You've gathered a very fine piece of Patek recent history with this 3700 set, congratulations 
Did you have it serviced?
I handled one in a shop one day but I will be interested to know, in the future, if you think it is a watch we can use as an everyday wear or if it is too fragile for this purpose.
As I said earlier to a fellow purist, I really keep asking myself if I should go for a 5711/1A too. The problem is that there are other references I wish to get as well.
As for the second box, I don't think it is the 40th Nautilus but a second 3700 or a specific version? I know you can do unexpected way!
Thanks a lot for sharing this, I'm glad for you.
Cheers, Mark
