For sale is a true collectors set Day-Date single quick 18038. 

The watch was just purchased from the estate of the original owner. The watch was purchased originally in 1989 in Saudi Arabia. 
The punched papers are stamped 1989 to corroborate this. The serial number is 5.9 million dating the case to late 1979/80. 

The original owner had the watch serviced 1 time in early 2000. Unfortunately he passed away later that year and the watch has been in a safe since then. 

Included with the sale is the complete set including, punched papers, matching hang tags, box set as well as the receipt from the service in 4/2000. 
The watch is very clean for it's age. The bracelet has 23 links, 6 screws and fits snugly on my 7.5 inch wrist. Bracelet is 85% condition. 

The crystal is free from any marks or scratches. 
The watch is running, keeps time and winds smooth. It has not been worn or serviced since 2000 so one may be in order.
