Before you dismiss the possibility out of hand, consider:
1) The dial lost the power reserve
2) There is a big date, day and moonphase. As a mechanical, all three would need to be corrected upon watch reset.
3) The small seconds has only twelve tick marks, not the 5 7 1 2's sixty tick marks. (Significance explained below.)
As a quartz watch, this is the dial of a big date perpetual calendar moonphase watch. The annotated photo explains how it all works.
Inside, there are 3 motors:
1) main motor for the minutes and hours
2) second motor for the small seconds
3) third motor for the big date
When setting the perpetual calendar in the outermost crown position, you first set the date. Then you push the crown in, pull out again quickly, and see the seconds hand jump to one of the 12 hash marks, You set the month. Another push/pull and the seconds points to one of 4 cardinal directions, Set the year of the leap year cycle. This is method patented by Rolex in 1987, and is now in the public domain.
Well, maybe I am wrong the above is another mechanical. But does it make sense to have day of the week, which is yet another thing to correct?
