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 Guacamole (Gen3)

Owners widely praise the Studio Underd0g Guacamole (Gen3) for its fun, cheerful, and unusual design with great colors, and one owner found its actual wrist presence perfect. Some owners, however, find the dial printing tacky and the overall design looking cheap, while others feel it is a bit pricey for what is offered. The pushers lack crispness, and the crystal is very reflective and domed too much at the edges. One owner expresses concern that it uses a Seagull ST91-B movement, known for a high failure rate. On balance, owners are split on the value proposition of the Studio Underd0g Guacamole (Gen3) at its current price point, with some appreciating its unique aesthetic and others finding the design and movement choices underwhelming.
