Ratio Quest RTQ015 100M Sapphire Quartz “Lewis & Clark Edition” Men's Field Watch

Inspired by exploration and built for everyday adventure, the Ratio Quest RTQ015 Lewis & Clark Edition is a classic field watch combining rugged construction, excellent readability and dependable Japanese quartz accuracy.

The RTQ015 features an attractive green dial with large Arabic numerals and a secondary 24-hour scale, giving it the functional military-inspired appearance associated with traditional field watches. A date window at 3 o'clock adds everyday practicality, while luminous hands help maintain visibility after dark. (Ratiowatches)

Protecting the dial is a sapphire crystal with anti-reflective coating—an impressive feature at this price point. The compact 40mm 316L stainless-steel case is paired with a green nylon strap, making the watch lightweight and comfortable for daily wear. (Ratiowatches)

Inside is the dependable Japanese VX42 quartz movement, providing accurate, low-maintenance timekeeping. With 100 meters of pressure-tested water resistance, the RTQ015 is designed to handle an active lifestyle. (Ratiowatches)
