Featuring two displays for measuring time; an analog clock and the ability to use the chronograph for under and above 1 hour. Lume can be found on the baton indexes as well as the two main hands. Operating from a 38 – jewel caliber 39 automatic movement. This watch is in excellent condition with light scratches and one notable scratch on the case back.
