I have a 317 on order, I placed my deposit ( which was 20%) in May 2008 I rang up Panerai a couple of times and they told me that the watch hasn't been released this year and they say late summer 2009.
The boutiques will get theirs first and then the AD's around the world.
Im really tired of asking Panerai, AD's and everyone else. I liked the watch I put a deposit down and its down to Panerai when they deliver.....but isnt that one of the charms of Panerai when you get it you feel special.
50% is really too much for a watch they have no delivery date for, try and negotiate with them 20 - 25 % seems like the norm.
Hope you get one it looks a super special watch
