What people say

Owners + reviewers, side by side

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

Sinn 105 St Sa UTC

Owners and reviewers widely praise the Sinn 105 St Sa UTC for its legible dial, precise bi-directional bezel action, and the technical, toolish aesthetic of its bead-blasted, TEGIMENT-hardened steel case. The watch is noted for its smooth sweep and snappy date change, with accuracy often within COSC standards, and its vertical day/date display with a German day wheel is a distinctive feature. Some owners find the lug-to-lug distance large for smaller wrists, and the bracelet clasp is considered a weakness by one source, while the non-lumed UTC hand is a deliberate design choice. The Sinn 105 St Sa UTC utilizes a Sellita SW330-1 automatic movement with a 42-hour power reserve and offers 200 meters of water resistance. Overall, the consensus is that owners and reviewers rate the Sinn 105 St Sa UTC highly for its robust build quality and functional tool watch design at its price point.

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.
