Based on my limited knowledge of Patek timepieces, all three 3796 you have shown are rare items. The first one is a 3796D with a Hobnail patterned case. Very sall number of this watch were made, according to an old sales person. The second one belongs to a limited edition made for a Taiwan AD ( Wu Shan?) for its anniversary. The last one is of course a platinum one so no need for me to say too much. So congratulations again.
By the way, my wrist is also small and it has suffered a lot for bearing heavy watches, and needs a break sometimes with a light one such as 3796.
