Ladies Vacheron model 27609

Hello,  this is my first time posting in Hour.  I'm wondering if anyone has information on a Ladies Vacheron watch (model no. 27609, individual no. 661640), it is currently in Switzerland for restoration and authentication.  I am unable to find any information on this watch, only that it is authentic.  The watch is a 18ct yellow gold band with a pink heart shaped diamond face.  I have searched the internet and can find nothing similar and cannot place a date on it.  If anyone can provide information or feedback, it would be most appreciated. 
I'll see if I can find something but if you have alreadw requested a

Hi, thanks for the reply.  How would I find the value of the watch...my employer has requested I value the watch, but since I cannot find a similar model I do not know where to begin?
