Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Formex Reef 39.5 mm is widely praised for its refined finishing, comfortable and well-proportioned case design, and impressive specifications for its price point, including COSC-certified Sellita SW300-1 movement and 300m water resistance. Owners and reviewers highlight the tool-less micro-adjust clasp and quick-release spring bars as practical features. Some reviewers note that the 22mm lug width feels slightly disproportionate to the smaller case, and the bracelet could benefit from more taper, though this is a point of contention for some owners who value the overall package. A prototype crown protrusion issue is noted as being addressed for production. On balance, owners and reviewers rate the Formex Reef 39.5 mm highly for its excellent value and well-executed design.
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.
