The 6536/1 is a very underated watch, I feel! Usually the gilt printing is a wonderful dark copper, and there are many interesting details like white lollipop seconds hand and red triangle inlay.
Even though I really like my 5508, if offers less to look at! Only the 1530 movement is by far easier to service if you need spare parts!
The Sub you show is especially nice!

This was my 6536 CI!
This was my other 6536/1:

A friend here in Germany has two 6536/1 with white large seconds hand. In my database there are several more.
