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 Solar

Owners widely praise the Sternglas Naos Solar for its elegant Bauhaus-inspired minimalist dial, slim profile, and value for money. The scratch-resistant curved sapphire crystal and functional date mechanism are noted as durable features, with one owner reporting good wear over a year. The solar power and accuracy are highlighted as practical advantages over automatic movements, which some find loud. However, opinions are split, with some owners finding the watch underwhelming and cheap-looking, like a toy, while others love its appearance in person and its clean, appealing design as a smartwatch alternative. The stock leather strap is described as decent but basic and potentially short for larger wrists, with one owner advising a third-party replacement for durability. One owner of a different variant noted the date font is too small to be useful.

Zelos Thresher 44

Owners widely praise the Zelos Thresher 44, with one owner noting its finish has proven remarkably scratch-resistant. However, one owner found the finishing on their hammered grey variant not as well done as expected. The Zelos Thresher 44 with an agate dial sold out in 90 seconds, with one owner receiving theirs and noting the bracelet was fully wrapped. Overall, owners rate the Zelos Thresher 44 highly for its desirability and scratch-resistant finish.
