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 Iw658601 Portofino Automatic

Owners widely praise the IWC Schaffhausen Iw658601 Portofino Automatic's elegant, simple design and thin 9.4mm case, making it a versatile dress watch suitable for everyday wear. Its classical look, rounded bezel, and sunburst dial are frequently highlighted as attractive features. Some owners find the 37mm case size comfortable and appreciate its slim profile, contrary to perceptions of IWC watches being bulky. Accuracy reports vary, with one owner noting excellent timekeeping and another observing a loss of almost 10 seconds per day. The value proposition is debated, with some questioning the use of an external movement at its price point. On balance, owners and reviewers appreciate the IWC Schaffhausen Iw658601 Portofino Automatic for its classic dress watch aesthetic and wearability, though some debate its value.

Grand Seiko SBGH368

The Grand Seiko SBGH368 is praised for its aggressive styling and textured copper-pink dial, inspired by cherry blossoms. Reviewers highlight its 38mm 18k rose gold 62GS case, featuring Zaratsu polishing, as a standout element. The watch is powered by the Hi-Beat Caliber 9S85 movement, which is regulated to -3/+5 seconds per day and offers a 55-hour power reserve. It also features 100m water resistance. One reviewer notes that the brown crocodile strap, while handsome, would ideally be replaced with a water-resistant option given the watch's 100m water resistance. There is also a question raised about whether a movement with a longer power reserve could have been utilized. The Grand Seiko SBGH368 retails for $31,200. Overall, reviewers consider the Grand Seiko SBGH368 a favorite gold-cased Grand Seiko, with its rose gold case and cherry blossom dial described as an exceptional combination.
