This has been the Swiss way at that time and this is something Gruen wanted to change with the precision factory.

But did they eventually? My naïve blue pill perception previously was that there were two categories of movements - those supplied by other Guild factories and marked with a factory letter, and the Precision grades produced at the Precision Factory. Evidently it was never that simple. Some of what I had previously assumed were entirely in-house movements actually started as outsourced ebauches.*

I also had the impression that around 1935 Gruen basically consolidated all production to be in-house at the Precision factory. Obviously by the 1950s they were clearly outsourcing movements, but was there ever actually a period during which all (or nearly all) Gruen movements were produced start to finish at the Precision factory?

*Which begs the question, what exactly differentiates Guild, Precision, and Extra Precision grades? I had assumed Guild meant outsourced, Precision meant in-house, and Extra Precision meant the highest quality in-house. It would appear that the scale did not have much, if anything, to do with source, but rather simply quality.
