I thought this Opera watch was interesting with the power reserve. It has a nicely finished movement F760 and the case is gold capped over SS. The marker at 9:00 has come off and is at 1:00. Can't find much about this company other than another member who posted pics of his on WUS. Looks like 1955 is about the year made.
Also, got this Rytime Rotomatic with an AS1361N movement. The case and lugs have a cool shape and are kind of scalloped. It also has these metal loops on the case surrounding the movement that I assume is to make the case more water resistant. It has Fairfax Watch Co on the rotor. Would be interested to know the date of these two. After a little research it looks like, ironically, they are both 1955.
