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 XS

Owners widely praise the Sternglas Naos XS for its simple, awesome design, domed sapphire crystal, and clean hands, with one owner highlighting the beautiful blue mother-of-pearl dial and top-notch build quality on a special edition. It is recommended as a durable, refined daily wear watch for around $270, suitable for casual and formal occasions. However, one owner found the Sternglas Naos XS to have a cheap feel and a face resembling a toy, noting it wears smaller than expected, while another described the automatic movement as a bit noisy. On balance, owners rate the Sternglas Naos XS highly for its refined design and value, with specific praise for the mother-of-pearl dial on special editions.

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.
