Lloyd, I am astonished, you do not know the answer to this.
The Auto-Set, line-segment P3s, were done with frankenmodules, constructed with a P3 plastic carrier, with a P4 circuit board grafted onto it (I have also seen a variation that used a Dress board, since the displays are similar in height; obviously, the Dress version does not have provision for the Auto-Command function). There is no such thing as a 3035 module; I assume you meant 3050.
In the Calculators, the difference between the 902 and 903 modules is that, using the Auto-Command, if you flick your wrist a SECOND time, WHILE THE TIME IS DISPLAYED, it switches to a DATE display. I estimate that about one in 12-15 902s are actually 903s, but have gone unnoticed. Everyone should try their 902s, and let's see how many 903s pop up...(I may have to revise my estimate...lol).
So...back to the 3050 mystery...
On a standard 301(3) module, the DATE display stays on as long as the button is pushed (a fraction of a second, or an hour...makes no difference). On a 305, even if the button remains pressed, the display extinguishes after 1.25 seconds (in other words, the Date is displayed the same way the Time is). What is most important here, is that this is exactly how the Time and Date are displayed on a P4 model...which means, we have a P4 chip on a factory-made P3 circuit board. Some modules actually have a sticker tag that says "Module 3050" attached; most do not.
To me, all this suggests an experimental, transitional step between the P3 and P4 models. I am open to other interpretations, but this makes the most sense to me.
Again, everybody with a P3 should check for this variation...it might turn out to be much more common, or maybe rarer, than I thought.
Does it add to the value of the watch? A fair bit, I would think, but fundamentally, a P3 is still just a P3. Let's see how the numbers shake out...
