What did I buy here?
A Semithin pocket with calber 754 watch in an Ultra quality case which thanks to it's inscripction can be dated to 1928. So far not unusual.
But if you take a look into the masterbook you will see that this case is listed as Empire44 as Verithin watch. There are two similar Semithins, but they have different bezels. Also the 1927 and the 1929 Guild books do not show this case being available as Semithin. So which Semi-Model do I have here?
