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 aesthetics and a 40mm dial size suitable for smaller wrists, with one owner noting it keeps excellent time. The watch is described as a classy, under-the-radar timepiece with simple elegance, and its cases feature rounded bezels and straight lugs reminiscent of pocket watches. Some owners find it overpriced, especially considering it historically did not use in-house movements, and one user would not pay full price, suggesting used deals. One owner reported their Portofino Automatic stopped working after being dropped, requiring a two-month repair. Overall, owners rate the IWC Schaffhausen Portofino highly for its clean aesthetics and wearability on smaller wrists.

Zelos Comet 39

Owners widely praise the Zelos Comet 39 for its wearable 39mm size, thin profile under 10mm thanks to its manual-wind Sellita SW215 movement, and its captivating dial with a deep starburst effect. The winding action is described as a joy, and the watch is considered a stunner for its price, blending modern and vintage aesthetics. Some owners note frustration with Zelos's limited production runs leading to quick sell-outs. One owner found the logo childlike, while another experienced strap-rubbing issues with the short lugs, which were resolved with a Milanese bracelet. Overall, owners and reviewers rate the Zelos Comet 39 highly for its excellent value and striking dial design.
