Picked this guy up recently, I didn't take an "before" shots but it was pretty dirty. Washed it up in some warm soapy water and toothbrush and viola!, a beautiful example of the 5600C. Original band and bezel with intact keeper. This watch was in such good condition it still had the plastic protective film on the back case which you can see is pristine besides the slight buffing of the case back not covered by the the film. Crystal is darn near perfect. I think I can see a hairline scratch a few mm long but that I have to search for under direct sunlight to see. One of the best fully vintage examples I have seen short of collectors editions kept NIB.
