What people say

Owners + reviewers, side by side

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

Sunrex 321

The compact 37mm case size is a strength. The watch offers versatility with included FKM rubber and leather straps.

Zelos Swordfish 3

Owners widely praise the Zelos Swordfish 3 for its strong value, with reviewers highlighting the textured sandwich dial, Seiko NH35 movement, 200m water resistance, and surprisingly good bracelet. The titanium construction is noted for making the watch compact and comfortable, weighing 117g. Some owners find the dimensions fine on paper and based on experience with other models. One reviewer flagged that legibility can suffer in bright light and bracelet edges are sharp. Overall, owners and reviewers rate the Zelos Swordfish 3 highly for its incredible value and fun design, particularly with unique dial options.
