The design is clearly inspired on Mondaine's one: the seconds handle is exactly the same. I see it more of a homage than plagiarism, though. It would be plagiarism if it were a physical clock with the same design and they were selling it. It's not like Apple makes money selling this app. Mondaine has the right to ask for change or compensation if they feel they got ripped off, though.
