Other info: Re-posting Liz's Factory S "200" variant (with 16J) from previous forum threads. This began its life as an FHF ebauche, but it has a modified setting bridge and custom setting bits--so the usual FHF setting patent is not stamped on it. Noting it, as it explains why the setting bits shown in later movement catalogs (1939, etc.) are different: they reflect a modified/custom version of the "new" FHF setting works patented in late 1926. I doubt this caliber was actually in use past 1926, but Gruen was apparently still buying movements & parts to provide factory repairs.]]>Case2021-01-20T15:23:50-00:00Re: Caliber 200 & 201

Based off your post and the markings on this photo of 200 in 1926 parts supplement B here.
I'm thinking this must be a late production 200 below, correct?
Would you please be able to give me a more precise production date for this movement here?
I only have a window of 1922 to 1926....not sure how accurate that is.
Here is the dial side. I'm not including case data bc I it's likely a recase.
I guess my final thought or question is, what is the set in stone order of the full transitions of D version, S version, & G W Co version of 200?
Thank you!
