Seiko Presage Classic Series “Craftsmanship” Unglazed Arita Porcelain Dial Limited EditionvsSinn U18

Seiko Presage Classic Series “Craftsmanship” Unglazed Arita Porcelain Dial Limited Edition owners and reviewers widely praise its beautiful, powdery cream unglazed Arita porcelain dial with a rhombus pattern, contrasting elegantly with gold-toned hands and indices. The 40.6mm stainless steel case is noted for its overall finishing, though some find it thick and heavy. The 72-hour power reserve 6R51 automatic movement is housed within, with one reviewer calling its accuracy rating of -15/+25 seconds per day and 3 Hz frequency somewhat outdated for the watch's price. A notable omission for some is the lack of lume, particularly on the hands. Overall, owners and reviewers rate the Seiko Presage Classic Series “Craftsmanship” Unglazed Arita Porcelain Dial Limited Edition highly for its stunning dial and craftsmanship at the price, despite some reservations about its thickness and movement specifications.

The Sinn U18 is praised for its unique deep blue/green dial with three-dimensional oxygen bubbles that change with light, and its comfortable, easily adjustable bracelet. Owners find the watch stunning and a piece of history, appreciating the refined hands. The Sinn U18 features a 44mm, 15.5mm thick case made from German submarine steel, offering a 2000-meter dive specification and Sinn's Ar-Dehumidifying technology, powered by a Sellita SW300-1 movement. The case thickness is apparent, and the watch comes as a complete set with box and papers for $3,000-$3,680. On balance, owners and reviewers rate the Sinn U18 highly for its striking dial and robust build.
