Dear all Pro users.
if you are frustrated with just the limitations of your original watch strap, you can head to any Fossil store and buy the "22mm" watch straps. It fits perfectly.
I have researched and tried (modifying) many brands of strap from Fitbit Ionic to Fitbit Versa to Conventional bands in the market. Any 22mm will work but make sure you get those with the quick release hinge.
Hope this information helps.
