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

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is housed within, with one reviewer calling its accuracy rating of -15/+25 seconds per day and 3 Hz frequency somewhat outdated for the watch's price.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.
