The Seiko Prospex SPB121 revitalizes the legendary Alpinist lineage.
Tracing its roots to 1959 when Seiko introduced the Laurel Alpinist as its first sports watch designed for mountaineers and field sports enthusiasts. This modern interpretation balances heritage design cues with contemporary specifications that elevate the iconic model. At 39.5mm in diameter with a 13.2mm profile and 46.4mm lug-to-lug measurement, the stainless steel case achieves wearable proportions while maintaining commanding presence. The sunray-finish green dial creates captivating depth, its rich tone enhanced by gold accents that recall vintage British gentlemen's sporting pursuits like fly fishing and hunting.
Cathedral hands provide elegant legibility, while applied indices with LumiBrite coating ensure visibility extends into darkness. The date window at three o'clock features magnification for instant readability. The signature internal compass bezel, operated by the crown at four o'clock, enables directional orientation during outdoor adventures while maintaining the Alpinist's mountaineering heritage. Inside beats the Caliber 6R35, Seiko's robust 24-jewel automatic movement delivering an impressive 70-hour power reserve at 21,600 vibrations per hour, with both manual winding and hacking seconds capability. The curved sapphire crystal features anti-reflective coating on the inner surface for distortion-free viewing, while the screwdown crown ensures protection against the elements.
A screwdown exhibition caseback reveals the movement's mechanical operation, replacing the traditional mountain motif engraving found on earlier generations. The brown calfskin leather strap with alligator-grain embossing provides comfortable wear, secured by a tri-fold push-button clasp. Water resistance to 200 meters (20 bar) surpasses typical field watch specifications, making this timepiece capable for serious outdoor pursuits. The SPB121 represents a significant upgrade from the highly successful 2019 limited edition, now offered as part of the permanent collection with refined specifications that honor six decades of Alpinist evolution.
