Okay, let's get one thing clear, I DID NOT buy a dozen watches!! That would be crazy, even for me! :-D Here is the very large EMS bag that arrived. Inside the bag, a very tidy bundle. And that bundle breaks down into six smaller, tidy packages! Let's pick one at random. Since this is my second package deal with this seller, I'll call this item "2a". Under the wrapping a free plastic storage box. Inside the storage box, what looks like a watch! Yup, it's a watch, it looks like a old Seiko. In fact it is a 1969 Seikomatic-P Weekdater, model 5106-7030, with a 33 jewel automatic, hacking movement running at 19800 bph. It is in good shape overall with an interesting tree-bark-like texture to the dial, but with some white deposit on the underside of the crystal. I may put on my big-boy pants and open this one up and try to clean the crystal myself. It will be fun to have a project! :-) The crown side, with the distinctive hexagonal center-pusher that is used to quick-set the date. The other side... And finally, the vitally important, vintage watch case-back view. Okay, only five more to go1 :-D Please look for further postings, "Seiko Package Deal 2b", "Seiko Package Deal 2c" and so forth, okay? Thanks for clicking in! - Thomas |

Well, it is nice looking, but I do have to tell you there is 1 problem ... It is NOT a -7030. I have 2 of these and the model (case-style#) should be: -70 50 They had 2 (AFAIK) dial types, the "wave" style as shown & another with a "linen" dial which I believe has a 7060 dial code. Here is the 1st one I got in early 2000s:   But, I got a nicer one in recent years here on Philippine eBay. I'm looking for more pics in servers, but I'll post this for now & update if I find them later. ... AT ANY RATE: it seems you have a swapped case-back there on yours!! |

Well, here's the back shot of that 1st example.  I've not yet found easy/quick access to links of the pics of my 2nd example that are hosted online. UPDATE: OK, found them!!  The pics have unflattering lighting & color balance, but it is actually in better shape than my 1st example!! Fortunately, the bad pics kept the price quite low  ... and the results, upon arrival, were wonderful ... much nicer than I'd expected!!  Again, you can see the case-style is -7050. This should also be verifiable by checking out the archives at "Seikomatic" (Japanese reference site). Quite a lot of original case texture on this one as you can see below:   Clean movement too!  I can't remember off the top of my head if it is an original style bracelet, but it is vintage Seiko anyway! |

As always Ninja, thank you for your attention to the details! All of this helps me learn about this vintage Seiko business.  So it doesn't matter that the dial code is 5106-7031?  I had though that indicated a 5106-7030 series watch, with 7031 dial variation. I guess not? :-/ - Thomas |

OK, I did just check w/ the 5106 Archive @ Seikomatic: www.h4.dion.ne.jp/~smatic/51series/5106/51mwarc.htmlThey do show a -7030 model that seems (almost?) identical w/ the -7050 & interestingly, they don't have a -7050 shown there. Well, I've seen that type of thing before, sometimes Seiko made 2 different case types that were almost identical & minor differences in dial. Now, since you did say the dial code in an earlier response, it does make logical sense to conclude yours is a -7030. And, I do see what went on in my mind when commenting on your watch. I lost track of the fact that yours is a Seikomatic-P, while mine is a " Presmatic"!! So, yours is the JDM version while mine is the export version of (essentially or exactly) the same case design. So, I suspect I caused a bit of a panic while in a rush to answer. However, to answer your earlier question: the dial code and case style code do NOT always match in the next to the last digit & last digit. I can tell you that in the chronographs like 6138, very often the 2nd to last digit is different - for example, the "Big/Small Eye" type which has case style #s like 6138-00 11 will have dial codes that are like 6138 00 20 (or similar). However, in dress watches of smaller variety/numbers of distinct case styles, I have seen more correlation between case & dial codes. I am puzzled that Seikomatic makes no reference to a -7050 as a "Presmatic" in their archive page BUT I do know that they rely on what info they can come up with and are not perfect or guaranteed to be complete in their listings of "models". So ... I think you are safe with this one after all!!  ...  |

Hi Ninja, No problem on the false alarm, this kind of healthy investigation is how we find out stuff!  It's like science! And I was just coming over here to add that a gentleman on "TOF" made the same observation that you have: "The caseback on your 5106-7030 is correct, the -7050 case is for the export Presmatic model (thus the Presmatic engravement on the caseback), while your watch is the JDM Seikomatic-P model.
AFAIK, the two cases (7030 and 7050) are technically the same, but for different markets."
So, case closed. Keep up the good work dude! You folks are helping me learn every day, and I am amazed at how much information is available in various online databases!
