Inspired by Seiko's legendary Alpinist collection, the Prospex Alpinist Mechanical GMT combines adventure-ready functionality with timeless design. The 39.5mm stainless steel case is paired with a rich green dial and a brown leather strap, while the automatic GMT movement delivers a 72-hour power reserve for reliable performance on every journey. A rotating compass inner ring, sapphire crystal, and exhibition case back complete this versatile timepiece, designed for exploration on and off the trail.
