Hello Community need your help to see if I can have some more information about this watch because I m a Newbie on this subject.
Short Story: I inherited a watch (the one on the Pics) and I would love to have a little more information about it. I inherited this watch from my mother she was (as me) from the Gander family and she told me that this watch was hand made by an ancestor for him . So I have done my research and by the engraved monogram (that I believe it s a M) and the picture inside that I thing was it´s wife, I believe it was made by Marc Gander (the M) the Son of Emile Gander. But there an engraved name (R.WALDVOGII
? 12136) that confuses me and I don t know the meaning (see pic 3)... can someone help? And if you can give me also some info about the mechanism or other information I would be grateful. The side bottom that you can see activate a Bell that I don t understand why also 
Many Thkx for all your help
Paulo
