The Prospex Alpinist 38mm SPB155 by Seiko is a classic design reduced to the essentials. The 38 mm stainless steel case houses the Seiko 6R35 calibre (automatic, approx. 70 hrs power reserve). Sapphire glass and 200 m water resistance put the watch into practical perspective; it is worn on a stainless steel bracelet, day to day and outdoors. A design that will still look right in ten years.
