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.

Zelos Swordfish 40mm Ti

Owners widely praise the Zelos Swordfish 40mm Ti for its comfortable titanium construction, compact size, and short lugs, noting its solid build and value. The full lume dial and bezel insert are highlighted as bright and long-lasting, with the Seiko NH35 movement's crown winding described as smoother than alternatives. Some owners note the bracelet's male end links fit perfectly without play on the 40mm case. One owner found the titanium construction ultimately unsuitable for their preferences. On balance, owners and reviewers rate the Zelos Swordfish 40mm Ti highly for its comfortable wearability and impressive lume at its price point.
