What people say

Owners + reviewers, side by side

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

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.

Longines HYDROCONQUEST GMT

Owners widely praise the Longines HYDROCONQUEST GMT for its excellent finishing, smooth winding action, and overall value, with some finding its build quality and colorways superior to higher-priced competitors. Reviewers and owners alike note its robustness as a traveler's dive watch with a true GMT movement. Some owners find the round markers at 6 and 9 disrupt dial symmetry, and the GMT hour markers are described as tiny and difficult to read. The date wheel can be mismatched on certain dial colors, and the bracelet clasp is noted as sharp by one reviewer. While some owners wish for a smaller case size, others find the 41mm comfortable. The bezel action is flagged as having bounce-back by one owner, though the brushed finish effectively hides wear. Overall, owners and reviewers rate the Longines HYDROCONQUEST GMT highly for its robust build and excellent value proposition.
