Hi everybody, I’m sorry if I didn’t read this question before and my answer is late.
The reason is very simple: as we explained in the introduction of our book, we needed to define a strict perimeter for the models, otherwise it would have been too large and too difficult. So we decided to exclude 1) quartz and self-winding movements and 2) different case shapes.
So the question was not to say if the DSOTM (beautiful watch!) was a Moonwatch or not, but more to define logical criterias to manage the perimeter of the book.
