Wrapped in a stylish polished titanium carbon nitride case, this Seiko men's alarm chronograph dress watch can measure up to 60 minutes in 1/5 second increments. After 60 minutes it will start counting again from zero, repeatedly up to 12 hours. The alarm can be set on a 12-hour basis with two small hands. Alarm hands can indicate the time in a different time zone. The crystal is made of Hardlex, a heat-treated composite material containing barium and silicon that withstands scratching and marring better than glass. The hands illuminate with LumiBrite, a new luminous material brighter and longer lasting than conventional luminous paints, and completely free of radioactive materials, making it safer for both people and the environment.
