IWC cal 83 18k yellow gold

I have here a lovely IWC cal83, 18k yellow gold watch, dated to the 1940s.

Original dial, with small amount of blemishes and age spotting , which is more obvious under macro and flash photography than to naked eyes. For a 70+ year old watch, it's in an outstanding condition. The case is still in very good shape. Hands have small amount of oxidisation but these are genuine hands. It's signed on the dial and the case cover. Crown not signed (which is normal for watch of this period).

The movement, IWC cal 83, serviced 2 years ago. Watch and myself are located in Sydney, Australia. Watch references available, although a bit out of date as I haven't sold a watch in awhile.
Case diameter 35mm without the crown.
asking USD$3700, or AUD$3966, paypal and shipping included. For international , I ship with EMS with tracking. Insurance (if required) +/- custom duties is payable by buyer.
