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.

NOMOS Glashütte Lambda 39

The NOMOS Glashütte Lambda 39 is celebrated for its spare clarity, minimalist purity, and Bauhaus dial design with excellent legibility. Owners and reviewers praise its well-integrated power reserve complication, which boasts 84 hours of power reserve, and the gorgeous, in-house hand-wound caliber DUW 1001 featuring Glashütte finishing like a three-quarter plate, hand beveling, and an engraved balance cock. Some find the full gold case and giant power reserve display well worth its price for the fine horology and minimalist elegance, though others note a clash between the oversized power reserve display and dial design, and dislike the lettering on the indicator. The high price point for gold models, $18,000-$20,000, is considered steep by some, representing a significant departure from NOMOS's typical offerings.
