Patek Philippe

ref. 1578; cal. 27SC...  

Any pics of the movement? Also...love the leaf hands...are those original to that ref.?

Yes, the leaf hands are original to this particular watch. as is the blued second hand. However, this ref. (1578) came in a number of variations, and I have seen an example with Dauphine hands, as well as early variations with a sub-dial rather than cente... 

approximately what time period was this watch made in and what is it's diameter? Congratulations on a great acqusition...wear it well...
