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 Mint Choc Chip (Gen3)

Owners and reviewers praise the Studio Underd0g Mint Choc Chip (Gen3) for its unique, visually striking design, featuring an asymmetrical dial, textured two-tone finish, orange chrono hand tips, and chocolate chip hour markers, all housed in a comfortable 38.5mm case with a hand-winding SeaGull ST-1901 movement and a goat-skin strap. Some owners, however, find the watch overpriced for its movement and dial quality, and a few feel it appears toy-like on larger wrists. Overall, owners and reviewers value the Studio Underd0g Mint Choc Chip (Gen3) for its distinctive aesthetic and comfortable wear, despite some reservations about price and perceived scale.
