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 Aurora Moonphase

Owners widely praise Zelos for offering excellent value, solid build quality, and enthusiast-friendly designs, with unique dial variants often selling out quickly. The Zelos Aurora Moonphase is noted as a desirable model, though finding one can be challenging. Some owners find Zelos's designs, including those of the Aurora line, to be too flashy for everyday wear, preferring a more subdued aesthetic. One owner reported their Zelos Aurora Nebula 38mm running at -5.3 seconds per day. Overall, owners rate the Zelos Aurora Moonphase highly for its desirable microbrand status and unique dial appeal.
