What people say

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 Naos Automatik

The Sternglas Naos Automatik is praised for its stylish Bauhaus design and solid build quality for its price, featuring a sapphire crystal and elegant case. However, some dial text is too small and slim for easy readability, and the Milanese strap and clasp are considered lower quality, with the quick-change system also not meeting the brand's advertised standard. One owner found the 38mm model lighter than expected and preferred it over a Seiko SRP703 and an Apple Watch. Overall, owners and reviewers highlight the Sternglas Naos Automatik's attractive Bauhaus design and good value, despite some criticisms of dial legibility and strap quality.
