Reviews

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

Thorn Titanium

Owners widely praise the Cronos Thorn PT5000 Automatic 39mm Titanium Watch SHY036 for its value, with one owner calling it the best modern explorer homage under $170. The tool-free bracelet adjustment links are considered a game-changer, and the 39mm titanium case is noted as unobtrusive and keeping the watch under 11mm thick. The PT5000 movement's accuracy is a point of varied owner experience, ranging from exceptional timekeeping comparable to quartz, to running 2.8 seconds fast per day, or gaining 2.5 minutes over two weeks. Some owners express skepticism or disappointment with the PT5000 movement, with one finding it noisy and finicky, and another preferring Seiko alternatives. Overall, owners rate the Cronos Thorn PT5000 Automatic 39mm Titanium Watch SHY036 highly for its excellent value and practical bracelet features, despite mixed experiences with the PT5000 movement's accuracy.

Seestern Ocean Star S450-2.EC

A reviewer suggests improvements could be made to the case finishing and handset size, while highlighting the desirable cast lume. Overall, owners rate the Seestern Ocean Star S450-2.EC highly for its exceptional bracelet and clasp at the price point, with the cast lume also being a noted positive.
