Irony here is that seiko hasn't got any thin movements anyway so a thin moonphase complication isn't going to help their 15mm thick dress watches....
Quite a good read about a rather interesting moon phase mechanism recently patented by Seiko Corp.
"This design allows for a much larger and easier to read moon phase representation to be positioned in the same area as a traditional moon phase display. It is also able to be implemented in a relatively thin movement design".

Ingenious implementation but doesn't solve issue I see with most MP complications - moon being rotated compared to what is actually observed in the sky.

It will probably be a 4 inch thick moon phase with a steel stamped clasp.
