Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Sinn 104 Classic 12 is widely praised for its excellent legibility, comfortable wearability, and overall quality, with one owner deeming it the best watch under $3000 for their needs. Reviewers and owners alike highlight the bidirectional bezel action as a strong point, and the H-link bracelet is noted as sturdy and comfortable. However, one reviewer finds the handset and "Automatik" font slightly at odds with the dial, and another commenter describes Sinn watches as too thick with "plasticky" hands and an inner bezel edge that doesn't match promotional images. The watch is priced at €1,750, and its H-link bracelet lacks modern quick-release or micro-adjustment features. On balance, owners and reviewers rate the Sinn 104 Classic 12 highly for its pilot's tool functionality and value.
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.
