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.

Grand Seiko SBGY002

Owners and reviewers widely praise the Grand Seiko SBGY002 for its impeccable design, finishing, and attention to detail, highlighting its slender 38.5mm case and thin profile for comfortable wear. The Spring Drive movement, calibre 9R31, is noted for its accuracy within one second per day and a 72-hour power reserve, with one owner appreciating the movement's finishing and the watch's overall class and simplicity, preferring the power reserve indicator on the case back. The Snowflake dial's appearance changes with light, often appearing less yellow than expected, and a matte blue strap can make the SBGY002 more casual for daily wear, complementing the seconds hand. The Grand Seiko SBGY002 is considered a home run for its combination of iconic dial and dress case, though its yellow gold construction and price point position it differently than steel alternatives.
