What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Hamilton Jazzmaster Slim Auto

The Hamilton Jazzmaster Slim Auto is praised for its elegance, light weight, and impressive leather strap, offering a classy yet engaging aesthetic. Its thin 8mm profile, achieved partly by omitting a seconds hand and utilizing the ETA 2892 movement, contributes to its wearability. However, one owner notes the 44mm case size as being very large, and another finds it less appealing than vintage Hamilton models, though the black dial version is considered better looking. Overall, owners appreciate the Hamilton Jazzmaster Slim Auto for its slim profile and elegant design.

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.
