Adjustment should be completed gradually because removed sections cannot be reattached. Determine your approximate wrist fit before cutting Trim only one adjustment section at a time Test the strap after each adjustment Adjust both sides carefully to keep the butterfly clasp comfortably centered Important: Once the strap has been cut, trimmed, or permanently modified, the removed sections cannot be restored and the product may no longer qualify for a change-of-mind return.
