What people say

Owners + reviewers, side by side

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

Spinnaker Dumas GMT

Owners praise the Spinnaker Dumas GMT's satisfying lume, including on the crown, and good finishing, with one owner finding it wears well on a 17cm wrist. The watch features a Seiko NH34A GMT movement and a blue gradient dial. Reviewers note its 44mm diameter and 209g weight on the bracelet make it unsuitable for smaller wrists.

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.
