OTHER TIPS
1) *Measure your finger in warm temperatures at the end of the day.
2) *If your knuckle is a lot larger than the base of your finger, measure both the base of your finger and your knuckle and select a size between the two.
3) *When considering a wide band, move up a size from your measurement, for comfort’s sake.
