Featuring the collection’s signature deep green sunburst dial, gold-tone accents, cathedral hands and internal rotating compass bezel, the SPB121 retains much of the character that made its predecessor, the SARB017, a modern Seiko classic.\u003c\/p\u003e\n\u003cp\u003eAt just under 40mm, the SPB121 combines compact proportions with 200 meters of water resistance and the longer-running 6R35 automatic movement, creating a versatile modern sports watch with a distinctly vintage appearance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHistory:\u003c\/strong\u003e\u003cbr\u003eThe Alpinist lineage can be traced back to the Laurel Alpinist of 1959, Seiko’s first watch developed specifically with recreational and outdoor use in mind. Over the following decades the Alpinist evolved considerably, eventually developing the distinctive internal compass bezel and dual-crown architecture now strongly associated with the collection.\u003c\/p\u003e\n\u003cp\u003eIntroduced in 2020, the SPB121 succeeded the immensely popular SARB017. While retaining its predecessor’s green-and-gold aesthetic, Seiko repositioned the Alpinist within the Prospex collection and introduced several technical upgrades, most notably a sapphire crystal, increased 200-meter water resistance and the Caliber 6R35 with approximately 70 hours of power reserve.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications and Condition:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOverall: Great Condition\u003cbr\u003eCase: Great Condition\u003cbr\u003eCrystal: Clean\u003cbr\u003eDial: Clean\u003cbr\u003eMovement: Excellent\u003cbr\u003eBracelet\/Strap: Original Seiko Leather Strap\u003cbr\u003eIncludes: Watch\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMovement:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSeiko Caliber 6R35 Automatic\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e39.5mm Case Diameter\u003cbr\u003e46.4mm Lug-to-Lug\u003cbr\u003e13.2mm Thickness\u003cbr\u003e20mm Lug Width\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDesign Details:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eDeep Green Sunburst Dial\u003cbr\u003eGold-Tone Applied Hour Markers\u003cbr\u003eGold-Tone Cathedral-Style Hands\u003cbr\u003eInternal Rotating Compass Bezel\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eClosing Note:\u003c\/strong\u003e\u003cbr\u003eThe SPB121 successfully carries one of the most recognizable modern Seiko designs into the current Prospex generation.
