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 Iw3583xx Portugieser Automatic

Owners widely praise the IWC Schaffhausen Iw3583xx Portugieser Automatic for its timeless design, comfortable 40.4mm wearability, and the Pellaton winding system of its 82200 caliber movement. Reviewers highlight the finely brushed sunray dial, applied numerals, leaf hands, and the premium feel enhanced by the double glassbox caseback. The movement itself is noted for its finishing, including perlage and côtes de Genève. Some owners find the 12.4mm case height could be thinner, and the lugs appear long, though well-curved. One owner reported the watch stopping after 6-7 hours when fully wound, contrary to the 60-hour power reserve. The 30m water resistance is considered a bare minimum for a modern watch. Overall, owners and reviewers rate the IWC Schaffhausen Iw3583xx Portugieser Automatic highly for its classic design and comfortable 40.4mm wearability at its price point.

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.
