I've just stripped down a 6106 that was from a DX watch with a one-piece case- the one with no caseback and you take the movement out of the front after removing the crystal.
It is missing the date corrector and the date corrector finger, though it does have the date-corrector spring. At first I assumed that someone had just put it together without those two parts because they had lost them, and didn't mind the fact that it means you can't quick-set the date.
Then I noticed that because this movement has the small tab that sticks out from the side to enable you to remove the stem (which the 6106 from the standard case designs don't have), then the mechanism of the date corrector finger wouldn't work. So it was like this when it left the factory?
In other words, due to the one-piece case design, they had to slightly modify the movement by including the tab and excluding 2 parts, which reduced the functionality of the watch...
But then why on earth include the date corrector spring, which is now completely redundant?
"Normal" 6106a:
The circled parts are the ones missing from the "modified" 6106:

Seiko have been known to do this sort of thing in other movements before as well - the 6245 has all the parts for the day mechanism as the 6246 does, just without the actual day wheel. It has the day and date driving wheel, day jumper and spring, which are all not necessary for it.

Interesting. But at least in that case they changed the movement number. My two movements are both 6106A.

Those missing parts, should not be missing in an original movement. It's designed to accommodate all types of stem release lever, whilst maintaining full functionality - or the tech pdfs would mention this. Please have a look at this site, to compare yours thewatchspotblog.com/?p=124 |

That makes more sense. So my "modified" movement is in fact a 6106B but had the plates swapped out with a 6106A, and missing a couple of parts.
Thanks!

6106A does not have a quick set day + date. They weren't introduced until the "B" model.
