The Seiko Prospex Alpinist GMT SPB379 is a tribute to Seiko's 1959 Alpinist, a watch revered for its durability and outdoor functionality. Its classic black dial, marked with distinctive wedges, bold numerals, and stylized hands, mirrors the original design. The GMT feature, with a 24-hour hand, facilitates tracking of a second time zone, ideal for travelers.
Enhancements include a curved sapphire crystal with an inner anti-reflective coating for enhanced visibility, and an inner rotating compass bezel, tailored for hiking and outdoor pursuits. LumiBrite hands and markers ensure clear reading in low light. The automatic 24-jewel movement, visible through the transparent screwdown caseback, operates at 21,600 vibrations per hour, boasting an impressive 72-hour power reserve and manual winding capability.

Constructed from stainless steel with a durable super-hard coating, it’s built to endure. The screw down crown ensures water resistance, up to 200 meters (20 bar), suitable for swimming and snorkeling. A black calf leather strap, secured with a tri-fold push-button release clasp, combines comfort with style.

The Prospex Alpinist SPB379 merges timeless design with contemporary enhancements, offering a reliable companion for adventurers and outdoor enthusiasts. Its robust build, water resistance, GMT functionality, and extended power reserve make it adaptable to a wide range of activities.
