Gift for Great Grandma?

My 97 year old great grandmother is moving into assisted living for the first time this month because she is no longer able to care for herself. I want to get her a nice Christmas present to cheer her up, but I'm at a loss as to what to get her. Given that she won't have much space in her new home, I don't want to get her something she won't need or won't use regularly. Unfortunately, I don't know too much about her interests, other than she enjoys reading harlequin novels and likes clocks and watches. Unfortunately, she already has too many of the latter, and I would be uncomfortable giving her the former. Any suggestions would be appreciated.
