Lot silver and rose gold Luxury pocket watches & spare-parts

I am not able to find any remarks to the maker other then the little signes shown on the casing etc.

The total lot contains  2 pocket watches with engraved silver and rosegold casing whih I assume are complete. Other then that I have 2 solid silver casings unmarked, and then some enamel dials and mechanical parts. Please advise me  us! 

Thanks in advance.
