Strap Length Guide - HydroFlex

Our HydroFlex™ straps are available in one length.

Strap	Wrist size (inches)	Wrist size (cm)
HydroFlex™	6.1" to 7.3"	15.5cm to 18.5cm

Note: The HydroFlex™ strap can fit wrists larger than 7.3” as well (up to 7.75”/19.6cm) but then you may be wearing it on the second-to-last or last hole.

How to measure your wrist size

You can either use a tape measure to do this, or use a simple strip or string as shown below.

Step 1 – Wrap the strip/string around your wrist at the point where you wear your watch.

Step 2 – Measure the strip/string using a ruler.
