Funny that, i was going to make a thread asking who in Perth collect's vintage watches like yours....
I had my watch valuated today with Martin Karl Jewelery valuations (9321 9799, located in Perth City). He also gives a full detailed report on the item, item code, serial no., bracelet and model no.s along with the value and authenticity stamp.
To get even more $$$$ out of it, might help you also bring valid papers for the watch, it's original box and etc that it came with.
My 30 year old oyster perpetual is worth $7200
