Mark Lovick, creator of Watch Repair Talk, has just put up a three-part (+ bonus) video tutorial showing him servicing a 7S26-0020:

  1. Disassembly
  2. Assembly: Gear train
  3. Assembly: Motion work & calendar
  4. Extra: Removing mainspring from barrel
They're in his usual clear style and easy to follow, although watch out for the mistake with the calendar pinion at 3:42 in the third video (he corrects it in the description and annotations).

I would've liked to know more about the the oils he's using at each stage to compare with the Seiko technical manual, but hey, it's still a great resource.
