My 90 year old father gave this to me. It is an IWC he picked up in Hong Kong about 60 years ago. It has been relatively untouched. The watchmaker who inspected it could not identify it, but you can clearly see the serial number on the case, but not the model number or the caliber.

Any help in identifying this piece would be greatly appreciated.
