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.
