About a week ago I submitted a picture of this 16 size Swiss movement with an unusual marking, but have had no luck yet in helping identify it. I've decided to re-post the pic, as well as another view of the other side of the movement, to see if it helps anyone recognize it. It is an English Sterling case dated to 1919 and appears to be a quality piece. Any ideas?
The second watch, also Swiss, is signed 'Lusitania' and has a rather unusual acid etched design on the movement. I was told that 'Wilsdorf & Davis' may have trademarked the Lusitania name and issued these watches as commemorative pieces celebrating the launch of the doomed liner, but have not been able to confirm this story, nor the actual identification of the movement. There are some similarities to early Omega movements, but some differences also, so any help appreciated.
