What people say

Owners + reviewers, side by side

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

Halios Universa II

Owners widely praise the Halios Universa II for its applied indices, excellent finishing for the price, and comfortable 38mm dimensions. The integrated bracelet design with a satisfying micro-adjust clasp and case architecture are described as masterclasses. However, some find the bracelet clasp chunkier than the overall design, and the angular lug design is noted as not being for everyone. One owner reported unexpected pastel dial colors and a poor winding action. On balance, owners rate the Halios Universa II highly for its applied indices and excellent finishing at the price point.

Studio Underd0g Full Moon

Owners widely praise the Studio Underd0g Full Moon's harmonious creamy dial and its 37mm case, which fits flawlessly. The innovative sapphire disc with numerals is a highlight, though two visible screws holding it are noted as a minor aesthetic drawback. Some owners find the watch overpriced, while others see value in the upgraded Sellita movement under $1k. Lume is surprisingly good, and the included NATO strap is preferred by some over the leather. Accuracy ranges from +1/+2 seconds per day to about -6 seconds per day. On balance, owners rate the Studio Underd0g Full Moon highly for its versatile dial and well-fitting case at the price point.
