I think at some point they introduced watches with multiple lap memory and it may have been to distinguish between the two features? I'm not sure when it happened or if that was really the cause.
I also meant to add that the 38CR-12 had two variants, a blue and white stripe variant, though they were both a "-12". The one I'm holding is the blue variant and the white stripe variant looks gray because the back background and fine white lines. Also, of course there were other watches with running digital seconds, what I mean is the 25CR is the first Casiotron with running digital seconds. It also is the first Casio with the familiar modern pusher layout, I simply meant it is an early one and the operations will be familiar to someone accustomed to modern Casios.
Im not sure the C means casiotron. The C models were stainless steel, the Q models were a plated base model. You also had a G in there for gold plated. So these modules often had many variants. CR CS QR QS CGS CGR QGS QGR That 2 digit prefix as you know is just the module number, it would be in a box on a modern Casio's caseback.
Yeah, Casio wouldn't start listing the module separately on the case back for a little while, the F100's qw52 I believe was the first. This was also their first break from the 3rd era Casiotron naming convention and the first watch with the first of the two modern naming conventions. Module numbers wouldn't be displayed in the typical boxed format until later. I think the lowest boxed model number I've seen was in the high 90's, though I can't recall it now. But the Q models are definitely not all base metal, many are all stainless steel. The 31QR that was also included in my 31CR-10 video is a good example of this. As far as I can tell it's the first non-Casiotron branded watch and instead it has prominent Quartz branding on the dial. So to me C - Casiotron and Q - Quartz makes the most sense. In this video I also go over some interesting differences between the two 31CR and 31QR modules. th-cam.com/video/43BR6uLIFv4/w-d-xo.html
These all look nice.
Great history lesson. I wonder what year the LAP/SPLIT transition took place. Module 593 in the F-91 is LAP.

Casiotrons need more attention.
They should make some new ones with the 80's font seen here. Most watches were terrible time keepers then.
They reissued a 4000 limited edition casiotron
