The watch is Seiko’s Presage Classic Series HCC004J1, a 145th-anniversary limited edition. Seiko specifies a stainless-steel case, not a champagne-colored one; the announcement describes the dial as inspired by raw silk. The official release also lists a dual-curved sapphire crystal and an automatic movement with a three-day power reserve.
Which Seiko watch is this?
The closest match to the “compact automatic with curved sapphire crystal” description is the Presage Classic Series HCC004, reference HCC004J1. Seiko announced it on May 14, 2026, as part of its 145th-anniversary releases. It is a limited edition rather than a regular-production Presage model.

The “champagne case” wording is not supported by Seiko’s official product specification. The listed case material is stainless steel with a super-hard coating; the official information reviewed does not identify the case as champagne-colored. Seiko instead draws attention to the dial’s texture, describing it as evoking the texture of raw silk yarn. That is a design description, not confirmation of a champagne case or a particular case color.

What the design and dimensions suggest
The compact proportions are the main practical distinction: the case is narrow across and the lug-to-lug measurement is useful for judging how much wrist space it may occupy. Thickness matters too, especially for anyone who wants a watch to slide beneath a shirt cuff. Those measurements can help narrow a fit decision, but wrist shape and strap adjustment still affect how a watch wears; trying it on is the surest way to assess comfort.
The dual-curved sapphire crystal is paired with an anti-reflective treatment on its inner surface. Seiko does not state an anti-reflective coating on the exterior in the cited specifications, so the detail should not be broadened into a claim that both surfaces are coated. The dial’s silk-yarn inspiration gives the model a material-texture theme, while the case remains specified as steel.

Caliber 6R51 is self-winding through wrist motion and also supports manual winding. The approximate reserve means a fully wound watch can continue running for roughly three days off the wrist, though the actual interval depends on its state of wind and use. That can be useful if the wearer rotates watches over a weekend, but the HCC004J1 is not presented as a quartz watch or as a watch with a stated accuracy guarantee beyond Seiko’s published daily range.
The 10-bar water-resistance rating and magnetic-resistance figure are part of the official specification, but they do not remove the need to follow Seiko’s care guidance. Water resistance can be affected by condition, seals, and maintenance, and a rating alone does not establish that an older or damaged watch remains safe for water exposure. The available product details do not specify a service interval or warranty terms.
Release timing and price
Seiko’s May 14, 2026 announcement said the watch was planned to become available from June 2026 at select retail stores worldwide. It gave a European recommended retail price of €1,050 at the time of the announcement. Seiko cautioned that specifications and prices may change. Those details do not confirm current inventory, a current selling price, or availability in any particular country as of October 13, 2026; check a Seiko Boutique or authorized local retailer for present-day status.
Who should consider it?
The HCC004J1 is most relevant to someone seeking a relatively small mechanical Presage with sapphire crystal, a textured dial concept, and a longer reserve than a typical one-day cycle. Its finite run may also appeal to anniversary-edition collectors, though the edition size by itself does not establish future value or collectability. A buyer should decide based on the steel case, actual dial appearance, fit, movement specification, and local price—not on the unverified description of a champagne case.
Seiko’s official 145th-anniversary release and HCC004J1 product specification are the primary sources for the announcement and watch details. The release-era timing and European price are dated information, while the product page supplies the listed technical specifications.
