Owners + reviewers, side by side

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

IWC Schaffhausen Iw3565 Portofino Automatic

Owners widely praise the IWC Schaffhausen Portofino for its clean, classic dress watch aesthetic and refined dial details, with many finding the 40mm size perfect for smaller wrists and noting its ability to provide a spark of joy. Some owners admire the dial color in sunlight and the versatility offered by changing straps. One owner notes its modified Sellita SW300/ETA 29xx movement is reliable and accurate, and another reports excellent timekeeping, with IWC reportedly maintaining chronometer standards. However, some find the Portofino overpriced and less valuable compared to watches with in-house movements. One owner reported their watch stopped working immediately after being dropped and required a lengthy repair. On balance, owners and reviewers rate the IWC Schaffhausen Portofino highly for its classical sophistication and understated elegance.

Sternglas Kanton

The Sternglas Kanton is praised for its refined Bauhaus-inspired design, featuring a silver-plated dial and luminous hands and dots for excellent legibility. Owners and reviewers highlight its comfortable 39mm case size, measuring 10mm thick, and the visible STP 1-11 automatic movement through a sapphire crystal case back. Accuracy figures vary, with one source noting +15 seconds per day, while another suggests improved accuracy over previous models. Overall, owners and reviewers rate the Sternglas Kanton highly for its blend of Bauhaus design and Swiss precision at an affordable price point.
