Thank you both — I mean also Dan — for the info. Funny because I had thought of using “sweet pocket watch” as a title for the discussion, but then I figured that "sweet" didn't sound very professional.
Anyway, I had thought about having VC expertise the watch, but I also figured that It probably isn't cheap -– as far as I know, cheap and Switzerland don't ever appear in the same sentence — but I thought it might be better to first know if the watch had some chance of being a true VC: I am sure I can trust the opinion of someone with a nick so cute as tick-talk. Anyway, as I would be really unconfortable with sending the watch by courier and I don't plan to go to Geneva soon, getting VC's expertise will take quite a while.
As you may well imagine, I do not intend to open the watch, the mere idea of doing it make my hands shake, so I may not answer your question about numbers. Also I don't know much about different types of enamel. The date, 1830 ca, fits perfectly with family history. I have one question: rather than a pocket watch, would this not be a ladies pendant watch?
I haven't yet found anyone more confident with a camera, but thanks to daylight I have obtained better results with my ipad: hope you enjoy the new picture and notice how absolutely sweet the rear of the case is. If you care for other ipad daylight photos, please ask. Of course I well understand that I can't expect absolute answers over the net and with such low quality photos.
Best regards to both
