The Seiko Prospex Alpinist Mechanical GMT HBC009J introduces the first-ever GMT complication to the Alpinist line — a Seiko Global Brand Core Shop exclusive built on the DNA of the 1959 Laurel Alpinist, Seiko's first dedicated sport watch. HBC009J's black dial and matching black leather strap keep the Alpinist's classic field-watch character front and center. The 39.5mm case houses the newly developed Caliber 6R54 automatic movement with a 72-hour power reserve, paired with a compass-equipped inner bezel. The red-tipped 24-hour GMT hand and hairline-finished bezel give the second-timezone display genuine field-watch legibility, while the curved sapphire crystal with inner anti-reflective coating and Dia-Shield case coating bring the finish up to premium sports-watch standard. Japan-only, Core Shop distribution-limited model.
*Pre-Order! Release scheduled for September 2026.*
Key Features:
- Caliber 6R54 — Alpinist's First GMT Movement: A newly developed automatic caliber with manual winding capability, 72-hour power reserve, 24 jewels, and a 24-hour GMT hand for true dual-time display — the first time a GMT complication has been built into the Alpinist line.
- Compass Inner Bezel — Alpinist Field-Watch Heritage: The inner rotating ring doubles as a simplified compass when the GMT hand is used as a 24-hour hand, continuing the mountaineering functionality that has defined Alpinist since the original 1959 Laurel Alpinist.
- Black Dial & Black Leather Strap: A classic, versatile black-on-black colorway with the same wedge indices, Arabic numerals at 12/3/6/9, and red-tipped GMT hand as its blue sibling — same case, same movement, different mood.
- Dia-Shield Case & Curved Sapphire Crystal: The stainless steel case is finished with Dia-Shield coating for scratch resistance, paired with a curved sapphire crystal featuring inner anti-reflective coating for clean legibility. See-through screw caseback and screw-lock crown complete the tool-watch spec sheet.
- Seiko Global Brand Core Shop Exclusive: Distribution limited to Seiko's designated Core Shops in Japan — not sold through general retail channels.
