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 aesthetic and refined dial details, with many finding the 40mm size perfect for smaller wrists and noting its ability to provide a spark of joy. Some owners admire the dial color in sunlight and the versatility offered by changing straps. One owner notes its modified Sellita SW300/ETA 29xx movement is reliable and accurate, and another reports excellent timekeeping, with IWC reportedly maintaining chronometer standards. However, some find the Portofino overpriced and less valuable compared to watches with in-house movements. One owner reported their watch stopped working immediately after being dropped and required a lengthy repair. On balance, owners and reviewers rate the IWC Schaffhausen Portofino highly for its classical sophistication and understated elegance.

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.
