What people say

Owners + reviewers, side by side

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

Undone Calavera Neón

The dial's vibrant colors under UV light are a standout feature. The watch uses a Seiko VK61 or TMI VK64 mechanical-quartz hybrid flyback chronograph movement.

Zelos Nova 37

Owners widely praise the Zelos Nova 37's spectacular 37mm dimensions and extremely light, thin wearability. The meteorite dial is frequently highlighted as a captivating feature, though some reviewers suggest simpler indices would improve legibility over the Arabic numerals. The watch is considered a considerable value at $1,999. On balance, owners and reviewers rate the Zelos Nova 37 highly for its excellent dimensions and dial execution at the price.

From video reviewers

The wafer-thin case and intricate dial textures are standout features. The quality of the stock leather strap is a shared concern. Reviewers differed on whether the 37mm or 38mm case size was more accurate.
