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.

Horage Supersede GMT

The Horage Supersede GMT is widely praised for its innovative micro-rotor movement and impressive finishing. Owners and reviewers highlight its value as a true GMT sports watch, noting the compact 39.5mm case and 200m water resistance. The K2 movement offers a 72-hour power reserve, and updates include an optional platinum rotor, a luminous seconds hand tip, and a new micro-adjustable clasp. One potential hesitation for buyers is the inability to see the watch in person. Overall, owners and reviewers rate the Horage Supersede GMT highly for its innovative micro-rotor movement and excellent value.

From video reviewers

The Horage Supersede GMT features a unique case design that blends different styles. A notable strength is its in-house K2 micro-rotor movement. One weakness is the relatively average lume brightness.
