Reviews

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 Iw3565 Portofino Automatic for its clean, classic dress watch aesthetic and 40mm size, which is considered perfect for smaller wrists. Reviewers and owners alike highlight its dial color in sunlight, refined dial details, and overall sophisticated appearance. One owner notes it keeps excellent time, with IWC reportedly maintaining chronometer standards. However, some find its use of an external movement and its price point less valuable compared to watches with in-house movements, with one owner suggesting avoiding full retail price. One owner reported their watch stopped working immediately after being dropped. Overall, owners and reviewers rate the IWC Schaffhausen Iw3565 Portofino Automatic highly for its classic dress watch design and wearability.

Seagull Ultra-Thin Calendar Dress Watch 38mm

Owners widely praise the Seagull Ultra-Thin Calendar Dress Watch 38mm for its appealing thinness, well-balanced 38mm size that wears well on smaller wrists, and the smooth operation of its automatic movement. The polished finishing is noted as well-done, and its Bauhaus styling with a clean dial and curved lugs is a positive differentiator. However, one owner finds the watch too thick for a true dress watch, believing a dress watch should be thinner to fit under a cuff. Overall, owners rate the Seagull Ultra-Thin Calendar Dress Watch 38mm highly for its wearability and aesthetic at the price point.
