I have created a heavily illustrated serial number database for C.H. Meylan pocket, purse, and pendent watches, with the goal of fostering a better understanding of this important maker's production. Here is a link to it: https://www.dropbox.com/s/nimopjwit3iivli/C.H.%20Meylan%20Serial%20Number%20Database.doc?dl=0 The database begins with my tentative conclusions, as to which I would be grateful for your input and comments. If you have any C.H. Meylans, please send me photos and a description if I haven't already listed the watch in the database. I will add your watch when I next revise the database.
