Seiko Prospex HBC006J1 – 145th Anniversary Limited Edition

The Seiko Prospex Alpinist HBC006 145th Anniversary Limited Edition brings one of Seiko’s most distinctive outdoor watch designs into a striking new expression inspired by Edo Purple, a traditional Japanese color. Created to celebrate Seiko’s 145th anniversary, this limited-edition mechanical watch combines the heritage of the Alpinist collection with refined Japanese craftsmanship and modern everyday performance.

The Alpinist traces its roots to Seiko’s 1959 Laurel Alpinist, the brand’s first sports watch. That heritage is reflected in the classic dial architecture, distinctive Alpinist branding, and practical field-watch character. For the HBC006, Seiko pairs a sophisticated purple dial with a subtle sunray finish, complemented by gold-tone accents and a black leather strap featuring coordinated purple stitching.

At its heart is Seiko’s Caliber 6R55 automatic movement, featuring both automatic and manual winding, 24 jewels, a 21,600 vibrations-per-hour frequency, and an impressive approximately 72-hour power reserve. This extended autonomy makes the watch particularly convenient for collectors who rotate between multiple timepieces.

The 39.5mm stainless steel case offers a versatile presence on the wrist, while the sapphire crystal with inner anti-reflective coating provides excellent scratch resistance and readability. A 20-bar (200m) water-resistance rating, screw-down crown, LumiBrite hands and indexes, and an internal rotating compass bezel reinforce the Alpinist’s practical field-watch credentials.

Limited to just 7,000 pieces worldwide, the Seiko Prospex HBC006 is an especially compelling choice for collectors seeking a distinctive anniversary Seiko with genuine historical significance. The exhibition case back reveals the mechanical movement and carries the Limited Edition designation, adding to its collectible appeal.

For U.S. collectors searching for a Seiko Alpinist limited edition, an automatic Seiko Prospex watch, or a distinctive Japanese mechanical watch, the HBC006 offers a rare combination of heritage, functionality, and exclusivity. Discover the Seiko Prospex HBC006 145th Anniversary Limited Edition at Lexor Miami.
