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 Watermelon (Gen3)

Owners widely praise the Studio Underd0g Watermelon (Gen3) for its fun, entrepreneurial, and affordable nature, with a design described as "Bauhaus meets Bugs Bunny." However, some find its colors a love-it-or-hate-it feature and others perceive the overall quality and finishing as a tier below comparable watches. Accuracy figures are not specified, but one owner found the watch too thick for their taste. The chronograph function has been noted as potentially sticky or jumpy. On balance, owners are divided on the Studio Underd0g Watermelon (Gen3), with opinions split between its unique design and perceived value for money.

Zelos Spearfish GMT

The Zelos Spearfish GMT is widely praised for its exceptional value, with reviewers highlighting its superb finishing, flawless machining, and a tool-less micro-adjustment clasp that exceeds its price point. It features a La Joux-Perret G100 movement with a 68-hour power reserve, achieving an average accuracy of +2.6 seconds per day, or a Miyota 9075 movement offering flier-style GMT functionality. The 40mm case and bidirectional 48-click ceramic bezel are well-executed, though one reviewer noted a minor compromise in the end link fit. Overall, owners and reviewers rate the Zelos Spearfish GMT highly for its impressive finishing and value proposition.
