Yes, on some watches (not stop watches to my limited knowledge) that outer scale is a tachymeter which allows the determination of a groundspeed by timing how long it takes to cover a mile.
The 360 on that stop watch is a bit beyond me unless it's a tachymeter using some other set of distance measurements. Someone will undoubtedly have an answer here. I can't noodle out how it could be related to 360 degrees of a compass rose.
