I was searching the old RWG (ssh, don't tell anyone)... and found this picture of Richard Lawton's solid 18K gold Day-Date. It was purchased from Paul in 2004, and I recall the price was something around $2.5K. Yes, it IS real solild gold.
Personally, I'm not a fan of DayDate/DJ line, but this is quite amazing rep if you ask me. I hope you don't mind Richard, but this watch deserves a thread here as well.
Picture by Richard Lawton of course.
