The Seiko Presage Classic Series “Craftsmanship” Arita Porcelain Dial (ref. spb445j1) is an automatic dress watch, with a 40.6mm stainless steel case, 12.5mm thick, powered by the 6R5H movement and a 72-hour power reserve. Water resistance is rated to 100m, under a sapphire crystal. Manufacturer MSRP is $1,900.
Owners and reviewers widely praise the Seiko Presage Classic Series “Craftsmanship” Arita Porcelain Dial for its unique, smooth, and lustrous porcelain dial, a testament to meticulous Japanese craftsmanship, with some noting its depth and subtle color variations. The red "XII" and recessed sub-dials on certain variants are highlighted as distinctive design elements. However, multiple sources flag the case thickness, ranging from 12.4mm to 14.1mm, as substantial for a dress watch, and one reviewer criticizes painted hands instead of heat-blued ones. Accuracy figures are not consistently reported across sources, with one owner noting figures around +1/+2 seconds per day while another mentions approximately -6 seconds per day. On balance, owners and reviewers rate the Seiko Presage Classic Series “Craftsmanship” Arita Porcelain Dial highly for its exceptional dial artistry and craftsmanship at its price point.
