Hi all. As I have sold my soul to The Cult of the Double Security, I am now ready to part with noncritical organs, firstborn child etc. for some hard-to-find parts... Certina 5601 013 Bezel: From here. Certina DS PH200M Bezel and dial: From here. The PH200M bezel is also used on some Favre-Leuba divers, so isn't that uncommon to find - I realise that I have to be extremely lucky to source the two other items
A year on and I am not much closer... To give some perspective on pricing, I recently came 2nd in an auction for a PH200M bezel, which ended at around €500. It was NOS, which was why I couldn't bid more; I would much rather have on in good condition at €250-300 than one in NOS condition that would look too new on the watch for €500. For an example of a Favre-Leuba with the same bezel, have a look at @Dan S' post here on What Did You Buy...
