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 XS

Owners widely praise the Sternglas Naos XS for its simple, awesome design, domed sapphire crystal, and clean hands, with one owner highlighting the beautiful blue mother-of-pearl dial and top-notch build quality on a special edition. It is recommended as a durable, refined daily wear watch for around $270, suitable for casual and formal occasions. However, one owner found the Sternglas Naos XS to have a cheap feel and a face resembling a toy, noting it wears smaller than expected, while another described the automatic movement as a bit noisy. On balance, owners rate the Sternglas Naos XS highly for its refined design and value, with specific praise for the mother-of-pearl dial on special editions.

Zelos Helica

Owners widely praise the Zelos Helica for its stunning, often color-shifting dials, with specific mentions of the MoP, slate grey, 'Steel Blue', and red opal variants being particularly captivating and artful. The 39mm case size is noted as fitting well on smaller wrists, and the overall build quality and finishing for the price are frequently highlighted as impressive, with one owner calling it "a lot of watch for the price." Some owners appreciate the novel bracelet designs and full lume dials, while others find the bracelet and clasp edges sharp or the clasp lacking on-the-fly adjustment. Opinions on the date window are mixed, with one owner disliking it. The Zelos Helica Moonphase was considered cluttered by one owner, and its $1K USD price point was felt to be steep by another, though popular variants sold out rapidly. Overall, owners rate the Zelos Helica highly for its striking dial designs and impressive value proposition.
