Q: Does this watch have a tachymeter?

Not directly. However, you can divide 3600 by the number of seconds it took you to travel one mile to calculate your speed in miles per hour. Line up the '10' on the outer dial with the number of seconds it took you to travel one mile. Look at the 36 (3600) on the inner dial. The number on the outer dial over 36 will show your speed in mph . If it took you 36 seconds or less to travel one mile, multiply the number on the outer dial by 10.
