Returning an unused Garmin watch

EmmaLP

Hi, has anyone had experience of returning an unused but opened and turned on Garmin watch. I recently purchased one for a gift for my husband. He turned it on but realised the type size was too small. I've returned it to John Lewis but they won't take it back. They have said as its not in original condition they wont take it.
On their returns page it doesn't state anything about not turning it on. I believe their T&Cs are out dated and don't cover Garmin type watches as it just says jewellery and watches returned in store but doesn't say they shouldn't be turned on. Is this correct and legal?
