Owners widely praise the IWC Schaffhausen Iw357415 Portofino Automatic for its clean, classic dress watch aesthetic and elegant, minimalist design, with many appreciating its slim profile. One owner highlights the appealing blue dial color, while another notes it keeps excellent time. However, some question its value proposition, especially given the use of an external movement and its price point relative to competitors. One owner found the watch had a larger presence on the wrist than expected. Overall, owners rate the IWC Schaffhausen Iw357415 Portofino Automatic highly for its classic dress watch aesthetic and elegant design.

The Sternglas Naos Pro Automatik is praised for its slim 9mm case and Bauhaus dial design, featuring clear hour markers and a framed date window. Owners note the upgraded Miyota 9015 movement with a 4Hz beat rate. Accuracy is reported as -10/+30 seconds per day, which is not ideal for precision enthusiasts. The five-link bracelet's lack of fitted end-links and the optional bracelet's chunkiness are flagged as areas lacking refinement. Overall, reviewers highlight the Sternglas Naos Pro Automatik's improved wearability and premium feel at its price point.
