https://www.sothebysaustralia.com.au/list/AU0841/181# Sotherbys Australia has a BA145.022 up for auction on the 4th of December.They have followed the guarantee paperwork and listed it as a 345.022.If the serial matches with the watch all is fine. Estimate is $30,000 to $50,000 Australian Dollars. Not to many photos to make a good judgment of the condition. I don't think the box is an original crater box but I have never seen one to make comment. 22% buyers premium plus 10% GST. Whats your best estimate?
