What people say

Owners + reviewers, side by side

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

Breitling Superocean Heritage B31 Automatic

Owners widely praise the Breitling Superocean Heritage B31 Automatic for its excellent finishing and comfortable wearability, with many appreciating the sunburst dials and the redesigned mesh bracelet. The watch is noted for its versatile design, suitable for daily wear and swimming, and some owners find its weight surprisingly manageable due to the lug shape and bracelet design. The Breitling B31 movement offers a 78-hour power reserve and COSC certification. However, the watch's design is divisive, with some disliking its aesthetic and others criticizing the use of a Sellita SW200 movement at its price point, though discounts are seen to mitigate this. Some owners also find the watch too large for smaller wrists due to its lug-to-lug distance, and the white date display at 6 o'clock is a point of contention for some. Overall, owners rate the Breitling Superocean Heritage B31 Automatic highly for its finishing and comfortable wearability, despite some design and movement criticisms.

Marathon GSAR (Government Search & Rescue) Diver's Automatic

The Marathon GSAR (Government Search & Rescue) Diver's Automatic is widely praised for its legibility, comfort, and exceptional tritium illumination, with reviewers highlighting its utilitarian, military-equipment feel and a 41mm case size considered ideal. Owners appreciate its grippy bezel and the 300 meters of water resistance provided by the screw-down crown, deeming it a solid value for a Swiss-made tool watch. Some owners report quality control issues, with one user needing to warranty two watches, and another notes the GSAR wears taller than other models, leading to occasional bumping. The reliable ETA 2824-A2 movement is a consistent feature. Overall, owners and reviewers rate the Marathon GSAR (Government Search & Rescue) Diver's Automatic highly for its bright tritium lume and robust, no-nonsense tool watch design.
