Questions about this item

Will the TPU strap on the C21 need replacing after daily wear?

The TPU sport strap is designed for regular outdoor use; replace it when signs of cracking or wear appear.

What limits the C21 during a full day of continuous heart-rate and GPS tracking?

Battery life is rated at less than seven days, so sustained sensor use will require recharging within that window.

Does the plastic case of the C21 get hot or noisy during all-day operation?

The watch runs silently with no fan; the plastic case stays at skin temperature during normal all-day wear.
