I believe this watch to be from there period prior to 1924 due to the use of Philadelphia watch case co.
I believe rolled gold.
Watch is beautiful and in fantastic shape for a 100 year old watch. However the balance wheel is loose.
I have been told it needs a part to fix balance, so it will need repair.
It will tick sometimes when given a small roll.
Still a rare watch which I believe someone can fix
