The Seiko Presage Classic Series (ref. spb521j1) is an automatic dress watch, with a 36mm stainless steel case, 12.5mm thick, powered by the 6R51 movement and a 72-hour power reserve. Water resistance is rated to 100m, under a sapphire crystal. Manufacturer MSRP is $950.
The Seiko Presage Classic Series is widely praised for its sublime dial and hand finishing, with textured dials inspired by silk and elegantly curved hands. Owners and reviewers highlight the value proposition under $1,000, the comfortable wearability due to case proportions and slim appearance, and the robust 100m water resistance on several models. The 72-hour power reserve from the 6R51 or 6R55 automatic movements is a consistent positive note. However, one owner criticizes the pin and collar bracelet system as awful, and the 24-hour subdial is noted as potentially annoying by another. Accuracy figures for the 6R55 movement range from +25/-15 seconds per day to within -15/+25 seconds per day. On balance, owners and reviewers rate the Seiko Presage Classic Series highly for its exquisite dial work and strong value at its price point.
