The Seiko Prospex "Alpinist" is a men's mechanical watch with a classic round design. It suits outdoor activities such as trekking and mountaineering, and it also works for everyday wear.
It is powered by the automatic-winding Caliber 6R35, which can also be wound by hand. It has 24 jewels, a stop-seconds function and a date calendar. An internal rotating compass ring is used for simple orientation.
The 39.5 mm stainless steel case has a sapphire crystal with an anti-reflective coating on the inner surface. The hands and indexes have Lumibrite. A see-through case back shows the movement. The strap is calfskin leather with a three-fold clasp and push-button release.
