The Seiko “Contra” as it’s called is a vintage field watch also known as the “Fieldmaster.” These watches were produced in the 1980’s and are hard to find. These watches consisted of two 28mm. interchangeable modules extending to 60mm. when measuring both. The watch features the cool map reading module. When the the wheel is rolled on a map, the watch will indicate mileage based on the scale. The other is a great looking Seiko quartz. This watch is in great overall condition. A prime example here.
