I saw only one 5396 in one of the AD's here in Bangkok also. It's a nice wach but it's a little small on my 8 inch wrist and I'm not particulary fond of the snap back case. Also I think Patek opened the new factory with the intent to increase production of watches due to the opening up of the Chinese market. I would GUESS about 100k watches a year with a lot of them, maybe 50%, being quartz. Women make up a large part of their clientel now. As far as anyone guessing about the numbers in a regular production reference that's a toss up. The only people who know the exact number aren't speaking. I believe you are correct with the statement about batch production of references.
