crystal, robust build, and attractive design. The Powermatic 80 variants are particularly lauded for their 80-hour power reserve and accuracy, with some reporting deviations as low as +/- 1-2 seconds per day. Owners appreciate the clean dials and practical clasps, finding the 39mm and 40mm sizes versatile. However, some owners report the crystal easily picks up fingerprints, and the stainless steel case and bracelet can show scratches or wear over time, with one instance of a bracelet falling apart after five years. Some also note that only the hands have lume, and the seconds hand may not perfectly align with markers on certain quartz models. Overall, owners rate the Tissot PR 100 highly for its impressive value and solid construction, making it a well-regarded entry-level Swiss timepiece.
