It turns out that my friend doesn't have paperwork and will need to remove bracelet to find out for sure. The timeframe fits in with it being about right. The first detail I remember is that it cannot have an inverted 6 to be a Patrizzi. It was named after the collector who liquidated part of his huge collection including some oddly brown sub-dialled Daytonas.
