good solution to quickly switch.

Very good solution the clock quickly switch between bicycle and arm.
The holder does not bear too heavily on the handlebars when the clock is not attached, what me from an aesthetic point of my bike was important (old Italo Renner).
Only the annoying too short Velcro. Do not be particularly strong wrists, but it sits quite scarce. Two centimeters more and it would be perfect. Therefore a star deduction.
