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.

Loresum LS05

Owners widely praise the Loresum LS05 for its elegant dial execution, particularly the aventurine and Great Wave designs, and its attractive dimensions, including a thin profile. The moonphase complication is a significant draw, with many finding it a compelling feature at its price point, and the overall finishing is considered well done. However, some owners find the watch too dressy for everyday wear, and the included strap is noted as being of low quality. One owner reported excellent customer service for a repair. The Miyota 9015 movement is standard, with its moonphase cycle drifting over time and reversing lunar waxing/waning. On balance, owners rate the Loresum LS05 highly for its visually striking dials and value proposition, especially for its moonphase complication.
