Description
The Seiko Prospex Alpinist GMT SPB377 is a mechanical GMT field watch built for travel and outdoor use. Its 39.5mm stainless steel case features Seiko’s super hard coating, a curved sapphire crystal with inner anti-reflective coating, and 20 bar water resistance. The blue dial is paired with Lumibrite hands and indexes for strong legibility, while the red-tipped 24-hour hand and bezel-based 24-hour display provide dual-time functionality. Powered by Seiko’s automatic Caliber 6R54 with manual winding, it delivers an approximate 72-hour power reserve and is finished with a cow leather strap and three-fold clasp with push button release.
