Vincent Calabrese “Mona Lisa” Jump HourModel: Vincent Calabrese Mona Lisa Jump Hour Year: Mid '90s Features: The Origin. Vincent Calabrese is a name that might be immediately familiar to watch enthusiasts. I had the pleasure of showcasing his work not once, but twice last year. Each time, he offered us his unusual take on a jump hour watch, and today is no different although this might be his strangest example yet. The Complication. On the surface, this Mona Lisa is a conventional watch.
