Αυτά μπόρεσα να βρω.
Τώρα για την μετάφραση,εάν κάποιος δυσκολεύεται, ας κάνει τον κόπο να χρησιμοποιήσει ένα πρόγραμμα μετάφρασης.
Αυτό που κρατάω, είναι ότι :
α)οι 7s26 και 7s36 είναι η συνέχεια της σειράς 7005.
β) η διάμετρος είναι η ίδια (27 χιλιοστά)
γ)οι παλμοί την ίδια συχνότητα (21600 την ώρα)
"Since we are servicing a 7005, a good opportunity exists to compare this movement to the 7s26, which along with the 7s36, is the latest incarnation of the 7005 series. The 7s26 and 36 are found in the current range of Seiko 5 mechanical watches. Comparing it to the 7005 above, its lineage is more than a bit obvious. There are some differences in design of the keyless works and the calendar mechanism. In my opinion, the calendar mechanism of the 7005/9 watches is superior in design and construction. Also, despite the extra jewels (4) of the 7s26, the overall quality of finish is substantially lower than its predecessors. Seiko has made no attempt whatsoever at any decorative finishing of the plates, only finishing or polishing mechanical working surfaces where functionality requires."
"Again, we will pause briefly to compare the 7005 movement to a 7s26. This pic of the 7s26 shows the day ring removed. Both the day and date rings are plastic (in the 7005 they were metal), as are the 2 white corrector wheels for the day and date, and the 2 wheels driving the date ring. Also, the detents and springs for the day and date wheels are made as an integral part of the date jumper plate and dial guard, rather than as separate components (in this pic, only the day detent is visible). Being stamped from brass shim instead of the traditional steel, they are quite flimsy and prone to distortion if not handled carefully during service."

"If you have persisted in reading this far, you may have reached a conclusion that I don't like the current series of 7s26 and 7s36 movements, and that they are inferior to the 7005. Well, this is not really my intention. While it is true that the quality of decorative finish on the 7s26 is not as good as previous models, it is worth noting that the same comments can be made about workhorse Swiss movements such as the Eta 2824/36, the Eta 2892, and the Valjoux 7750. These movements bear little resemblance in finish quality to their predecessors from the 1960's. I guess the bottom line is that economic necessity has forced watch manufacturers everywhere to streamline production techniques, which unfortunately can mean omitting non-essential manufacturing operations, such as the decoration of unseen parts.
From what I have seen, the 7s26 movement is a very reliable workhorse, and capable of very good performance. Their ruggedness and reliability is well-known, their basic design has been tried and proven over decades in various forms. While we now have to pay a lot more for highly finished mechanical movements, perhaps we are lucky to still have available to us very affordable mechanical watches that we can collect and enjoy. "
