Gruen Chronograph Valjoux 7730 Watch
Offered is this FULLY SERVICED Gruen Valjoux 7730 Chronograph with tachymeter and telemeter scales. The watch winds, sets, and runs great. It keeps excellent time, and the chronograph feature works flawlessly. The Tachymeter scale in blue measures speed in miles per hour by measuring the time it takes to cover the distance of a mile (such as starting the chronograph when one passes a mile marker and stopping the chronograph at the next mile marker-if it takes approximately 55 seconds to travel the mile, you are traveling at approximately 65 miles per hour). The dial also features a Telemeter scale in red, which measures distance in miles from an event using time required for sound to travel from the event.
