Vulcain Cricket Nautical vintage

I am selling my second Cricket Nautical Vintage watch, a very rare beast!! I came across only 4-5 in my years of collecting and here is one with the nicest dial I have seen. The movement is running very well, currently around 40 hours when fully wound. According to the watchmaker there is no need for a service in the near future. The only down turn is the missing original outer caseback with the 16 holes- was replaced with a JLC caseback I suppose but works perfect. I sold my last Cricket for more than 7K and the caseback is teh issue which makes the watch cheaper. I am interested in Rolex trade-ins - Plexi if possible- and money up or down is no problem. Also, rare parts from Rolex and other watches are interesting for me. Watch and I are in Munich, local pick up is welcome. TOns of references in the vintage Rolex world, just ask! Here you go with the scans:

Thank you! Michael
