Sinn 105 St Sa UTCvsCWC 1980 RN Divers Automatic Re-Issue Watch

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.

The CWC 1980 RN Divers Automatic Re-Issue Watch is widely praised for its faithful recreation of vintage details, including its dial layout with markers touching the chapter ring and pointed crown guards. Owners and reviewers note its reasonable size and the original minute hand design. However, the lume is a point of contention: some find the "faux patina" tint too gold and glossy, while others specifically criticize the mismatched lume color between hands and hour markers, with the hour marker lume described as overly shiny and convex. On balance, the CWC 1980 RN Divers Automatic Re-Issue Watch is highly regarded for its authentic vintage aesthetic and wearability, despite mixed opinions on the lume application.
