Garmin watch straps are made of rubber, making them very comfortable to wear, easy to clean, and they do not interfere with the optical sensor for monitoring your heart rate. This is why the bands are interchangeable on most Garmin watches. The strap is attached by two small pins and can be removed by pressing down on them with a paper clip or other similar object. The pins will pop out, and then you can slide the band off your device. There are some exceptions to this rule, though. Some devices have a metal buckle that attaches directly to the device and cannot be removed without breaking it off with pliers or other tools. Most Garmin watches are intended for daily wear, not only because they look great on your wrist but because the heart rate monitoring straps monitors your heart rate over an extended period. The general rule of thumb is to wear the band so that there is a finger's width between the band and your wrist. This way, there's room for blood circulation, providing more accurate data. When the band is too tight, and you are trying to sleep or rest, this may hinder your ability to get an accurate reading.
