Acquired this fine timepiece in the shadow of Santa, love him. As you might have recognized I am now going vertical in my collecting and learning journey into Glycine and Meylan pieces.
I have enough information about the base caliber and the automatic module, but about the case I need your help for the marks to identify. Also this aparat has an interesting clips alike crown function which holds the two pieces case together and sets the time also, never saw this before.
The dial is signed ' Dietrich Bale' , I know that Bale is the city Basel in French influence, but couldn't find who was 'Dietrich'. At one source it was mentioned retailer, but don't know if Jeweler or something else, saw an IWC with the same dial sign . Any info on ' Dietrich ' and case marks would be appreciated,
