What people say

Owners + reviewers, side by side

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

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.

Tissot Seastar 1000 Powermatic 80 GMT

Owners widely praise the Tissot Seastar 1000 Powermatic 80 GMT for its excellent build quality, smooth winding feel, and the reliable Powermatic 80 movement providing an 80-hour power reserve. Reviewers highlight its remarkable value under $700, comfortable wearability, and appealing case/dial ratio. Some owners note the bezel's functionality for tracking a second time zone and the need to adjust the hour hand for date setting, a characteristic of its "True" GMT function. The rubber strap is considered comparable to those found on significantly more expensive watches. However, concerns exist regarding the movement's serviceability due to potential plastic components and reliance on Swatch Group service centers. Some find the bezel font and dial spacing unappealing, while others question the mineral glass bezel insert as a cost-cutting measure compared to ceramic. Accuracy is generally reported as good, though not COSC certified, and lume intensity is described as average by one owner.
